However, though some researchers have proposed effective methods for mining user habits such as behavior pattern mining, how to leverage the mined results for discovering similar users remains less explored. To this end, we propose a novel approach for conquering the sparseness of behavior pattern space and thus make it possible to discover similar mobile users with respect to their habits by leveraging behavior pattern mining. To be specific, first, we normalize the raw context log of each user by transforming the location-based context data and user interaction records to more general representations. Second, we take advantage of a constraint-based Bayesian Matrix Factorization model for extracting the latent common habits among behavior patterns and then transforming behavior pattern vectors to the vectors of mined common habits which are in a much more dense space. The experiments conducted on real data sets show that our approach outperforms three baselines in terms of the effectiveness of discovering similar mobile users with respect to their habits." ; swrc:month "April" ; swrc:year "2012" ; foaf:maker , , , , . a swrc:InProceedings ; rdfs:label "Review Spam Detection via Time Series Pattern Discovery" ; swc:isPartOf , ; dce:creator , , , ; dce:subject "Time series" , "Review spam" , "Temporal pattern mining" ; dce:title "Review Spam Detection via Time Series Pattern Discovery" ; bibo:authorList ; swrc:abstract "Online reviews play a crucial role in today’s electronic com-merce. Due to the pervasive spam reviews, customers canbe misled to buy low-quality products, while decent storescan be defamed by malicious reviews. We observe that, inreality, a great portion (> 90% in the data we study) of thereviewers write only one review (singleton review). Thesereviews are so enormous in number that they can almostdetermine a store’s rating and impression. However, exist-ing methods ignore these reviewers. To address this prob-lem, we observe that the normal reviewers’ arrival patternis stable and uncorrelated to their rating pattern tempo-rally. In contrast, spam attacks are usually bursty and ei-ther positively or negatively correlated to the rating. Thus,we propose to detect such attacks via unusually correlatedtemporal patterns. We identify and construct multidimen-sional time series based on aggregate statistics, in order todepict and mine such correlation. Experimental results showthat the proposed method is effective in detecting singletonreview attacks. We discover that singleton review is a signif-icant source of spam reviews and largely affects the ratingsof online stores." ; swrc:year "2012" ; foaf:maker , , , . a swrc:InProceedings ; rdfs:label "Paraimpu: a Platform for a Social Web of Things" ; swc:isPartOf , ; dce:creator , , ; dce:subject "Social Networks" , "REST" , "Internet of Things" , "Web of Things" ; dce:title "Paraimpu: a Platform for a Social Web of Things" ; bibo:authorList ; swrc:abstract "The Web of Things is a scenario where potentially billions of connected smart objects communicate using the Web protocols, HTTP in primis.

Recently, a number of machine learning algorithms have been proposed for representing the data to be searched as (short) bit vectors and then using hashing to do rapid search. These algorithms have been limited in their applicability in that they are suited for one type of task -- e.g. Spectral Hashing learns bit vector representations for retrieval, but not say, classification. In this paper we present a unified approach to learning bit vector representations for many applications that use nearest neighbor search. The main contribution is a single learning algorithm that can be customized to learn bit vector representation suited for the task at hand. This broadens the usefulness of bit vector representations to tasks beyond just conventional retrieval. We propose a learning-to-rank formulation to learn the bit vector representation of the data. RankNet and LambdaRank algorithms are used for learning a function that computes a task-specific bit vector from an input data vector. Our algorithm outperforms state-of-the-art nearest neighbor methods on a number of real world text and image classification and retrieval datasets. It is scalable and learns a 32-bit representation on 1.46 million training cases in a day." ; swrc:month "April" ; swrc:year "2012" ; foaf:maker , , . a foaf:Person ; rdfs:label "Kapil Singh" ; swc:holdsRole ; swrc:affiliation ; foaf:based_near ; foaf:firstName "Kapil" ; foaf:lastName "Singh" ; foaf:made ; foaf:mbox_sha1sum "738f9b6d53c9e71511e194014ef3e5dcfe7047ea" ; foaf:name "Kapil Singh" . a foaf:Person ; rdfs:label "Sid Stamm" ; swc:holdsRole ; foaf:firstName "Sid" ; foaf:lastName "Stamm" ; foaf:mbox_sha1sum "404276e8c532fafb81c7a690813b8feeba5224ea" ; foaf:name "Sid Stamm" . rdf:_1 ; rdf:_2 ; rdf:_3 . rdf:_1 ; rdf:_2 ; rdf:_3 ; rdf:_4 ; rdf:_5 ; rdf:_6 ; rdf:_7 ; rdf:_8 . a event:Event , swc:TalkEvent ; rdfs:label "Paper presentation: Automated Linking Data with Apache Stanbol" ; swc:hasLocation ; swc:hasRelatedDocument ; swc:hasRole ; swc:isSubEventOf , ; event:agent ; event:place ; icaltzd:location ; icaltzd:summary "Paper presentation: Automated Linking Data with Apache Stanbol" . a swrc:InProceedings ; rdfs:label "Google Image Swirl, A Large-Scale Content-Based Image Visualization System" ; swc:isPartOf , ; dce:creator , , , , , ; dce:subject "Content-based image retrieval" , "image search" , "browsing models" ; dce:title "Google Image Swirl, A Large-Scale Content-Based Image Visualization System" ; bibo:authorList ; swrc:abstract "Web image retrieval systems, such as Google or Bing image search, present search results as a relevance-ordered list.

We use these improved estimates of query intent, along with the query intent based on the search language data, to compute features that encode the similarity between a search result (URL) and the query. These features are subsequently fed into the ranking model to improve the relevance ranking of the documents.

VCPs provide nearly complete information about the surrounding local structure of embedded vertex pairs. The VCP approach offers a new tool for domain experts to understand the underlying growth mechanisms in their networks and to analyze link formation mechanisms in the appropriate sociological, biological, physical, or other contexts. The same resolution that gives VCP its analytical power also enables it to perform well when used in supervised models to discriminate potential new links. We first develop the theory, mathematics, and algorithms underlying VCP. Then we demonstrate VCP methods performing link prediction competitively with unsupervised and supervised methods across several different network families. We conclude with timing results that introduce the comparative performance of several existing algorithms and the practicability of VCP computations on large networks." ; swrc:month "April" ; swrc:year "2012" ; foaf:maker , . a swrc:InProceedings ; rdfs:label "The Impact of Visual Appearance on User Response in Online Display Advertising" ; swc:isPartOf , ; dce:creator , , , , , ; dce:subject "Ads visual appearance" , "Online display ads" , "CTR prediction" , "online ads (creative) design" ; dce:title "The Impact of Visual Appearance on User Response in Online Display Advertising" ; bibo:authorList ; swrc:abstract "Display advertising has been a significant source of revenue for publishers and ad networks in the online advertising ecosystem. One of the main goals in display advertising is to maximize user response rate for advertising campaigns, such as click through rates (CTR) or conversion rates. Although the visual appearance of ads (creatives) matters for propensity of user response, there is no published work so far to address this topic via a systematic data-driven approach. In this paper we quantitatively study the relationship between the visual appearance and performance of creatives using large scale data in the world's largest display ads exchange system, RightMedia. We designed a set of 43 visual features, some of which are novel and some are inspired by related work. We extracted these features from real creatives served on RightMedia. Then, we present recommendations of visual features that have the most important impact on CTR to the professional designers in order to optimize their creative design. We believe that the findings presented in this paper will be very useful for the online advertising industry in designing high-performance creatives. We have also designed and conducted an experiment to evaluate the effectiveness of visual features by themselves for CTR prediction." ; swrc:year "2012" ; foaf:maker , , , , , . a foaf:Person ; rdfs:label "Michael Mahemoff" ; swc:holdsRole ; swrc:affiliation ; foaf:firstName "Michael" ; foaf:lastName "Mahemoff" ; foaf:mbox_sha1sum "74bd79e3cb167bee345245c8ada525179ccc5ede" ; foaf:name "Michael Mahemoff" . a foaf:Organization ; rdfs:label "Korea University" ; foaf:member , , , , , , ; foaf:name "Korea University" . a foaf:Person ; rdfs:label "Daniel Lacroix" ; swc:holdsRole ; swrc:affiliation ; foaf:firstName "Daniel" ; foaf:lastName "Lacroix" ; foaf:made ; foaf:mbox_sha1sum "fe9b502eea26d835bbc9f8c7c7bf8b057497f0eb" ; foaf:name "Daniel Lacroix" . a foaf:Person ; rdfs:label "Benno Stein" ; swc:holdsRole , ; swrc:affiliation , ; foaf:based_near , ; foaf:firstName "Benno" ; foaf:lastName "Stein" ; foaf:mbox_sha1sum "97dd6ba9cbeb9e5fc1f22d98d32bab1b8f6fbefc" , "f99e406dc9986a385127475c99a7ebd26f3a3819" ; foaf:name "Benno Stein" . rdf:_1 . a foaf:Person ; rdfs:label "Sedat Gokalp" ; swc:holdsRole ; swrc:affiliation ; foaf:based_near ; foaf:firstName "Sedat" ; foaf:lastName "Gokalp" ; foaf:made ; foaf:mbox_sha1sum "1635d667a799706b1929f545a8226896b1d2f46c" ; foaf:name "Sedat Gokalp" . swc:heldBy , ; swc:isRoleAt . a foaf:Person ; rdfs:label "Sihong Xie" ; swrc:affiliation ; foaf:based_near ; foaf:made ; foaf:mbox_sha1sum "cc7fabb68f3c0a740e58422bd0e72edfd9735451" ; foaf:name "Sihong Xie" . a foaf:Person ; rdfs:label "Jaime Teevan" ; swrc:affiliation ; foaf:based_near ; foaf:firstName "Jaime" ; foaf:lastName "Teevan" ; foaf:made ; foaf:mbox_sha1sum "b12653c0225f76c264d712c402660a35be3d4ec4" ; foaf:name "Jaime Teevan" . a foaf:Organization ; rdfs:label "Oregon State University" ; foaf:member , ; foaf:name "Oregon State University" . a swc:Chair ; rdfs:label "Metadata chair" ; swc:heldBy , ; swc:isRoleAt . a foaf:Person ; rdfs:label "Ashutosh Jagdish Sharma" ; swc:holdsRole ; swrc:affiliation ; foaf:based_near ; foaf:firstName "Ashutosh Jagdish" , "Ashutosh" ; foaf:lastName "Sharma" ; foaf:made ; foaf:mbox_sha1sum "4b91965e6abe26e6e70d29b1a917d428bbb60d9d" ; foaf:name "Ashutosh Jagdish Sharma" . a foaf:Organization ; rdfs:label "Alibaba Group Research" ; foaf:member ; foaf:name "Alibaba Group Research" . rdf:_1 ; rdf:_2 . a swc:Presenter ; rdfs:label "Presenter of Social Status and Role Analysis of Palin's Email Network" ; swc:heldBy ; swc:isRoleAt . a swc:Chair ; rdfs:label "devchair" , "dev chair" ; swc:heldBy , ; swc:isRoleAt . a foaf:Person ; rdfs:label "Javier D.

Graph simulation has been adopted for pattern matching to reduce the complexity and capture the need of novel applications. In light of the rapid development of the Web and social networks, data is typically distributed over multiple machines. Hence a natural question raised is how to evaluate graph simulation on distributed data. To our knowledge, no such distributed algorithms are in place yet. This paper settles this question by providing evaluation algorithms and optimizations for graph simulation in a distributed setting. (1) We study the impacts of components and data locality on the evaluation of graph simulation. (2) We give an analysis of a large class of distributed algorithms for graph simulation captured by a message-passing model. We also identify three complexity measures: visit times, makespan and data shipment, for the analyses of these distributed algorithms, and show that these measures are controversial with each other. (3) We propose distributed algorithms and optimization techniques which exploit the properties of graph simulation and the analyses of distributed algorithms.

A micro-blogging social network must provide capabilities for users to (i) publish, (ii) follow and (iii) search. Our retrieval mechanism is based on a probably approximately correct (PAC) search architecture in which a query is sent to a fixed number of nodes in the network. In PAC, the probability of attaining a particular accuracy is a function of the number of nodes queried (fixed) and the replication rate of documents (micro-blog). Publishing a micro-blog then becomes a matter of replicating the micro-blog to the required number of random nodes without any central coordination. To solve this, we use techniques from the field of rumour spreading (gossip protocols) to propagate new documents. Our document spreading algorithm is designed such that a document has a very high probability of being copied to only the required number of nodes. Results from simulations performed on networks of 10,000, 100,000 and 500,000 nodes verify our mathematical models.

An important class of such applications is interactive multimedia: games, animations, and interactive visualizations. Unlike many early web applications, these applications are latency sensitive and processing (CPU and graphics) intensive. When demands exceed available resources, application quality (e.g., frame rate) diminishes because it is hard to balance timeliness and utilization. The quality of ambitious web applications is also limited by single-threaded execution prevalent in the Web. Applications need to scale their quality, and thereby scale processing load, based on the resources that are available. We refer to this as scalable quality. DOHA is an execution layer written entirely in JavaScript to enable scalable quality in web applications. DOHA favors important computations with more influence over quality based on hints from application-specific adaptation policies. To utilize widely available multi-core resources, DOHA augments HTML5 web workers with mechanisms to facilitate state management and load-balancing. We evaluate DOHA with an award-winning web-based game. When resources are limited, the modified game has better timing and overall quality. More importantly, quality scales linearly with more cores and the game is playable in challenging scenarios that are beyond the scope of the original game." ; swrc:month "April" ; swrc:year "2012" ; foaf:maker , , . a swc:Presenter ; rdfs:label "Presenter of We Know What @You #Tag: Does the Dual Role Affect Hashtag Adoption?" ; swc:heldBy ; swc:isRoleAt . rdf:_1 ; rdf:_2 . a swrc:InProceedings ; rdfs:label "The Affects of Task Difficulty on Medical Searches" ; swc:isPartOf , ; dce:creator , , ; dce:subject "user study" , "Task difficulty" , "medical searching" , "interactive search behavior" ; dce:title "The Affects of Task Difficulty on Medical Searches" ; bibo:authorList ; swrc:abstract "In this paper, we analyze medical searching behavior performed by a typical medical searcher.

Our research study provides a deep understanding of how task difficulty affects medical search behavior. Non-medical professionals and medical professionals demonstrate similar search behavior when searching on an easy task.

These challenges are difficult to address using current declarative data management frameworks, and we thus propose here a novel such framework, and demonstrate its usefulness in expressing different aspects in the data management of Trivia-like games.

However, most of the research in E-Learning has been focusing on creating a variety of metadata formats and environments for the exchange of educational resources. This has led to a fragmented landscape of Web standards and approaches. In the meantime, the Semantic Web has redefined itself throughout the last years as a Web of “Linked Data”. That was achieved by establishing principles together with a technology stack aimed at facilitating these principles. The huge success and widespread adoption of the Linked Data approach has led to the availability of vast amounts of public data such as DBPedia, WordNet RDF or the data.gov.uk initiative. To this end, the Linked Data movement is also supporting the exposure of large amounts of reusable data and resources, ranging from domain-specific expert vocabularies to, for instance, data about cultural heritage (e.g., the Europeana dataset), which has the potential to fundamentally aid and transform the production, delivery and consumption of educational services and content.

In direct selling, producers can sell the products directly to the consumers without having to go through a cascade of wholesalers. Through direct selling, it is possible to sell the products in a more efficient and economic manner. Motivated by this idea, we propose a target-selecting independent cascade (TIC) model, in which during influence propagation each active node can give up to attempt to influence some neighboring nodes, named victims, who are hard to affect, and try to activate friends of its friends, termed destinations, who could have higher potential to increase the influence spread. The next question to ask is that given a social network and a set of seeds for influence propagation under TIC model, how to effectively select targets (i.e., victims and destinations) for the attempts of activation during propagation to boost the influence spread. We propose and evaluate three heuristics for the target selection. Experiments show that selecting targets based on influence probability between nodes have the highest boost of influence spread." ; swrc:year "2012" ; foaf:maker , , . a foaf:Organization ; rdfs:label "National Technical University of Athens" ; foaf:member ; foaf:name "National Technical University of Athens" . a foaf:Organization ; rdfs:label "UC Davis" ; foaf:member ; foaf:name "UC Davis" . a event:Event , swc:TalkEvent ; rdfs:label "Paper presentation: Not Yet Available" ; swc:hasLocation ; swc:hasRelatedDocument ; swc:hasRole ; swc:isSubEventOf , ; event:agent ; event:place ; icaltzd:location ; icaltzd:summary "Paper presentation: Not Yet Available" . a foaf:Person ; rdfs:label "Eni Mustafaraj" ; swc:holdsRole ; foaf:firstName "Eni" ; foaf:lastName "Mustafaraj" ; foaf:mbox_sha1sum "f127a4cc66897e67f30a8c7ac612665425e6ddad" ; foaf:name "Eni Mustafaraj" . a foaf:Organization ; rdfs:label "IISAS" ; foaf:member ; foaf:name "IISAS" . a event:Event , swc:TalkEvent ; rdfs:label "Paper presentation: The Affects of Task Difficulty on Medical Searches" ; swc:hasLocation ; swc:hasRelatedDocument ; swc:hasRole ; swc:isSubEventOf , ; event:agent ; event:place ; icaltzd:location ; icaltzd:summary "Paper presentation: The Affects of Task Difficulty on Medical Searches" . a foaf:Organization ; rdfs:label "UNC-Chapel Hill" ; foaf:member ; foaf:name "UNC-Chapel Hill" . a foaf:Person ; rdfs:label "Ching Man Au Yeung" ; swc:holdsRole ; swrc:affiliation ; foaf:based_near ; foaf:firstName "Ching Man" ; foaf:lastName "Au Yeung" ; foaf:mbox_sha1sum "3864faf51fa80c3a0378f16a6ff66a86e2164dfd" ; foaf:name "Ching Man Au Yeung" . rdf:_1 ; rdf:_2 ; rdf:_3 . a swrc:InProceedings ; rdfs:label "Risk-aware Revenue Maximization in Display Advertising" ; swc:isPartOf ; dce:creator , ; dce:subject "display advertising" , "revenue maximization" , "factorial pricing experiment" ; dce:title "Risk-aware Revenue Maximization in Display Advertising" ; bibo:authorList ; swrc:abstract "Display advertising is the graphical advertising on the World Wide Web (WWW) that appears next to content on Web pages, instant messaging (IM) applications, email, etc. Over the past decade, display ads have evolved from simple banner and pop-up ads to include various combinations of text, images, audio, video, and animations. As a market segment, display continues to show substantial growth potential, as evidenced by companies such as Microsoft, Yahoo, and Google actively vying for market share. As a sales process, display ads are typically sold in packages, the result of negotiations between sales and advertising agents. A key component to any successful business model in display advertising is sound pricing. Key objectives for on-line publishers (e.g. Amazon, YouTube, CNN) are maximizing revenue while managing their available inventory appropriately, and pricing must reflect these considerations. This paper addresses the problem of maximizing revenue by adjusting prices of display inventory. We cast this as an inventory allocation problem. Our formal objective (a) maximizes expected revenue, while (b) taking into account the opportunity costs of non-sold inventory; (a) and (b) define the primal and dual optimization programs. The major unknown for optimizing revenue in display environment is how the demand for display ads changes to prices, the classical demand curve. This we address directly, by way of a factorial pricing experiment. This enables us to estimate the gradient of the revenue function with respect to inventory prices. Overall, the result is a principled, risk-aware, and empirically efficient methodology.

The design of mechanisms to create effective teams is a key research challenge. Being part of a team requires being able to communicate effectively with other teammates and complementing each other's skills. In this paper, we study the problem of online team formation. We consider a setting in which people possess different skills and compatibility among potential team members is modeled by a social network. A sequence of tasks arrives in an online fashion, and each task requires a specific set of skills. The goal is to form a new team upon arrival of each task, so that (i) each team possesses all skills required by the task, (ii) each team has small communication overhead, and (iii) the workload of performing the tasks is balanced among people in the fairest possible way. We propose efficient algorithms that address all these requirements: our algorithms form teams that always satisfy the required skills, provide approximation guarantees with respect to team communication overhead, and they are online-competitive with respect to load balancing. Experiments performed on collaboration networks among film actors and scientists, confirm that our algorithms are successful at balancing these conflicting requirements. This is the first paper that simultaneously addresses all these aspects.

Guided and constrained by an ontology, ORN transfers the rich semantics in the ontology to image objects and the relations between them, while maintaining semantic consistency (e.g., a soccer player can kick a soccer ball, but cannot ride it).

Selecting a (near-)optimal set of services for a composition in terms of QoS is crucial when many functionally equivalent services are available. With the advent of Cloud Computing, both the number of such services and their distribution across the network is rising rapidly, increasing the impact of the network on the QoS of such compositions. Despite this, current approaches do not differentiate between the QoS of services themselves and the QoS of the network. Therefore, the computed latency differs substantially from the actual latency, resulting in suboptimal QoS for service compositions in the cloud. Thus, we propose a network-aware approach that handles the QoS of services and the QoS of the network independently. First, we build a network model in order to estimate the network latency between arbitrary services. Our selection algorithm then leverages this model to find compositions that will result in a low latency given an employed execution policy. In our evaluation, we show that our approach efficiently computes compositions with much lower latency than current approaches." ; swrc:month "April" ; swrc:year "2012" ; foaf:maker , , . a swc:Presenter ; rdfs:label "Presenter of Dynamic Selection of Activation Targets to Boost the Influence Spread in Social Networks" ; swc:heldBy ; swc:isRoleAt . a foaf:Person ; rdfs:label "Paul Bennett" ; swc:holdsRole , , ; swrc:affiliation ; foaf:based_near , ; foaf:firstName "Paul" ; foaf:lastName "Bennett" ; foaf:made ; foaf:mbox_sha1sum "57c4b4c3a7456d3080bc026287c25a5f6191b530" , "e005ddcf1901d6f41a2e553133b8152ba9025c57" ; foaf:name "Paul Bennett" . a swc:Presenter ; rdfs:label "Presenter of SnoopyTagging: Recommending Contextualized Tags to Increase the Quality and Quantity of Meta-Information" ; swc:heldBy ; swc:isRoleAt . a event:Event , swc:TalkEvent ; rdfs:label "Paper presentation: StormRider: Harnessing ``Storm' for Social Networks" ; swc:hasLocation ; swc:hasRelatedDocument ; swc:hasRole ; swc:isSubEventOf , ; event:agent ; event:place ; icaltzd:location ; icaltzd:summary "Paper presentation: StormRider: Harnessing ``Storm' for Social Networks" . a swc:TrackEvent ; rdfs:label "www 2012 PhD symposium" ; swc:hasAcronym "www2012PHDsymposium" ; swc:hasRelatedDocument ; swc:hasRole , ; swc:isSubEventOf ; icaltzd:url ; foaf:homepage . a foaf:Person ; rdfs:label "Cosma Shalizi" ; swc:holdsRole ; swrc:affiliation ; foaf:based_near ; foaf:firstName "Cosma" ; foaf:lastName "Shalizi" ; foaf:mbox_sha1sum "2d9f471e361cfd024df5e9b76c34670c363ebdf6" ; foaf:name "Cosma Shalizi" . a foaf:Person ; rdfs:label "Xiaofeng Wang" ; swc:holdsRole ; swrc:affiliation ; foaf:based_near ; foaf:firstName "Xiaofeng" ; foaf:lastName "Wang" ; foaf:mbox_sha1sum "6c56a748c6aeb596db979224aa99e0f35b6dce16" ; foaf:name "Xiaofeng Wang" . a foaf:Person ; rdfs:label "Yagil Engel" ; swc:holdsRole ; swrc:affiliation ; foaf:based_near ; foaf:firstName "Yagil" ; foaf:lastName "Engel" ; foaf:mbox_sha1sum "1500aa661f2037581660b4485826902746c2a5e1" ; foaf:name "Yagil Engel" . a swrc:InProceedings ; rdfs:label "ACE: An Adaptive CSS Engine for Web Pages and Web-based Applications" ; swc:isPartOf , ; dce:creator ; dce:subject "Implicit Interaction" , "Event Tracking" , "Adaptive Interfaces" ; dce:title "ACE: An Adaptive CSS Engine for Web Pages and Web-based Applications" ; bibo:authorList ; swrc:abstract "ACE is a system that tailors web interfaces to the users' behavior without requiring end user intervention.

Users in SNS may be interested in tracking an individual’s frequent and representative temporal behaviors. This inspires us to propose a new problem of frequent temporal social behavior search. Given a structural query with associated temporal labels, how to find the instances with matched structure and temporal clues in a heterogeneous network? In this paper, we propose a Temporal Social Behavior Search (TSBS) to achieve such query search. In our TSBS, a query can be (a) a simple structure, (b) a structure with partially assigned individuals, or (c) a structure with assigned individuals and temporal label sequence. Our TSBS consists of two parts: offline mining, and online matching.

As such, most advertisers employ {\\em bidding agents} to submit bids on their behalf. The architecture of such agents typically has (1) an offline optimization phase which incorporates the bidder's knowledge about the market and (2)  an online bidding strategy which simply executes the offline strategy. The online strategy is typically highly dependent on both supply and expected price distributions, both of which are forecast using traditional machine learning methods. In this work we investigate the optimum strategy of the bidding agent when faced with incorrect forecasts. At a high level, the agent can invest resources in improving the forecasts, or can tighten the loop between successive offline optimization cycles in order to detect errors more quickly. We show analytically that the latter strategy, while simple, is extremely effective in dealing with forecast errors, and confirm this finding with experimental evaluations." ; swrc:month "April" ; swrc:year "2012" ; foaf:maker , , . a foaf:Organization ; rdfs:label "Instituto de Fìsica Interdisciplinar y Sistemas Complejos IFISC (CSIC-UIB), Palma de Mallorca" ; foaf:member ; foaf:name "Instituto de Fìsica Interdisciplinar y Sistemas Complejos IFISC (CSIC-UIB), Palma de Mallorca" . a foaf:Person ; rdfs:label "Georges Gouriten" ; swc:holdsRole ; swrc:affiliation ; foaf:based_near ; foaf:firstName "Georges" ; foaf:lastName "Gouriten" ; foaf:made ; foaf:mbox_sha1sum "539f5ad4338ab5e5f774fbaa39196a9537561794" ; foaf:name "Georges Gouriten" . a event:Event , swc:TalkEvent ; rdfs:label "Paper presentation: Data Extraction from Web Pages Based on Structural-Semantic Entropy" ; swc:hasLocation ; swc:hasRelatedDocument ; swc:hasRole ; swc:isSubEventOf , ; event:agent ; event:place ; icaltzd:location ; icaltzd:summary "Paper presentation: Data Extraction from Web Pages Based on Structural-Semantic Entropy" . a foaf:Person ; rdfs:label "Frank Leymann" ; swc:holdsRole ; swrc:affiliation ; foaf:based_near ; foaf:firstName "Frank" ; foaf:lastName "Leymann" ; foaf:mbox_sha1sum "16347d64323354dec32ca0cbc2a78f4e92794a37" ; foaf:name "Frank Leymann" . a swrc:InProceedings ; rdfs:label "TEM: A Novel Perspective to Modeling Content on Microblogs" ; swc:isPartOf , ; dce:creator , ; dce:subject "latent factor models" , "microtext" , "social media" ; dce:title "TEM: A Novel Perspective to Modeling Content on Microblogs" ; bibo:authorList ; swrc:abstract "In recent times, microblogging sites like Facebook and Twitter have gained a lot of popularity. Millions of users world wide have been using these sites to post about topics that interest them and also to voice their opinions on several current events. Valuable business, social insights can be obtained by analyzing the content on these sites. The microtextual nature of the content, continuously evolving themes underlying the data and the scale of the data hosted on these sites emphasize the need for novel text analysis algorithms which can take advantage of such content characteristics. In this paper, we present a novel non-parametric probabilistic model called Theme-Event Model (TEM) for analyzing the content on microblogs. We also describe an online gibbs-sampling based inference algorithm for this model that enables its usage on large scale data. Experimentation carried out on real world data extracted from Facebook and Twitter demonstrates the efficacy of the proposed approach for characterizing content on microblogs." ; swrc:year "2012" ; foaf:maker , . a foaf:Organization ; rdfs:label "Aalborg University" ; foaf:member ; foaf:name "Aalborg University" . a foaf:Person ; rdfs:label "Laurent Flory" ; swc:holdsRole ; swrc:affiliation ; foaf:based_near ; foaf:firstName "Laurent" ; foaf:lastName "Flory" ; foaf:name "Laurent Flory" . a foaf:Person ; rdfs:label "Luca Becchetti" ; swrc:affiliation ; foaf:based_near ; foaf:firstName "Luca" ; foaf:lastName "Becchetti" ; foaf:made ; foaf:mbox_sha1sum "05af8ef2291ca2e8489a0d0c274979dbca875bf3" ; foaf:name "Luca Becchetti" . rdf:_1 ; rdf:_2 . a foaf:Person ; rdfs:label "Intagorn Suradej" ; swrc:affiliation ; foaf:based_near ; foaf:made ; foaf:mbox_sha1sum "8f44f2e5d21c614e4d6db675e78e24f42a48b3ba" ; foaf:name "Intagorn Suradej" . a foaf:Person ; rdfs:label "Tasneem Brutch" ; swrc:affiliation ; foaf:based_near ; foaf:firstName "Tasneem" ; foaf:lastName "Brutch" ; foaf:made ; foaf:mbox_sha1sum "d9f62c8f128e0bdca68eb910add5b101cfebb02f" ; foaf:name "Tasneem Brutch" . a foaf:Person ; rdfs:label "Thomas Roessler" ; swc:holdsRole ; swrc:affiliation ; foaf:based_near ; foaf:firstName "Thomas" ; foaf:lastName "Roessler" ; foaf:mbox_sha1sum "6ae83a26182a5884898e304a434861d4bd150919" ; foaf:name "Thomas Roessler" . a foaf:Person ; rdfs:label "Daniel Gerber" ; swrc:affiliation ; foaf:based_near ; foaf:firstName "Daniel" ; foaf:lastName "Gerber" ; foaf:made ; foaf:mbox_sha1sum "80f77e0f6c75ee8c3f3b84ba1e52f27f849d9e0d" ; foaf:name "Daniel Gerber" . a foaf:Organization ; rdfs:label "Sapienza Universita' di Roma" ; foaf:member , ; foaf:name "Sapienza Universita' di Roma" . a foaf:Person ; rdfs:label "James R.

Latent in these content collections are observations of the world: each photo is a visual snapshot of what the world looked like at a particular point in time and space, for example, while each tweet is a textual expression of the state of a person and their environment. Aggregating together these observations across millions of social sharing users could lead to new techniques for large-scale monitoring of the state of the world and how it is changing over time. In this paper we step towards that goal, showing that by analyzing the tags and image features of geo-tagged, time-stamped photos we can measure and quantify the occurrence of ecological phenomena including ground snow cover, snow fall and vegetation density. We compare several techniques for dealing with the large degree of noise in the dataset, and show how machine learning can be used to reduce errors caused by misleading tags and ambiguous visual content. We evaluate the accuracy of these techniques by comparing to ground truth data collected both by surface stations and by Earth-observing satellites. Besides the immediate application to ecology, our study gives insight into how to accurately crowd-source other types of information from large, noisy social sharing datasets." ; swrc:month "April" ; swrc:year "2012" ; foaf:maker , , , . rdf:_1 ; rdf:_2 ; rdf:_3 ; rdf:_4 ; rdf:_5 . a foaf:Organization ; rdfs:label "HP Research Labs India" ; foaf:member ; foaf:name "HP Research Labs India" . a foaf:Organization ; rdfs:label "Arizona State University, Tempe, USA" ; foaf:member ; foaf:name "Arizona State University, Tempe, USA" . a foaf:Person ; rdfs:label "JavierD.

Hence targeting potential converters is an important problem to boost campaign performance. This is often accomplished by marketers who target users based on behavioral, demographic, contextual, geographic, search, social, purchase-based, lifestye, survey-based, and other information. Such a process is manual and subjective, it often fails to utilize the full potential of targeting. In this paper we show that by using previous conversion data on campaigns along with campaign meta-data, we can combine disparate user information in a principled way to target converters for campaigns. At the heart of our approach is a factor model that estimates the affinity of each user feature to a campaign using historical conversion data. In fact, our approach allows the estimation of campaign factors through campaign features alone and hence works well for new campaigns. Through extensive experiments, we show the superiority of our factor model approach relative to several other baselines." ; swrc:month "April" ; swrc:year "2012" ; foaf:maker , , . a foaf:Person ; rdfs:label "Yorgos Mamakis" ; swc:holdsRole ; swrc:affiliation ; foaf:firstName "Yorgos" ; foaf:lastName "Mamakis" ; foaf:mbox_sha1sum "53fe1e2778ee3b2d7680ced4afa0f69e9a8c1829" ; foaf:name "Yorgos Mamakis" . a event:Event , swc:TalkEvent ; rdfs:label "Paper presentation: On the Analysis of Cascading Style Sheets" ; swc:hasLocation ; swc:hasRelatedDocument ; swc:hasRole ; swc:isSubEventOf , ; event:agent ; event:place ; icaltzd:location ; icaltzd:summary "Paper presentation: On the Analysis of Cascading Style Sheets" . a swrc:InProceedings ; rdfs:label "Practical End-to-End Web Content Integrity" ; swc:isPartOf ; dce:creator , , , , ; dce:subject "caching" , "content integrity" , "web security" ; dce:title "Practical End-to-End Web Content Integrity" ; bibo:authorList ; swrc:abstract "Widespread growth of open wireless hotspots has made it easy to carry out man-in-the-middle attacks and impersonate web sites. Although HTTPS can be used to prevent such attacks, its universal adoption is hindered by its performance cost and its inability to leverage caching at intermediate servers (such as CDN servers and caching proxies) while maintaining end-to-end security. To complement HTTPS, we revive an old idea from SHTTP, a protocol that offers end-to-end web integrity without confidentiality. We name the protocol HTTPi and give it an efficient design that is easy to deploy for today’s web. In particular, we tackle several previously-unidentified challenges, such as supporting progressive page loading on the client’s browser, handling mixed content, and defining access control policies among HTTP, HTTPi, and HTTPS content from the same domain. Our prototyping and evaluation experience show that HTTPi incurs negligible performance overhead over HTTP, can leverage existing web infrastructure such as CDNs or caching proxies without any modifications to them, and can make many of the mixed-content problems in existing HTTPS web sites easily go away. Based on this experience, we advocate browser and web server vendors to adopt HTTPi." ; swrc:month "April" ; swrc:year "2012" ; foaf:maker , , , , . a foaf:Person ; rdfs:label "Martin Bürgler" ; swrc:affiliation ; foaf:based_near ; foaf:made ; foaf:mbox_sha1sum "04347d13b1242300c324a2fb3cf284be2af15132" ; foaf:name "Martin Bürgler" . a foaf:Organization ; rdfs:label "Upenn" ; foaf:member ; foaf:name "Upenn" . a foaf:Organization ; rdfs:label "IDIAP" ; foaf:member ; foaf:name "IDIAP" . rdf:_1 ; rdf:_2 ; rdf:_3 . a foaf:Person ; rdfs:label "Irwin King" ; swc:holdsRole ; foaf:based_near ; foaf:firstName "Irwin" ; foaf:lastName "King" ; foaf:name "Irwin King" . a swc:Presenter ; rdfs:label "Presenter of Information Integration Over Time in Unreliable and Uncertain Environments" ; swc:heldBy ; swc:isRoleAt . a foaf:Organization ; rdfs:label "Harvard Business School" ; foaf:member ; foaf:name "Harvard Business School" . a foaf:Organization ; rdfs:label "School of Engineering, University of California, Santa Cruz" ; foaf:member ; foaf:name "School of Engineering, University of California, Santa Cruz" . rdf:_1 ; rdf:_2 . a foaf:Person ; rdfs:label "Thomas Muders" ; swrc:affiliation ; foaf:based_near ; foaf:made ; foaf:mbox_sha1sum "46c5d28a7b3ae071afc43f2583caa500778d5c43" ; foaf:name "Thomas Muders" . a swrc:InProceedings ; rdfs:label "How Far Can Client-Only Solutions Go for Mobile Browser Speed?" ; swc:isPartOf ; dce:creator , , , ; dce:subject "browser" , "speed" , "mobile" ; dce:title "How Far Can Client-Only Solutions Go for Mobile Browser Speed?" ; bibo:authorList ; swrc:abstract "Mobile browser is known to be slow because of the bottleneck in resource loading. Client-only solutions to improve resource loading are attractive because they are immediately deployable, scalable, and secure. We present the first publicly known treatment of client-only solutions to understand how much they can improve mobile browser speed without infrastructure support. Leveraging an unprecedented set of web usage data collected from 24 iPhone users continuously over one year, we examine the three funda-mental, orthogonal approaches a client-only solution can take: caching, prefetching, and speculative loading, which is first pro-posed and studied in this work. Speculative loading predicts and speculatively loads the subresources needed to open a web page once its URL is given. We show that while caching and prefetching are highly limited for mobile browsing, speculative loading can be significantly more effective. Empirically, we show that client-only solutions can improve the browser speed by about 1.4 second on average for web sites visited by the 24 iPhone users. We also report the design, realization, and evaluation of speculative loading in a WebKit-based browser called Tempo. On average, Tempo can reduce browser delay by 1 second (~20%)." ; swrc:month "April" ; swrc:year "2012" ; foaf:maker , , , . a event:Event , swc:TalkEvent ; rdfs:label "Paper presentation: Latent Contextual Indexing of Annotated Documents" ; swc:hasLocation ; swc:hasRelatedDocument ; swc:hasRole ; swc:isSubEventOf , ; event:agent ; event:place ; icaltzd:location ; icaltzd:summary "Paper presentation: Latent Contextual Indexing of Annotated Documents" . a foaf:Person ; rdfs:label "Jagadeesh Jagarlamudi" ; swc:holdsRole ; swrc:affiliation , ; foaf:based_near ; foaf:firstName "Jagadeesh" ; foaf:lastName "Jagarlamudi" ; foaf:made , ; foaf:mbox_sha1sum "552d0bd459c11b4c391c01e082d4a708191da541" ; foaf:name "Jagadeesh Jagarlamudi" . a swc:Presenter ; rdfs:label "Presenter of Outage Detection via Real-time Social Stream Analysis: Leveraging the Power of On-line Complaints" ; swc:heldBy ; swc:isRoleAt . a swc:ProgrammeCommitteeMember ; rdfs:label "Network track committee member" ; swc:heldBy , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , ; swc:isRoleAt . rdf:_1 ; rdf:_2 ; rdf:_3 . a foaf:Person ; rdfs:label "Yunhua Hu" ; swc:holdsRole ; foaf:firstName "Yunhua" ; foaf:lastName "Hu" ; foaf:mbox_sha1sum "c91bebe26a5086793701bbbf08ee1000d38d4d59" ; foaf:name "Yunhua Hu" . a foaf:Organization ; rdfs:label "National Universtiy of Defense Technology" ; foaf:member , ; foaf:name "National Universtiy of Defense Technology" . a foaf:Organization ; rdfs:label "Telecom ParisTech" ; foaf:member ; foaf:name "Telecom ParisTech" . a foaf:Organization ; rdfs:label "Alcatel-Lucent Bell Labs France" ; foaf:member , , , , ; foaf:name "Alcatel-Lucent Bell Labs France" . a foaf:Person ; rdfs:label "Lyndon Nixon" ; swrc:affiliation ; foaf:based_near ; foaf:firstName "Lyndon" ; foaf:lastName "Nixon" ; foaf:made ; foaf:mbox_sha1sum "fedfee89e4699ebbd40cfd1aa1c44a1fd0220d7d" ; foaf:name "Lyndon Nixon" . a foaf:Person ; rdfs:label "Nicola Perra" ; swc:holdsRole ; swrc:affiliation ; foaf:based_near ; foaf:firstName "Nicola" ; foaf:lastName "Perra" ; foaf:mbox_sha1sum "a3687c513c3c133f5ca010973bfa44e5cc4abbcd" ; foaf:name "Nicola Perra" . a event:Event , swc:PanelEvent ; rdfs:comment """

Cross-lingual links in Wikipedia connect equivalent articles written in different languages, which have been widely exploited in various applications. However, the available articles in different languages are quite unbalanced. For example, up to now the articles in English Wikipedia has reached 3.8 million, while the available articles in Chinese Wikipedia are less than half million. On the other hand, there are more than 3.9 million articles in Baidu Baike and Hudong, another two popular encyclopedias in Chinese. Therefore, finding cross-lingual links between Wikipedia and these Wiki knowledge bases can largely enrich the cross-lingual knowledge. In this paper, we formalize the cross-lingual knowledge linking problem into a linkage factor graph model. Features are defined according to some interesting observations. Experiments on the Wikipedia data set show that our approach can achieve high precision 85.80% with a recall of 88.10%. In addition, we find 202,141 new cross-lingual links between English Wikipedia and Baidu Baike using the proposed approach, which are almost as many as existing ones in Wikipedia." ; swrc:month "April" ; swrc:year "2012" ; foaf:maker , , , . a foaf:Person ; rdfs:label "Gui-Rong Xue" ; swc:holdsRole ; swrc:affiliation ; foaf:based_near ; foaf:firstName "Gui-Rong" ; foaf:lastName "Xue" ; foaf:mbox_sha1sum "ce2dee14cea7fdef37830f1e2ee3b70fd2694a44" ; foaf:name "Gui-Rong Xue" . a swc:Presenter ; rdfs:label "Presenter of Towards Multiple Identity Detection in Social Networks" ; swc:heldBy ; swc:isRoleAt . a swc:Presenter ; rdfs:label "Presenter of Active Objects: Actions for Entity-Centric Search" ; swc:heldBy ; swc:isRoleAt . a event:Event , swc:TalkEvent ; rdfs:label "Paper presentation: Chinese News Event 5W1H Semantic Elements Extraction for Event Ontology Population" ; swc:hasLocation ; swc:hasRelatedDocument ; swc:hasRole ; swc:isSubEventOf , ; event:agent ; event:place ; icaltzd:location ; icaltzd:summary "Paper presentation: Chinese News Event 5W1H Semantic Elements Extraction for Event Ontology Population" . a foaf:Person ; rdfs:label "Jan Carlson" ; swrc:affiliation ; foaf:based_near ; foaf:firstName "Jan" ; foaf:lastName "Carlson" ; foaf:made ; foaf:mbox_sha1sum "0fe6a9d76c2a2812414d4531136ce866c45fbfbe" ; foaf:name "Jan Carlson" . a foaf:Organization ; rdfs:label "University of Illinois at Urbana Champaign" , "University of Illinois at Urbana-Champaign" , "University of Illnois at Urbana-Champaign" ; foaf:member , , , , , ; foaf:name "University of Illinois at Urbana Champaign" , "University of Illnois at Urbana-Champaign" , "University of Illinois at Urbana-Champaign" . a foaf:Person ; rdfs:label "Francesco Nucci" ; swc:holdsRole ; swrc:affiliation ; foaf:firstName "Francesco" ; foaf:lastName "Nucci" ; foaf:mbox_sha1sum "90bcb9a16d29a6b477d3dc96ebba841adf67ca70" ; foaf:name "Francesco Nucci" . a foaf:Organization ; rdfs:label "Siemens" ; foaf:member ; foaf:name "Siemens" . a foaf:Organization ; rdfs:label "LIRIS" ; foaf:member , , ; foaf:name "LIRIS" . a event:Event , swc:PanelEvent ; rdfs:comment """Panelists

While network community detection has been ubiquitous, the task of collecting complete network data remains challenging in many real-world applications. Usually the collected network is incomplete with most of the edges missing. Commonly, in such networks, all nodes with attributes are available while only the edges within a few local regions of the network can be observed. In this paper, we study the problem of detecting communities in incomplete information networks with missing edges. We first learn a distance metric to reproduce the link-based distance between nodes from the observed edges in the local information regions. We then use the learned distance metric to estimate the distance between any pair of nodes of the network. A hierarchy clustering algorithm DSHRINK, is proposed to detect communities within the incomplete information networks. Empirical studies on real-world information networks demonstrate that our proposed method can effectively detect community structures within incomplete information networks." ; swrc:month "April" ; swrc:year "2012" ; foaf:maker , , , , , . a foaf:Person ; rdfs:label "Patrick Gallinari" ; swrc:affiliation ; foaf:based_near ; foaf:made ; foaf:mbox_sha1sum "65a50dd73d26b0260199988200cb0a048ec419e7" ; foaf:name "Patrick Gallinari" . a foaf:Organization ; rdfs:label "ERIC Lab, University of Lyon" ; foaf:member ; foaf:name "ERIC Lab, University of Lyon" . a foaf:Person ; rdfs:label "Fabricio Benevenuto" ; swc:holdsRole ; swrc:affiliation ; foaf:based_near ; foaf:firstName "Fabricio" ; foaf:lastName "Benevenuto" ; foaf:made ; foaf:mbox_sha1sum "3eacd53b7338a73a09490c8853bd9203a4f264b2" ; foaf:name "Fabricio Benevenuto" . a foaf:Organization ; rdfs:label "University of Sheffield" ; foaf:member , , ; foaf:name "University of Sheffield" . a foaf:Person ; rdfs:label "Miel Vander Sande" ; swc:holdsRole ; swrc:affiliation ; foaf:based_near ; foaf:firstName "Miel" ; foaf:lastName "Vander Sande" ; foaf:made ; foaf:mbox_sha1sum "9da436ca83fe1f6c31b15af200be0fee8e29faca" ; foaf:name "Miel Vander Sande" . a swrc:InProceedings ; rdfs:label "Scalable, Flexible and Generic Instant Overview Search" ; swc:isPartOf , ; dce:creator , , ; dce:subject "web search" , "caching" , "instant search" , "entity mining" ; dce:title "Scalable, Flexible and Generic Instant Overview Search" ; bibo:authorList ; swrc:abstract "The last years there is an increasing interest on providing the top search results while the user types a query letter by letter. In this paper we present and demonstrate a family of instant search applications which apart from showing on-the-fly only the top search results, they can show various other kinds of pre-computed aggregated information. This paradigm is more helpful for the end user (in comparison to the classic search-as-you-type), since it can combine autocompletion, search-as-you-type, results clustering, faceted search, entity mining, etc. Furthermore, apart from being helpful for the end user, it is also beneficial for the server's side. However, the instant provision of such services for large number of queries, big amounts of pre-computed information, and large number of concurrent users is challenging. We demonstrate how this can be achieved using very modest hardware. Our approach relies on (a) a partitioned trie-based index that exploits the available main memory and disk, and (b) dedicated caching techniques. We report performance results over a server running on a modest personal computer (with 3 GB main memory) that provides instant services for millions of distinct queries and terabytes of pre-computed information. Furthermore these services are tolerant to user typos and the word order." ; swrc:year "2012" ; foaf:maker , , . a swc:Presenter ; rdfs:label "Presenter of Model News Relatedness through User Comments" ;

bibo:authorList ; swrc:abstract "Did celebrity last longer in 1929, 1992 or 2009? We investigate the phenomenon of fame by mining a collection of news articles that spans the twentieth century, and also perform a side study on a collection of blog posts from the last 10 years. By analyzing mentions of personal names, we measure each person's time in the spotlight, and watch the distribution change from a century ago to a year ago. We expected to find a trend of decreasing durations of fame as news cycles accelerated and attention spans became shorter. Instead, we find a remarkable consistency through most of the period we study. Through a century of rapid technological and societal change, through the appearance of Twitter, communication satellites and the Internet, we do not observe a significant change in typical duration of celebrity. We also study the most famous of the famous, and find different results depending on our method for measuring duration of fame. With a method that may be thought of as measuring a spike of attention around a single narrow news story, we see the same result as before: stories last as long now as they did in 1930. A second method, which may be thought of as measuring the duration of public interest in a person, indicates that famous people's presence in the news is becoming longer rather than shorter, an effect most likely driven by the wider distribution and higher volume of media in modern times. Similar studies have been done with much shorter timescales specifically in the context of information spreading on Twitter and similar social networking site. However, to the best of our knowledge, this is the first massive scale study of this nature that spans over a century of archived data, thereby allowing us to track changes across decades." ; swrc:month "April" ;

This multitude of voicesmakes it more and more important to detect bias and help Internet usersunderstand the background of information sources. Political bias of Web sites,articles, or blog posts is hard to identify straightaway. Manual contentanalysis conducted by experts is the standard way in political and socialscience to detect this bias. In this paper we present an automated approachrelying on methods from information retrieval and corpus statistics to identifybiased vocabulary use. As an example, we analyzed 15 years of parliamentary speechesof the German Bundestag and we investigated whether there is bias towards apolitical party in major national online newspapers and magazines. The results showthat bias exists with respect to vocabulary use and it coincides with humanjudgement." ; swrc:year "2012" ; foaf:maker , , . a swc:Presenter ; rdfs:label "Presenter of Leveraging Interlingual Classification to Improve Web Search" ; swc:heldBy ; swc:isRoleAt . a foaf:Organization ; rdfs:label "SAP AG" ; foaf:member , ; foaf:name "SAP AG" . a foaf:Organization ; rdfs:label "University of Fribourg" ; foaf:member ; foaf:name "University of Fribourg" . a foaf:Person ; rdfs:label "Rushi Bhatt" ; swrc:affiliation ; foaf:based_near ; foaf:firstName "Rushi" ; foaf:lastName "Bhatt" ; foaf:made ; foaf:mbox_sha1sum "99d69c251073a19d938a44eb84cbb336b9fb5ef4" ; foaf:name "Rushi Bhatt" . a swrc:InProceedings ; rdfs:label "Using Community Information to Improve the Precision of Link Prediction Methods" ; swc:isPartOf , ; dce:creator , ; dce:subject "link prediction" , "communities" , "social networks" ; dce:title "Using Community Information to Improve the Precision of Link Prediction Methods" ; bibo:authorList ; swrc:abstract "A great deal of work focuses on analyzing various features of networks; however, network data is often limited and incomplete. Because of this, researchers consider the link prediction problem, which asks the question of which non-existent edges in an incomplete network are most likely to actually exist in the complete network. Classical approaches to this problem compute the `similarity' of two unconnected nodes, and conclude that highly similar nodes are most likely to be connected in the complete network. In this paper, we consider several such similarity-based measures, but supplement the similarity calculations with community information, which may be obtained either from metadata or from community detection algorithms. We show that for many networks, the inclusion of community information improves the accuracy of similarity-based link prediction methods." ; swrc:year "2012" ; foaf:maker , . a swc:Presenter ; rdfs:label "Presenter of Kjing (Mix The Knowledge)" ; swc:heldBy ; swc:isRoleAt . a event:Event , swc:TalkEvent ; rdfs:label "Paper presentation: DOHA: Scalable Real-time Web Applications through Adaptive Concurrent Execution" , "Paper presentation: Document Hierarchies from Text and Links" ; swc:hasLocation , ; swc:hasRelatedDocument ; swc:hasRole ; swc:isSubEventOf , , ; event:agent , ; event:place , ; icaltzd:location , ; icaltzd:summary "Paper presentation: DOHA: Scalable Real-time Web Applications through Adaptive Concurrent Execution" , "Paper presentation: Document Hierarchies from Text and Links" . a foaf:Organization ; rdfs:label "Chinese University of Hong Kong" ; foaf:member ; foaf:name "Chinese University of Hong Kong" . a foaf:Person ; rdfs:label "Sungchan Park" ; swrc:affiliation ; foaf:based_near ; foaf:made ; foaf:mbox_sha1sum "10379a1df07ba2bb1c449ac7a5ca58fe0ce5a0dd" ; foaf:name "Sungchan Park" . a foaf:Person ; rdfs:label "Pinar Donmez" ; swc:holdsRole ; swrc:affiliation , ; foaf:based_near , ; foaf:firstName "Pinar" ; foaf:lastName "Donmez" ; foaf:made ; foaf:mbox_sha1sum "bbd6f8fce7a49f3c28479d234159e4c32d0409c2" ; foaf:name "Pinar Donmez" . a foaf:Person ; rdfs:label "Gideon Dror" ; swrc:affiliation , ; foaf:based_near , ; foaf:firstName "Gideon" ; foaf:lastName "Dror" ; foaf:made , ; foaf:mbox_sha1sum "98e984f2be6dae7b714ad69d499b317fbd8db964" ; foaf:name "Gideon Dror" . a swc:Role ; rdfs:label "Project Manager at Leveraging User-Generated Content" ; swc:heldBy ; swc:isRoleAt . a event:Event , swc:TalkEvent ; rdfs:label "Paper presentation: The Information Workbench as a Self-Service Platform for Developing Linked Data Applications" ; swc:hasLocation ; swc:hasRelatedDocument ; swc:hasRole ; swc:isSubEventOf , ; event:agent ; event:place ; icaltzd:location ; icaltzd:summary "Paper presentation: The Information Workbench as a Self-Service Platform for Developing Linked Data Applications" . a foaf:Organization ; rdfs:label "INSA / IRISA" ; foaf:member ; foaf:name "INSA / IRISA" . a foaf:Organization ; rdfs:label "Erasme" ; foaf:member ; foaf:name "Erasme" . a foaf:Person ; rdfs:label "Emilee Rader" ; swc:holdsRole ; swrc:affiliation ; foaf:firstName "Emilee" ; foaf:lastName "Rader" ; foaf:mbox_sha1sum "ef48dca420b13600917d891580a13e0c4bedef03" ; foaf:name "Emilee Rader" . a foaf:Organization ; rdfs:label "European Commission" ; foaf:member ; foaf:name "European Commission" . a foaf:Person ; rdfs:label "Vlad Stirbu" ; swc:holdsRole ; swrc:affiliation ; foaf:based_near ; foaf:firstName "Vlad" ; foaf:lastName "Stirbu" ; foaf:made ; foaf:mbox_sha1sum "b3933dd733655e749cbb8dbfb03e97f27b679342" ; foaf:name "Vlad Stirbu" . a foaf:Organization ; rdfs:label "Institute of Computer Science, FORTH" ; foaf:member , ; foaf:name "Institute of Computer Science, FORTH" . a swrc:InProceedings ; rdfs:label "Learning and Predicting Behavioral Dynamics on the Web" ; swc:isPartOf ; dce:creator , , , , , ; dce:subject "Web dynamics and search" , "Temporal data analysis" , "Temporal User Behavior prediction" , "Query log mining" ; dce:title "Learning and Predicting Behavioral Dynamics on the Web" ; bibo:authorList ; swrc:abstract "Users’ behaviors on theWeb shift over time in terms of pages of interest to users, queries issued to a search engine, and the underlying informational goals behind the queries.

We also explore other dynamics of the Web, such as the detection of periodicities and surprises. We develop a learning procedure that can be used to construct models of users’ behaviors based on features of present and histor- ical behaviors.

Apart from established collaborative web applications, numerous web editors lack multi-user support even though they are suitable for collaborative work. Enhancing these single-user editors with shared editing capabilities is a costly endeavor since the implementation of a collaboration infrastructure (accommodating conflict resolution, document synchronization, etc.) is required. In this paper, we present a generic transformation approach capable of converting single-user web editors into multi-user editors. Since our approach only requires the configuration of a generic collaboration infrastructure (GCI), the effort to inject shared editing support is significantly reduced in contrast to conventional implementation approaches neglecting reuse. We also report on experimental results of a user study showing that converted editors meet user requirements with respect to software and collaboration qualities. Moreover, we define the characteristics that editors must adhere to in order to leverage the GCI." ; swrc:month "April" ; swrc:year "2012" ; foaf:maker , , , . a foaf:Person ; rdfs:label "Zachary O.

In an annotation study conducted over a random sample of user query sessions, we found that a large proportion of queries in query logs involve actions on entities, calling for an automatic approach to identifying relevant actions for entity-bearing queries. In this paper, we pose the problem of finding actions that can be performed on entities as the problem of doing probabilistic inference in a graphical model that captures how an entity bearing query is generated. We design models of increasing complexity that capture latent factors such as entity type and intended actions that determine how a user writes a query in a search box, and the URL that they click on. Given a large collection of real-world queries and clicks from a commercial search engine, the models are learned efficiently through maximum likelihood estimation using an EM algorithm. Given a new query, probabilistic inference enables recommendation of a set of pertinent actions and hosts. We propose an evaluation methodology for measuring the relevance of our recommended actions, and show empirical evidence of the quality and the diversity of the discovered actions." ; swrc:month "April" ; swrc:year "2012" ; foaf:maker , , , , . a foaf:Person ; rdfs:label "Prabhakar Raghavan" ; swrc:affiliation ; foaf:based_near ; foaf:firstName "Prabhakar" ; foaf:lastName "Raghavan" ; foaf:made ; foaf:mbox_sha1sum "a9dbc5f588af21b95f49e4d09c85efb8715cb894" ; foaf:name "Prabhakar Raghavan" . a foaf:Organization ; rdfs:label "University of Oxford Computing Laboratory" ; foaf:member ; foaf:name "University of Oxford Computing Laboratory" . a swc:Presenter ; rdfs:label "Presenter of Google Image Swirl; A Large-Scale Content-Based Image Visualization System" ; swc:isRoleAt . a swc:Chair ; rdfs:label "Behaviour track chair" ; swc:heldBy , , ; swc:isRoleAt . a foaf:Person ; rdfs:label "Steven C.H.

Most existing means rely on validators that check syntactic rules, and on runtime debuggers that check the behavior of a CSS style sheet on a particular document instance. However, the aim of most style sheets is to be applied to an entire set of documents, usually defined by some schema. To this end, a CSS style sheet is usually written w.r.t. a given schema. While usual debugging tools help reducing the number of bugs, they do not ultimately allow to prove properties over the whole set of documents to which the style sheet is intended to be applied. We propose a novel approach to fill this lack. We introduce ideas borrowed from the fields of logic and compile-time verification for the analysis of CSS style sheets. We present an original tool based on recent advances in tree logics. The tool is capable of statically detecting a wide range of errors (such as empty CSS selectors and semantically equivalent selectors), as well as proving properties related to sets of documents (such as coverage of styling information), in the presence or absence of schema information. This new tool can be used in addition to existing runtime debuggers to ensure a higher level of quality of CSS style sheets." ; swrc:month "April" ; swrc:year "2012" ; foaf:maker , , . a foaf:Person ; rdfs:label "Aiman Erbad" ; swc:holdsRole ; swrc:affiliation ; foaf:based_near ; foaf:firstName "Aiman" ; foaf:lastName "Erbad" ; foaf:made ; foaf:mbox_sha1sum "ec30812422f527d7a2289d4619f1451cbd8f94d4" ; foaf:name "Aiman Erbad" . a swrc:InProceedings ; rdfs:label "Towards Optimizing the Non-Functional Service Matchmaking Time" ; swc:isPartOf , ; dce:creator , ; dce:subject "optimization" , "service" , "non-functional" , "performance" , "matchmaking" , "constraint programming" , "QoS" , "discovery" ; dce:title "Towards Optimizing the Non-Functional Service Matchmaking Time" ; bibo:authorList ; swrc:abstract "The Internet is moving fast to a new era where million of services and thingswill be available.

The related approaches in service discovery mainly concentrate on exploiting constraint solving techniques for inferring if the user non-functional requirements are satisfiedby the service nonfunctional capabilities. However, as the matchmaking time is proportional to the number of non-functional service descriptions, these approaches fail to fulfill the user request in a timely manner. To this end, two alternative techniques for improving the non-functional service matchmaking time have been developed. The first one is generic as it can handle non-functional servicespecifications containing n-ary constraints, while the second is only applicable tounary-constrained specifications. Both techniques were experimentally evaluated.

In particular, the critical path of a composite Web application, i.e., the execution path in the service composition with the maximum execution time, should be prioritised in cost-effective monitoring as it determines the response time of the Web application. In volatile operating environments, the critical path of a Web application is probabilistic. As such, it is important to estimate the criticalities of the execution paths and the component services, i.e., the probabilities that they are critical, to decide which parts of the system to monitor. In this paper, we propose a novel approach to the identification of Probabilistic Critical Path for Service-based Web Applications (PCP-SWA).

We use network proximity to capture the degree to which people are ``close'' to each other. In addition to standard proximity metrics used in the link prediction task, such as neighborhood overlap, we introduce new metrics that model different types of interactions that take place between people. We study this claim empirically using data about URL forwarding activity on the social media sites Digg and Twitter. We show that structural proximity of two users in the follower graph is related to similarity of their activity, i.e., how many URLs they both forward. We also show that given friends' activity, knowing their proximity to the user can help better predict which URLs the user will forward. We compare the performance of different proximity metrics on the activity prediction task and find that metrics that take into account the attention-limited nature of interactions in social media lead to substantially better predictions." ; swrc:year "2012" ; foaf:maker , , , . rdf:_1 ; rdf:_10 ; rdf:_11 ; rdf:_2 ; rdf:_3 ; rdf:_4 ; rdf:_5 ; rdf:_6 ; rdf:_7 ; rdf:_8 ; rdf:_9 . a event:Event , swc:TalkEvent ; rdfs:label "Paper presentation: Review Spam Detection via Time Series Pattern Discovery" ; swc:hasLocation ; swc:hasRelatedDocument ; swc:hasRole ; swc:isSubEventOf , ; event:place ; icaltzd:location ; icaltzd:summary "Paper presentation: Review Spam Detection via Time Series Pattern Discovery" . a foaf:Person ; rdfs:label "Shu Tao" ; swrc:affiliation ; foaf:based_near ; foaf:firstName "Shu" ; foaf:lastName "Tao" ; foaf:made ; foaf:mbox_sha1sum "6f447c056e52a98948ea93ee5a689e3999fd86af" ; foaf:name "Shu Tao" . a foaf:Person ; rdfs:label "Yuming Lin" ; swrc:affiliation ; foaf:based_near ; foaf:made ; foaf:mbox_sha1sum "fb52dee078deff3b2d4d281366ddf03b5e54783d" ; foaf:name "Yuming Lin" . a swrc:InProceedings ; rdfs:label "A Data-Driven Sketch of Wikipedia Editors" ; swc:isPartOf , ; dce:creator , , ; dce:subject "expertise" , "editors" , "Wikipedia" , "Web usage" ; dce:title "A Data-Driven Sketch of Wikipedia Editors" ; bibo:authorList ; swrc:abstract "Who edits Wikipedia?

The degree to which content is disseminated within the network depends on the connectivity relationships among network nodes. Existing schemes for recommending connections in social networks are based on the number of common neighbors, similarity of user profiles, etc. However, such similarity-based connections do not consider the amount of content discovered. In this paper, we propose novel algorithms for recommending connections that boost content propagation in a social network without compromising on the relevance of the recommendations. Unlike existing work on influence propagation, in our environment, we are looking for edges instead of nodes, with a bound on the number of incident edges per node. We show that the content spread function is not submodular, and develop approximation algorithms for computing a near-optimal set of edges. Through experiments on real-world social graphs such as Flickr and Twitter, we show that our approximation algorithms achieve content spreads that are as much as 90 times higher compared to existing heuristics for recommending connections." ; swrc:month "April" ; swrc:year "2012" ; foaf:maker , , , . a swc:Chair ; rdfs:label "User Inferfaces track chair" ; swc:heldBy , ; swc:isRoleAt . a swc:Presenter ; rdfs:label "Presenter of QUBE: a Quick algorithm for Updating BEtweenness centrality" ; swc:heldBy ; swc:isRoleAt . a foaf:Person ; rdfs:label "Eytan Bakshy" ; swc:holdsRole ; swrc:affiliation ; foaf:based_near ; foaf:firstName "Eytan" ; foaf:lastName "Bakshy" ; foaf:made ; foaf:mbox_sha1sum "01bf16c7410d535de158e70587b3d78ad6f3251b" ; foaf:name "Eytan Bakshy" . a swc:Presenter ; rdfs:label "Presenter of Titan: a System for Effective Web Service Discovery" ; swc:heldBy ; swc:isRoleAt . a foaf:Person ; rdfs:label "Boris Motik" ; swc:holdsRole , ; swrc:affiliation , ; foaf:based_near , ; foaf:firstName "Boris" ; foaf:lastName "Motik" ; foaf:made ; foaf:mbox_sha1sum "d1822505990c7a62874033c9a382d43f94785308" ; foaf:name "Boris Motik" . a foaf:Organization ; rdfs:label "University of Rome \"La Sapienza\"" ; foaf:member ; foaf:name "University of Rome \"La Sapienza\"" . a foaf:Person ; rdfs:label "Christian Sengstock" ; swc:holdsRole ; swrc:affiliation ; foaf:based_near ; foaf:firstName "Christian" ; foaf:lastName "Sengstock" ; foaf:made ; foaf:mbox_sha1sum "95c83a3060897c8bca32f33fcfc9b50f30a52982" ; foaf:name "Christian Sengstock" . rdf:_1 ; rdf:_2 ; rdf:_3 ; rdf:_4 ; rdf:_5 . a swrc:InProceedings ; rdfs:label "Combining Flat and Structured Approaches for Temporal Slot Filling or: How Much to Compress?" ; swc:isPartOf ; dce:creator ; dce:subject "Temporal Slot Filling" , "Temporal Classification" , "Kernel Methods" , "Temporal Aggregation" ; dce:title "Combining Flat and Structured Approaches for Temporal Slot Filling or: How Much to Compress?" ; bibo:authorList ; swrc:abstract "In this paper, we present a hybrid approach to Temporal Slot Filling (TSF) task at NIST TAC Knowledge Base Population (KBP2011) track. Our method decomposes the task into two steps: temporal classification and temporal aggregation. As in many other NLP tasks, a key challenge lies in capturing relations between text elements separated by a long context. We have observed that features derived from a structured text representation can help compressing the context and reducing ambiguity; while surface lexical features are more robust and work better in some cases. Experiments show that both surface and structured approaches outperform some baselines and that proposed hybrid method can further improve the performance significantly.

In this work, we analyze real-life collaborative networks to understand their common characteristics and how information is routed in these networks. Our study shows that the topology of collaborative networks not only exhibits scale-free properties in node degree distribution, but also has other organizational constraints. Furthermore, the number of steps in which information gets routed in these networks follow a power-law distribution too. Based on these observations, we develop a network model that can generate synthetic collaborative networks subject to certain structure constraints. We further design a routing model that emulates task-driven information routing conducted by human beings in a collaborative network. Together, these two models can be used to study the efficiency of information routing in different topological settings of a target collaborative network -- a problem that is important in practice yet difficult to solve without the method proposed in this work." ; swrc:month "April" ; swrc:year "2012" ; foaf:maker , , , , , . rdf:_1 ; rdf:_2 ; rdf:_3 ; rdf:_4 . a foaf:Person ; rdfs:label "Sugato Basu" ; swc:holdsRole ; swrc:affiliation ; foaf:based_near ; foaf:firstName "Sugato" ; foaf:lastName "Basu" ; foaf:mbox_sha1sum "69997c5fc74023081b41438c9016e514e1e39c40" ; foaf:name "Sugato Basu" . a foaf:Organization ; rdfs:label "IBM China Research Lab" ; foaf:member , ; foaf:name "IBM China Research Lab" . a foaf:Person ; rdfs:label "Antonio Pintus" ; swc:holdsRole ; swrc:affiliation ; foaf:based_near ; foaf:firstName "Antonio" ; foaf:lastName "Pintus" ; foaf:made ; foaf:mbox_sha1sum "5f37aaeca620785140c5be51f39f2dc9981b1b11" ; foaf:name "Antonio Pintus" . a foaf:Person ; rdfs:label "David Malone" ; swc:holdsRole ; swrc:affiliation ; foaf:based_near ; foaf:firstName "David" ; foaf:lastName "Malone" ; foaf:made ; foaf:mbox_sha1sum "8238a9da2eaf01cfaf637aecf76ed32672e31290" ; foaf:name "David Malone" . a foaf:Organization ; rdfs:label "Case Western" ; foaf:member ; foaf:name "Case Western" . a foaf:Person ; rdfs:label "Christian Bizer" ; swc:holdsRole ; swrc:affiliation ; foaf:based_near , ; foaf:firstName "Christian" ; foaf:lastName "Bizer" ; foaf:made , ; foaf:mbox_sha1sum "50c02ff93e7d477ace450e3fbddd63d228fb23f3" ; foaf:name "Christian Bizer" . a foaf:Person ; rdfs:label "Jiahui Liu" ; swc:holdsRole ; swrc:affiliation ; foaf:based_near ; foaf:firstName "Jiahui" ; foaf:lastName "Liu" ; foaf:mbox_sha1sum "d782c6c24f770ee647963998b444dc38ea1a70ad" ; foaf:name "Jiahui Liu" . a swc:Presenter ; rdfs:label "Presenter of Semi-structured Semantic Overlay for Information Retrieval in Self-organizing Networks" ; swc:heldBy ; swc:isRoleAt . a foaf:Person ; rdfs:label "Takehiro Tokuda" ; swc:holdsRole ; swrc:affiliation ; foaf:based_near ; foaf:firstName "Takehiro" ; foaf:lastName "Tokuda" ; foaf:mbox_sha1sum "07902c9c92aa12f14733e7acf65c254c5d7a3f50" ; foaf:name "Takehiro Tokuda" . a foaf:Person ; rdfs:label "Pern Hui Chia" ; swrc:affiliation ; foaf:based_near ; foaf:firstName "Pern Hui" ; foaf:lastName "Chia" ; foaf:made ; foaf:mbox_sha1sum "efa98b30d448647d071934cd476aa55617cc41f6" ; foaf:name "Pern Hui Chia" . a swrc:InProceedings ; rdfs:label "GoThere: Travel Suggestions using Geotagged Photos" ; swc:isPartOf , ; dce:creator , , , , ; dce:subject "context aware query" , "photo collections" , "trip planning" ; dce:title "GoThere: Travel Suggestions using Geotagged Photos" ; bibo:authorList ; swrc:abstract "We propose a context and preference aware travel guide that suggests significant tourist destinations to users based on their preferences and current surrounding context using contextualized user-generated contents from the social media repository, i.e., Flickr." ; swrc:year "2012" ; foaf:maker , , , , . a event:Event , swc:WorkshopEvent ; rdfs:comment """

We discuss a case study using a web-based community information management system, then present results regarding the performance of queries over the provenance data gathered by our logic program interpreter.

With the advent of the paradigm of Web 2.0 especially the past 5 years, the concept of image context has further evolved, allowing users to tag their own and other people's pictures. Focusing on tagging, we distinguish between static and dynamic features. The set of static features include textual and visual features, as well as the contextual information. Further, we may identify other features belonging to the social context as a result of the usage within the media sharing applications. Due to their dynamic nature, we call these the dynamic set of features. In this work, we assume that every media uploaded contains both static and dynamic features. In addition, a user may be linked with other users with whom he/she shares common interests. This has resulted in a new series of challenges within the semantic understanding research field.

Previous research has tackled this problem by first forming a catalog of entities from a knowledge base such as Wikipedia and then using this catalog subsequently to disambiguate references in unseen text. However, most of the previously proposed models either do not use all text in the knowledge base thus potentially missing out on discriminative features or do not exploit word-entity proximity to learn high-quality catalogs. In this work, we propose topic models that keep track of the context of every word in the knowledge base so that entities appearing in the same context are more likely to be associated with the word. Thus, our topic models utilize all text present in the knowledge base and help learn high-quality, discerning catalogs. Our models also learn groups of co-occurring entities from the knowledge base thus allowing us to perform collective disambiguation. Unlike most previous topic models, our models are non-parametric and do not require the user to specify how many groups exist in the knowledge base. In experiments performed on an extract of Wikipedia containing almost 60,000 references, our models outperform SVM-based baselines by as much as 18\\% in terms of disambiguation accuracy translating to an increment of almost 11,000 correctly disambiguated references." ; swrc:month "April" ; swrc:year "2012" ; foaf:maker . a event:Event , swc:WorkshopEvent ; rdfs:comment """

This facilitates extending existing metadata about digital resources. However, due to various levels of annotators' expertise, the quality of annotations can vary from excellent to vague. The evaluation and moderation of annotations (be they troll, vague, or helpful) have not been sufficiently analyzed automatically. Available approaches mostly attempt to solve the problem by using distributed moderation systems, which are influenced by factors affecting accuracy (such as imbalance voting). Despite this, we hypothesize that analyzing and exploiting both content and context dimensions of annotations may assist the automatic moderation process. In this research, we focus on leveraging the context and content features of social web annotations for (semi-)automatic semantic moderation. This paper describes the vision of our research, proposes an approach for semi-automatic semantic moderation, introduces an ongoing effort from which we collect data that can serve as a basis for evaluating our assumption, and report on lessons learned so far." ; swrc:year "2012" ; foaf:maker . a swc:Presenter ; rdfs:label "Presenter of Potential Good Abandonment Prediction" ; swc:heldBy ; swc:isRoleAt . a foaf:Person ; rdfs:label "Wolf Siberski" ; swrc:affiliation ; foaf:based_near ; foaf:firstName "Wolf" ; foaf:lastName "Siberski" ; foaf:made ; foaf:mbox_sha1sum "3e974fd86be15908d8c3421c6077e5712a648cff" ; foaf:name "Wolf Siberski" . a foaf:Person ; rdfs:label "Guan Wang" ; swrc:affiliation ; foaf:based_near ; foaf:made ; foaf:mbox_sha1sum "2c46512223bae774e19b18261b004a194aeaa874" ; foaf:name "Guan Wang" . a foaf:Organization ; rdfs:label "National University, Galway" ; foaf:member ; foaf:name "National University, Galway" . a foaf:Person ; rdfs:label "Altigran S.

We propose a new model for creating structured summaries of information, which we call metro maps. Our proposed algorithm generates a concise structured set of documents which maximizes coverage of salient pieces of information. Most importantly, metro maps explicitly show the relations between the retrieved pieces in a way which captures story development. In this work, we formalize the characteristics of a good map and formulate it as an optimization problem. We then provide efficient methods with theoretical guarantees for generating maps. Finally, we integrate user interaction into our framework, allowing users to alter the maps to better reflect their interests.

First, we perform a comparative analysis between user-generated tags and professional annotations in terms of what aspects of videos they describe. Second, we measure how well user tags are suited for fragment retrieval and compare it with fragment search based on other sources like transcripts and professional annotations. Third, as previous research suggested that user tags predominately refer to objects and rarely describe scenes, we will study whether user tags can be successfully exploited to generate scene-level descriptions.

Even web content that is automatically generated from back-end databases is usually presented without the original structural information. In this paper, we present an automated information extraction algorithm that can extract the relevant attribute-value pairs from product descriptions across different sites. A notion, called structural-semantic entropy, is used to locate the data of interest on web pages, which measures the density of occurrence of relevant information on the DOM tree representation of web pages. Our approach is less labor-intensive and insensitive to changes in web-page format. Experimental results on a large number of real-life web page collections are encouraging and confirm the feasibility of the approach, which has been successfully applied to detect false drug advertisements on the Web due to its capacity in associating the attributes of records with their respective values." ; swrc:year "2012" ; foaf:maker . a foaf:Person ; rdfs:label "Zhijun Yin" ; swrc:affiliation ; foaf:based_near ; foaf:made ; foaf:mbox_sha1sum "4d1afae6aafbb1e5a3e7e9763d35fa3556800886" ; foaf:name "Zhijun Yin" . a event:Event , swc:TalkEvent ; rdfs:label "Paper presentation: Echoes of Power: Language Effects and Power Differences in Social Interaction" ; swc:hasLocation ; swc:hasRelatedDocument ; swc:hasRole ; swc:isSubEventOf , ; event:agent ; event:place ; icaltzd:location ; icaltzd:summary "Paper presentation: Echoes of Power: Language Effects and Power Differences in Social Interaction" . a foaf:Organization ; rdfs:label "National Taiwan University" ; foaf:member , , ; foaf:name "National Taiwan University" . a swrc:InProceedings ; rdfs:label "Efficient Multi-View Maintenance in the Social Semantic Web" ; swc:isPartOf , ; dce:creator , , ; dce:subject "Graph Databases" , "RDF" , "Social Semantic Web" , "View Maintenance" ; dce:title "Efficient Multi-View Maintenance in the Social Semantic Web" ; bibo:authorList ; swrc:abstract """The Social Semantic Web (SSW) refers to the mix of RDF data in web content, and social network data associated with those who posted that content. Applications to monitor the SSW are becoming increasingly popular. For instance, marketers want to look for semantic patterns relating to the content of tweets and Facebook posts relating to their products. Law enforcement agencies want to track behaviors involving potential criminals on the Internet by looking for certain patterns of behavior. Music companies want to track patterns of spread of illegal music. These applications allow multiple users to specify patterns of interest, and monitor them in real-time as new data gets added to the web or to a social network. In this paper, we develop the concept of SSW view servers in which all of these types of applications can be simultaneously monitored from such servers. The patterns of interest are views. We show that a given set of views can be compiled in multiple possible ways to take advantage of common substructures, and define the concept of an optimal merge. We develop a very fast MultiView algorithm that scalably and efficiently maintains multiple subgraph views. We show that our algorithm is correct, study its complexity, and experimentally demonstrate that our algorithm can scalably handle updates to hundreds of views on real-world SSW databases with up to 540M edges.""" ; swrc:year "2012" ; foaf:maker , , . a swrc:InProceedings ; rdfs:label "How to Run your Favorite Language in Web Browsers" ; swc:isPartOf , ; dce:creator , , ; dce:subject "virtual machine" , "web browser" , "language implementation" ; dce:title "How to Run your Favorite Language in Web Browsers" ; bibo:authorList ; swrc:abstract "This paper is a concise guide for developers who want to port an existing language to Web browsers, about what to do and what not to.

A dominant number of the movies are in Yoruba language spoken by over 20 million people across the globe. The number of Yoruba language movies uploaded to YouTube and their corresponding comments is growing exponentially. However, YouTube comments made by native speakers on Yoruba movies combine English language, Yoruba language, and other commonly used “pidgin” Yoruba language words. Since Yoruba is still a resource constrained language, existing sentiment or subjectivity analysis algorithms have poor performances on YouTube comments made on Yoruba language movies. This is because of the constrained language ambiguities. In this work, we present an automatic sentiment analysis algorithm for YouTube comments on Yoruba language movies. The algorithm uses SentiWordNet thesaurus and a lexicon of commonly used Yoruba language sentiment words and phrases. In terms of precision-recall, the algorithm performs more than a state-of-the-art sentiment analysis technique by up to 20%." ; swrc:year "2012" ; foaf:maker , , . a swc:Presenter ; rdfs:label "Presenter of Scalable Search Platform: Improving Pipelined Query Processing for Distributed Full-Text Retrieval" ; swc:heldBy ; swc:isRoleAt . a foaf:Person ; rdfs:label "Su-Lin Wu" ; swc:holdsRole ; foaf:firstName "Su-Lin" ; foaf:lastName "Wu" ; foaf:mbox_sha1sum "7250d8b139acd03dd5f629e7fdef921a751adb4a" ; foaf:name "Su-Lin Wu" . a foaf:Person ; rdfs:label "Ming Hua" ; swc:holdsRole ; foaf:firstName "Ming" ; foaf:lastName "Hua" ; foaf:mbox_sha1sum "f8ca677f2798c8177d9c8459d06c7e19c5a556b5" ; foaf:name "Ming Hua" . a foaf:Organization ; rdfs:label "Fraunhofer IGD" ; foaf:member ; foaf:name "Fraunhofer IGD" . rdf:_1 . a swrc:InProceedings ; rdfs:label "Exploiting Various Implicit Feedback for Collaborative Filtering" ; swc:isPartOf , ; dce:creator , , , ; dce:subject "Recommender systems" , "Implicit feedback" , "Rating function" , "User behavior" ; dce:title "Exploiting Various Implicit Feedback for Collaborative Filtering" ; bibo:authorList ; swrc:abstract "So far, many researchers have worked on recommender systems using users’ implicit feedback, since it is difficult to collect explicit item preferences in most applications.

In this paper, we show that users’ diverse implicit feedbacks can be significantly used to improve recommendation accuracy. We classify various users’ behaviors (e.g. search item, skip, add to playlist, etc.) into positive or negative feedback groups and construct more accurate pseudo- rating matrix. Our preliminary experimental result shows significant potential of our approach.

Queries occur at nodes in a network, documents are also created by nodes in the same network, and the goal is to find the document that matches the query and is closest in network distance to the node issuing the query. In this paper, we present the ``Partitioned Multi-Indexing'' scheme, which provides an approximate solution for this problem. Our scheme requires pre-processing time that is $\\tilde{O}(m)$ where $m$ is the number of links in the network\\footnote{The $\\tilde{O}(m)$ notation hides factors that are poly-logarithmic in the $m$.}. After this pre-processing, our scheme allows for social index operations (i.e., social search queries, insertion of words into a document at any node, and deletion of words), all in time $\\tilde{O}(1)$. Further, this scheme can be implemented to work on open source distributed streaming systems such as Yahoo! S4 or Twitter's Storm so that every social index operation takes $\\tilde{O}(1)$ processing time and network queries in the worst case, and just two network queries in the common case where the reverse index corresponding to the query keyword is much smaller than the memory available at any distributed compute node. Our scheme builds upon an approximate distance oracle of Das Sarma et al. \\cite{DasSarma10}. The worst-case approximation ratio of our scheme is $\\tilde{O}(1)$ for undirected networks; our simulations on the social network Twitter as well as synthetic networks show that in practice, the approximation ratio is actually close to 1 for both directed and undirected networks. We believe that this work is the first demonstration of the feasibility of social search with real-time text updates at large scales." ; swrc:month "April" ; swrc:year "2012" ; foaf:maker , . a foaf:Person ; rdfs:label "Silvio Lattanzi" ; swc:holdsRole ; foaf:firstName "Silvio" ; foaf:lastName "Lattanzi" ; foaf:mbox_sha1sum "1e50e8486cbf11f626d930ed574d0fb93160f39d" ; foaf:name "Silvio Lattanzi" . a foaf:Person ; rdfs:label "Shenghua Bao" ; swc:holdsRole ; swrc:affiliation ; foaf:based_near ; foaf:firstName "Shenghua" ; foaf:lastName "Bao" ; foaf:mbox_sha1sum "9aef05c9b133e7c180892f23fa71973fe2a79a58" ; foaf:name "Shenghua Bao" . a foaf:Person ; rdfs:label "Ke Tao" ; swrc:affiliation ; foaf:based_near ; foaf:firstName "Ke" ; foaf:lastName "Tao" ; foaf:made ; foaf:mbox_sha1sum "6b64844818c455de576a148dc3e5f9ce0aa582aa" ; foaf:name "Ke Tao" . rdf:_1 ; rdf:_2 ; rdf:_3 ; rdf:_4 . a event:Event , swc:WorkshopEvent ; rdfs:comment """

The goal of FoCUS is to trawl relevant forum content from the web with minimal overhead. Forum threads contain information content that is the target of forum crawlers. Although forums have different layouts or styles and are powered by different forum software packages, they always have similar implicit navigation paths connected by specific URL types to lead users from entry pages to thread pages. Based on this observation, we reduce the web forum crawling problem to a URL-type recognition problem and show how to learn accurate and effective regular expression patterns of implicit navigation paths from an automatically created training set using aggregated results from weak page type classifiers. Robust page type classifiers can be trained from as few as 5 annotated forums and applied to a large set of unseen forums. Our test results show that FoCUS achieved over 98% effectiveness and 97% coverage on a large set of test forums powered by over 150 different forum software packages." ; swrc:year "2012" ; foaf:maker , , . a event:Event , swc:TalkEvent ; rdfs:label "Paper presentation: Adding Wings to Red Bull Media" ; swc:hasLocation ; swc:hasRelatedDocument ; swc:hasRole ; swc:isSubEventOf , ; event:agent ; event:place ; icaltzd:location ; icaltzd:summary "Paper presentation: Adding Wings to Red Bull Media" . a foaf:Person ; rdfs:label "Marek Ciglan" ; swc:holdsRole ; swrc:affiliation ; foaf:based_near ; foaf:firstName "Marek" ; foaf:lastName "Ciglan" ; foaf:made ; foaf:mbox_sha1sum "be9034c4d072bc25bb7749e910a93ce4d4c52325" ; foaf:name "Marek Ciglan" . swc:hasPart , , , , , , , , , . a foaf:Person ; rdfs:label "Purushottam Kulkarni" ; swc:holdsRole ; swrc:affiliation ; foaf:based_near ; foaf:firstName "Purushottam" ; foaf:lastName "Kulkarni" ; foaf:mbox_sha1sum "4bfc7a335410bbc9476b69cf3a989a55b9f8cd59" ; foaf:name "Purushottam Kulkarni" . a foaf:Person ; rdfs:label "Lluís Màrquez" ; swrc:affiliation ; foaf:based_near ; foaf:firstName "Lluís" ; foaf:lastName "Màrquez" ; foaf:made ; foaf:mbox_sha1sum "0fd6996cc6351eca97c79b2d142218648041b53c" ; foaf:name "Lluís Màrquez" . a foaf:Person ; rdfs:label "Alexandre Gerber" ; swrc:affiliation ; foaf:based_near ; foaf:firstName "Alexandre" ; foaf:lastName "Gerber" ; foaf:made ; foaf:mbox_sha1sum "bdf03d67156fb0f2a33e46fa41f3cbe3a514bab3" ; foaf:name "Alexandre Gerber" . a event:Event , swc:SessionEvent ; rdfs:comment "Data Management" ; rdfs:label "EU Track S1 - Data Management" ; swc:hasLocation ; swc:isSuperEventOf , , , ; event:place ; event:time ; dce:description "Data Management" ; icaltzd:dtend "2012-04-18T15:30:00+02:00"^^ ; icaltzd:dtstart "2012-04-18T14:00:00+02:00"^^ ; icaltzd:location . a foaf:Person ; rdfs:label "Sasidhar Kasturi" ; swrc:affiliation ; foaf:based_near ; foaf:firstName "Sasidhar" ; foaf:lastName "Kasturi" ; foaf:made ; foaf:mbox_sha1sum "de8a72a782a03169a21ac7c9fc6c4f369c372d57" ; foaf:name "Sasidhar Kasturi" . a foaf:Person ; rdfs:label "Boris Kostenko" ; swrc:affiliation ; foaf:based_near ; foaf:firstName "Boris" ; foaf:lastName "Kostenko" ; foaf:made ; foaf:mbox_sha1sum "15fefbab2a812d928959e72462d00ca44108d153" ; foaf:name "Boris Kostenko" . a foaf:Person ; rdfs:label "Amanda Spink" ; swc:holdsRole ; swrc:affiliation ; foaf:based_near ; foaf:firstName "Amanda" ; foaf:lastName "Spink" ; foaf:mbox_sha1sum "6d2d74ba10d2e59106ee01b76b5e010f21f0b8b5" ; foaf:name "Amanda Spink" . a foaf:Person ; rdfs:label "Serge Abiteboul" ; swc:holdsRole , ; swrc:affiliation , ; foaf:based_near , ; foaf:firstName "Serge" ; foaf:lastName "Abiteboul" ; foaf:made ; foaf:mbox_sha1sum "31035e7af8e738a3c6b5f7747d67e306fbe5846c" ; foaf:name "Serge Abiteboul" . a swc:Presenter ; rdfs:label "Presenter of Comparative Evaluation of JavaScript Frameworks" ; swc:heldBy ; swc:isRoleAt . a foaf:Person ; rdfs:label "Georg Buscher" ; swc:holdsRole ; swrc:affiliation ; foaf:based_near ; foaf:firstName "Georg" ; foaf:lastName "Buscher" ; foaf:mbox_sha1sum "f091816565af0bf37d33c45cc9986709669c6eb4" ; foaf:name "Georg Buscher" . a foaf:Person ; rdfs:label "Gregory Grefenstette" ; swc:holdsRole , , ; swrc:affiliation , ; foaf:based_near , ; foaf:firstName "Gregory" ; foaf:lastName "Grefenstette" ; foaf:mbox_sha1sum "a138fbddc686da69b2f9921ced5ff3f1914b775f" ; foaf:name "Gregory Grefenstette" . a foaf:Person ; rdfs:label "Dmitri Perelman" ; swc:holdsRole ; swrc:affiliation ; foaf:based_near ; foaf:firstName "Dmitri" ; foaf:lastName "Perelman" ; foaf:made ; foaf:mbox_sha1sum "852d30f6b3a451ed8d9468c77d58c415e3378e27" ; foaf:name "Dmitri Perelman" . a foaf:Person ; rdfs:label "Georgia Koutrika" ; swc:holdsRole , ; swrc:affiliation ; foaf:based_near ; foaf:firstName "Georgia" ; foaf:lastName "Koutrika" ; foaf:mbox_sha1sum "6b605fe1f8d1627c35d970df93c0acaecf383388" ; foaf:name "Georgia Koutrika" . a foaf:Organization ; rdfs:label "Johannes Kepler University" ; foaf:member , ; foaf:name "Johannes Kepler University" . a swrc:InProceedings ; rdfs:label "Hierarchical Composable Optimization of Web Pages" ; swc:isPartOf , ; dce:creator , , , , , , , , ; dce:subject "Web page modeling" , "Web page creation and optimization" , "Algorithmic Page Layout" ; dce:title "Hierarchical Composable Optimization of Web Pages" ; bibo:authorList ; swrc:abstract """The process of creating modern Web media experiences is challenged by the need to adapt the content and presentation choices to dynamic real-time fluctuations of user interest across multiple audiences. We introduce FAME -- a Framework for Agile Media Experiences -- which addresses this scalability problem. FAME allows media creators to define abstract page models that are subsequently transformed into real experiences through algorithmic experimentation. FAME's page models are hierarchically composed of simple building blocks, mirroring the structure of most Web pages. They are resolved into concrete page instances by pluggable algorithms which optimize the pages for specific business goals. Our framework allows retrieving dynamic content from multiple sources, defining the experimentation's degrees of freedom, and constraining the algorithmic choices. It offers an effective separation of concerns in the media creation process, enabling multiple stakeholders with profoundly different skills to apply their crafts and perform their duties independently, composing and reusing each other's work in modular ways.""" ; swrc:year "2012" ; foaf:maker , , , , , , , , . a foaf:Person ; rdfs:label "Edleno Silva De Moura" ; swc:holdsRole ; swrc:affiliation ; foaf:based_near ; foaf:firstName "Edleno" ; foaf:lastName "Silva De Moura" ; foaf:mbox_sha1sum "ece0f11a9ec6a0f797712b901e781415c1618613" ; foaf:name "Edleno Silva De Moura" . a foaf:Person ; rdfs:label "Dana Dannells" ; swc:holdsRole ; swrc:affiliation ; foaf:based_near ; foaf:firstName "Dana" ; foaf:lastName "Dannells" ; foaf:made ; foaf:mbox_sha1sum "8d86ff7fcef36b2a31aad9d06c14d5a4c1c05811" ; foaf:name "Dana Dannells" . a foaf:Person ; rdfs:label "Tanveer Faruquie" ; swrc:affiliation ; foaf:based_near ; foaf:firstName "Tanveer" ; foaf:lastName "Faruquie" ; foaf:made ; foaf:mbox_sha1sum "e0623c599a0703e097b1d55f0025dfc3243a4208" ; foaf:name "Tanveer Faruquie" . a foaf:Organization ; rdfs:label "The University of Tokyo, National Institute of Informatics" ; foaf:member ; foaf:name "The University of Tokyo, National Institute of Informatics" . a foaf:Person ; rdfs:label "Ying Li" ; swc:holdsRole , ; swrc:affiliation ; foaf:based_near , ; foaf:firstName "Ying" ; foaf:lastName "Li" ; foaf:mbox_sha1sum "fd08393b7e30688052226ec7a0fa4b4919a7d1d8" ; foaf:name "Ying Li" . a foaf:Organization ; rdfs:label "FON - School of Business Administration, University of Belgrade" ; foaf:member ; foaf:name "FON - School of Business Administration, University of Belgrade" . a foaf:Person ; rdfs:label "Vitor Carvalho" ; swrc:affiliation ; foaf:based_near ; foaf:made ; foaf:mbox_sha1sum "b83001bee29451c99c8c838ca756fc0f634b531d" ; foaf:name "Vitor Carvalho" . a event:Event , swc:SessionEvent ; rdfs:comment " Mobile / Social Computing" ; rdfs:label "EU track S4 - Mobile / Social Computing" ; swc:hasLocation ; swc:isSuperEventOf , , , , ; event:place ; event:time ; dce:description " Mobile / Social Computing" ; icaltzd:dtend "2012-04-19T17:30:00+02:00"^^ ; icaltzd:dtstart "2012-04-19T16:00:00+02:00"^^ ; icaltzd:location . a swc:Presenter ; rdfs:label "Presenter of DIADEM: Domain-centric, Intelligent, Automated Data Extraction Methodology" ; swc:heldBy ; swc:isRoleAt . a foaf:Person ; rdfs:label "Kevin Lang" ; swc:holdsRole ; swrc:affiliation ; foaf:based_near ; foaf:firstName "Kevin" ; foaf:lastName "Lang" ; foaf:made ; foaf:mbox_sha1sum "b620319593de6aa1c4a599899601ed52a6c24e7b" ; foaf:name "Kevin Lang" . a foaf:Person ; rdfs:label "Wolfgang Nejdl" ; swc:holdsRole , ; swrc:affiliation , ; foaf:based_near , ; foaf:firstName "Wolfgang" ; foaf:lastName "Nejdl" ; foaf:made , , ; foaf:mbox_sha1sum "8f4db0c244d721b7e92ce184bd4317b94bd2f494" ; foaf:name "Wolfgang Nejdl" . a foaf:Person ; rdfs:label "Leonardo Querzoni" ; swc:holdsRole ; swrc:affiliation ; foaf:based_near ; foaf:firstName "Leonardo" ; foaf:lastName "Querzoni" ; foaf:mbox_sha1sum "378da451676a5743d141ef8becd6e0911f244979" ; foaf:name "Leonardo Querzoni" . rdf:_1 ; rdf:_2 ; rdf:_3 . a foaf:Person ; rdfs:label "Vincent Hardy" ; swrc:affiliation ; foaf:based_near ; foaf:firstName "Vincent" ; foaf:lastName "Hardy" ; foaf:made ; foaf:mbox_sha1sum "074781db70d9f181eff7361accfe30629447f72a" ; foaf:name "Vincent Hardy" . a foaf:Organization ; rdfs:label "Emory University" ; foaf:member , ; foaf:name "Emory University" . a foaf:Person ; rdfs:label "Mohamed Aly" ; swc:holdsRole ; swrc:affiliation ; foaf:based_near ; foaf:firstName "Mohamed" ; foaf:lastName "Aly" ; foaf:made ; foaf:mbox_sha1sum "17d4a497c44095abfac667877e77d5c469edb965" ; foaf:name "Mohamed Aly" . a foaf:Organization ; rdfs:label "Université Paris-Sud 11 & Inria Saclay" ; foaf:member , ; foaf:name "Université Paris-Sud 11 & Inria Saclay" . a foaf:Organization ; rdfs:label "eBay research labs" , "eBay Research Labs" ; foaf:member , , ; foaf:name "eBay research labs" , "eBay Research Labs" . a foaf:Person ; rdfs:label "Christos Doulkeridis" ; swc:holdsRole ; swrc:affiliation ; foaf:based_near ; foaf:firstName "Christos" ; foaf:lastName "Doulkeridis" ; foaf:mbox_sha1sum "41915e4bdfd6c387cf637c281ffb462d0b678bf4" ; foaf:name "Christos Doulkeridis" . a swrc:InProceedings ; rdfs:label "Extracting Client-side Web Application code" ; swc:isPartOf ; dce:creator , , ; dce:subject "Web applications" , "Reuse" , "Code Extraction" , "Slicing" ; dce:title "Extracting Client-side Web Application code" ; bibo:authorList ; swrc:abstract "The web application domain is one of the fastest growing and most wide-spread application domains today. By utilizing fast, modern web browsers and advanced scripting techniques, web developers are developing highly interactive applications that can, in terms of user-experience and responsiveness, compete with standard desktop applications. A web application is composed of two equally important parts: the server-side and the client-side. The client-side acts as an user-interface to the application, and can be viewed as a collection of behaviors. Similar behaviors are often used in a large number of applications, and facilitating their reuse oers considerable benets. However, due to client-side specics (e.g. multi-language implementation, extreme dynamicity), identifying and extracting code responsible for a certain behavior is dicult. In this paper we present a method for extracting client-side web application code implementing a certain behavior. We show how by analyzing the execution of a usage scenario, code responsible for a certain behavior can be identied, how dependencies between dierent parts of the application can be tracked, and how in the end only the code responsible for a certain behavior can be extracted. Our evaluation shows that the method is capable of extracting stand-alone behaviors, while achieving considerable savings in terms of code size and application performance." ; swrc:month "April" ; swrc:year "2012" ; foaf:maker , , . a event:Event , swc:SessionEvent ; rdfs:comment "Digital Infrastructure and Archives" ; rdfs:label "EU track S5 - Digital Infrastructure and Archives" ; swc:hasLocation ; swc:isSuperEventOf , , , ; event:place ; event:time ; dce:description "Digital Infrastructure and Archives" ; icaltzd:dtend "2012-04-20T12:30:00+02:00"^^ ; icaltzd:dtstart "2012-04-20T11:00:00+02:00"^^ ; icaltzd:location . a swrc:InProceedings ; rdfs:label "Echoes of power: How power differences between people are revealed by linguistic style coordination" ; swc:isPartOf ; dce:creator , , , ; dce:subject "coordination" , "power" , "social status" , "accommodation" , "relations" , "language" , "linguistic convergence" , "dependence" , "linguistic style" , "online communities" ; dce:title "Echoes of power: How power differences between people are revealed by linguistic style coordination" ; bibo:authorList ; swrc:abstract "Understanding social interaction within groups is key to analyzing online communities. Most current work focuses on structural properties: who talks to whom, and how such interactions form larger network structures. The interactions themselves, however, generally take place in the form of natural language --- either spoken or written --- and one could reasonably suppose that signals manifested in language might also provide information about roles, status, and other aspects of the group's dynamics. To date, however, finding such domain-independent language-based signals has been a challenge. Here, we show that in group discussions power differentials between participants are subtly revealed by how much one individual immediately echoes the linguistic style of the person they are responding to. Starting from this observation, we propose an analysis framework based on linguistic coordination that can be used to shed light on power relationships and that works consistently across multiple types of power --- including a more ''static'' form of power based on status differences, and a more ''situational'' form of power in which one individual experiences a type of dependence on another. Using this framework, we study how conversational behavior can reveal power relationships in two very different settings: discussions among Wikipedians and arguments before the U.S. Supreme Court." ; swrc:month "April" ; swrc:year "2012" ; foaf:maker , , , . a foaf:Person ; rdfs:label "Adi Littman" ; swrc:affiliation ; foaf:based_near ; foaf:made ; foaf:mbox_sha1sum "ffb2d84b4445631d30b375888836019ed4c44fc5" ; foaf:name "Adi Littman" . a foaf:Organization ; rdfs:label "University of Ghent - Multimedia Lab" ; foaf:member ; foaf:name "University of Ghent - Multimedia Lab" . a foaf:Organization ; rdfs:label "Heidelberg University" ; foaf:member , , ; foaf:name "Heidelberg University" . a event:Event , swc:SessionEvent ; rdfs:comment "Language Technology / Mobile" ; rdfs:label "EU track S3 - Language Technology / Mobile" ; swc:hasLocation ; swc:isSuperEventOf , , ; event:place ; event:time ; dce:description "Language Technology / Mobile" ; icaltzd:dtend "2012-04-19T15:30:00+02:00"^^ ; icaltzd:dtstart "2012-04-19T14:00:00+02:00"^^ ; icaltzd:location . a foaf:Person ; rdfs:label "Dirk Balfanz" ; swc:holdsRole ; swrc:affiliation ; foaf:based_near ; foaf:firstName "Dirk" ; foaf:lastName "Balfanz" ; foaf:mbox_sha1sum "5c86b157c5bd9e81eb6e6d4c1c96381f05b5656b" ; foaf:name "Dirk Balfanz" . a foaf:Organization ; rdfs:label "University of Milan" ; foaf:member ; foaf:name "University of Milan" . a foaf:Person ; rdfs:label "Judit Bar-Ilan" ; swc:holdsRole ; swrc:affiliation ; foaf:based_near ; foaf:firstName "Judit" ; foaf:lastName "Bar-Ilan" ; foaf:mbox_sha1sum "471f93284c1fb8ea9d4ada4d26cbf6c09bbfcebf" ; foaf:name "Judit Bar-Ilan" . a foaf:Person ; rdfs:label "Gal Oestreicher- Singer" ; swc:holdsRole ; swrc:affiliation ; foaf:based_near ; foaf:firstName "Gal" ; foaf:lastName "Oestreicher- Singer" ; foaf:mbox_sha1sum "dd09fc198ed903623fa98207c48f096537aa913c" ; foaf:name "Gal Oestreicher- Singer" . a foaf:Organization ; rdfs:label "I3S/University of Nice" ; foaf:member ; foaf:name "I3S/University of Nice" . a foaf:Person ; rdfs:label "Tao Cheng" ; swrc:affiliation ; foaf:based_near ; foaf:firstName "Tao" ; foaf:lastName "Cheng" ; foaf:made ; foaf:mbox_sha1sum "a423aa5a38ab7b26cf9b71afdcf2d1f97f7ae467" ; foaf:name "Tao Cheng" . a event:Event , swc:SessionEvent ; rdfs:comment "Search" ; rdfs:label "EU track S2 - Search" ; swc:hasLocation ; swc:isSuperEventOf , , , ; event:place ; event:time ; dce:description "Search" ; icaltzd:dtend "2012-04-18T17:30:00+02:00"^^ ; icaltzd:dtstart "2012-04-18T16:00:00+02:00"^^ ; icaltzd:location . a foaf:Person ; rdfs:label "Yanan Xie" ; swrc:affiliation ; foaf:based_near ; foaf:firstName "Yanan" ; foaf:lastName "Xie" ; foaf:made ; foaf:mbox_sha1sum "e6b5ed9d8219d1e6fcc514ac1cc90249188ec488" ; foaf:name "Yanan Xie" . a swc:Presenter ; rdfs:label "Presenter of Domain Adaptive Answer Extraction for Discussion Boards" ; swc:isRoleAt . a swc:Presenter ; rdfs:label "Presenter of Economics of BitTorrent Communities" ; swc:heldBy ; swc:isRoleAt . a swrc:InProceedings ; rdfs:label "Learning Causality for News Events Prediction" ; swc:isPartOf ; dce:creator , , ; dce:subject "Causality Learning from the Web" , "News Event Prediction" , "Mining Causality from the Web" ; dce:title "Learning Causality for News Events Prediction" ; bibo:authorList ; swrc:abstract "We present a new methodology for modeling and predicting future news events using machine learning and data mining techniques.

We use a number of standard statistics, which measure the security of password distributions, to see if modelling the data using Zipf's Law or a uniform distribution is effective. We then consider how much the the password distributions from each site have in common, using password guessing/cracking as a metric. This shows that these distributions have enough high-frequency passwords in common to prove effective for cracking passwords.

It is baptized Complex network cluster detection (or, shortly, CONCLUDE). The strategy relies on three steps: i) ranking edges centrality by using a random walker; ii) calculating the proximity (the inverse of the distance) between each pair of connected nodes; ii) partitioning the network into communities so to optimize the network modularity. The algorithm is computationally efficient since its cost is near linear. The adoption of our community detection method has been proved worthy in different contexts, such as online social networks and biological networks. The devised algorithm, in fact, represents a powerful technique to obtain a meaningful clustering of both weighted and unweighted networks, and its utilization for directed networks is straightforward.""" ; swrc:year "2012" ; foaf:maker . a foaf:Person ; rdfs:label "Vanessa Murdock" ; swc:holdsRole ; swrc:affiliation , ; foaf:based_near , ; foaf:firstName "Vanessa" ; foaf:lastName "Murdock" ; foaf:made ; foaf:mbox_sha1sum "944bc9ef65a90700878cfeaa1d4b19f30e6abdd9" ; foaf:name "Vanessa Murdock" . a swrc:InProceedings ; rdfs:label "Sentiment Classification via Integrating Multiple Feature Presentations" ; swc:isPartOf , ; dce:creator , , , ; dce:subject "base classifiers" , "multiple feature presentations" , "integrating" , "sentiment classification" ; dce:title "Sentiment Classification via Integrating Multiple Feature Presentations" ; bibo:authorList ; swrc:abstract "In general, the documents are converted into vectors accordingto predefined features together with weighting mechanism.But each feature presentation has its character and it isdifficult to perform very well for all domains.

They enable us to access the deep content of web sites. Automatic form understanding unlocks this content for applications ranging from crawlers to meta-search engines and is essential for improving usability and accessibility of the web. Form understanding has received surprisingly little attention other than as component in specific applications such as crawlers. No comprehensive approach to form understanding exists and previous works disagree even in the definition of the problem. In this paper, we present OPAL, the first comprehensive approach to form understanding. We identify form labeling and form interpretation as the two main tasks involved in form understanding. On both problems OPAL pushes the state of the art: For form labeling, it combines signals from the text, structure, and visual rendering of a web page, yielding robust characterisations of common design patterns. In extensive experiments on the ICQ and TEL-8 benchmarks and a set of 200 modern web forms OPAL outperforms previous approaches by a significant margin. For form interpretation, we introduce a template language to describe frequent form patterns. These two parts of OPAL combined yield form understanding with near perfect accuracy (> 98%)." ; swrc:month "April" ; swrc:year "2012" ; foaf:maker , , , , , . a event:Event , swc:PanelEvent ; rdfs:comment "#OPENDATA-WEBSCI" ; rdfs:label "Web Science Panel 2 - Open Data: technological and societal opportunities and challenges" ; swc:hasLocation ; event:place ; event:time ; dce:description "#OPENDATA-WEBSCI" ; icaltzd:dtend "2012-04-20T15:30:00+02:00"^^ ; icaltzd:dtstart "2012-04-20T14:00:00+02:00"^^ ; icaltzd:location . a foaf:Person ; rdfs:label "Enrique Alfonseca" ; swc:holdsRole ; swrc:affiliation ; foaf:based_near ; foaf:firstName "Enrique" ; foaf:lastName "Alfonseca" ; foaf:mbox_sha1sum "e774e2f82c3d6b02be938b491831b51287ac4684" ; foaf:name "Enrique Alfonseca" . a foaf:Person ; rdfs:label "Mathieu D'Aquin" , "Mathieu D’aquin" ; swc:holdsRole ; swrc:affiliation ; foaf:based_near ; foaf:firstName "Mathieu" ; foaf:lastName "D'Aquin" ; foaf:made ; foaf:mbox_sha1sum "e61cc68181adeb9fbbddc539a6fa01dd24b299c8" ; foaf:name "Mathieu D'Aquin" , "Mathieu D’aquin" . a foaf:Person ; rdfs:label "Ramona Enache" ; swrc:affiliation ; foaf:based_near ; foaf:firstName "Ramona" ; foaf:lastName "Enache" ; foaf:made ; foaf:mbox_sha1sum "972057e7e18fb5df18a46784fa244047eee83e17" ; foaf:name "Ramona Enache" . a event:Event , swc:TalkEvent ; rdfs:label "Paper presentation: A Revenue Sharing Mechanism for Federated Search and Advertising" ; swc:hasLocation ; swc:hasRelatedDocument ; swc:hasRole ; swc:isSubEventOf , ; event:agent ; event:place ; icaltzd:location ; icaltzd:summary "Paper presentation: A Revenue Sharing Mechanism for Federated Search and Advertising" . a event:Event , swc:TalkEvent ; rdfs:label "Paper presentation: SnoopyTagging: Recommending Contextualized Tags to Increase the Quality and Quantity of Meta-Information" ; swc:hasLocation ; swc:hasRelatedDocument ; swc:hasRole ; swc:isSubEventOf , ; event:agent ; event:place ; icaltzd:location ; icaltzd:summary "Paper presentation: SnoopyTagging: Recommending Contextualized Tags to Increase the Quality and Quantity of Meta-Information" . a foaf:Organization ; rdfs:label "Universit degli STudi di Milano Bicocca" ; foaf:member ; foaf:name "Universit degli STudi di Milano Bicocca" . a swc:Presenter ; rdfs:label "Presenter of Counting Beyond a Yottabyte, or how SPARQL 1.1 Property Paths will Prevent Adoption of the Standard" ; swc:heldBy ; swc:isRoleAt . a swc:Presenter ; rdfs:label "Presenter of Semantic Evaluation At Large Scale (SEALS)" ; swc:isRoleAt . a foaf:Person ; rdfs:label "Sergei Vassilvitskii" ; swc:holdsRole ; swrc:affiliation , ; foaf:based_near , ; foaf:firstName "Sergei" ; foaf:lastName "Vassilvitskii" ; foaf:made ; foaf:mbox_sha1sum "b3b804269a13b5653e2718d9033ef5093d9055e6" , "97dd6ba9cbeb9e5fc1f22d98d32bab1b8f6fbefc" ; foaf:name "Sergei Vassilvitskii" . rdf:_1 ; rdf:_2 ; rdf:_3 ; rdf:_4 . a swrc:InProceedings ; rdfs:label "Modeling the Flow and Change of Information on the Web" ; swc:isPartOf , ; dce:creator ; dce:subject "Web mining" , "stochastic modeling" , "blogs" , "news media" ; dce:title "Modeling the Flow and Change of Information on the Web" ; bibo:authorList ; swrc:abstract "The proposed PhD work approaches the problem of information flow and change on the Web.

The system, called Session Juggler, requires no server-side changes and no special software on the terminal beyond a modern web browser. This important property makes adoption much easier than with previous proposals. With Session Juggler users never enter their long term credential on the untrusted terminal. Instead, users log in to a web site using a smartphone app and then transfer the entire session, including cookies and all other session state, to the untrusted terminal. We show that Session Juggler works on all the Alexa top 100 sites (except three because the Android browser is not able to render them). We also show that Session Juggler works flawlessly with Facebook connect. Beyond login, Session Juggler also provides a secure logout mechanism where the trusted phone is used to kill the session. To validate the session juggling concept we conducted a number of web site surveys that are of independent interest. First, we survey how web sites bind a session token to a specific device and show that most use fairly basic techniques that are easily defeated. Second, we survey how web sites handle logout and show that many popular sites surprisingly do not properly handle logout requests." ; swrc:month "April" ; swrc:year "2012" ; foaf:maker , , , . a foaf:Person ; rdfs:label "Markus Schedl" ; swrc:affiliation ; foaf:based_near ; foaf:made ; foaf:mbox_sha1sum "5d1306d14d5f5e6af24bf1387c4108511252cda4" ; foaf:name "Markus Schedl" . a swc:Presenter ; rdfs:label "Presenter of Data Extraction from Web Pages Based on Structural-Semantic Entropy" ; swc:heldBy ; swc:isRoleAt . a event:Event , swc:TalkEvent ; rdfs:label "Paper presentation: Human Wayfinding in Information Networks" ; swc:hasLocation ; swc:hasRelatedDocument ; swc:hasRole ; swc:isSubEventOf , ; event:agent ; event:place ; icaltzd:location ; icaltzd:summary "Paper presentation: Human Wayfinding in Information Networks" . a event:Event , swc:PanelEvent ; rdfs:comment "

Yet, similar to what happened with analogous promises in web service composition and business process management, research has mostly focused on technology and, as a consequence, has failed its objective. Plain technology (e.g., SOAP/WSDL web services) or simple modeling languages (e.g., Yahoo! Pipes) don't convey enough meaning to non-programmers.We propose a domain-specific approach to mashups that \"speaks the language of the user\", i.e., that is aware of the terminology, concepts, rules, and conventions (the domain) the user is comfortable with. We show what developing a domain-specific mashup tool means, which role the mashup meta-model and the domain model play and how these can be merged into a domain-specific mashup meta-model.We apply the approach implementing a mashup tool for the research evaluation domain. Our user study confirms that domain-specific mashup tools indeed lower the entry barrier to mashup development." ; swrc:year "2012" ; foaf:maker , , , , , . a swrc:InProceedings ; rdfs:label "Using Variational Inference and MapReduce to Scale Topic Modeling" ; swc:isPartOf ; dce:creator , , ; dce:subject "variational inference" , "online inference" , "topic modeling" , "multilingual" , "lda" , "scale" , "mapreduce" ; dce:title "Using Variational Inference and MapReduce to Scale Topic Modeling" ; bibo:authorList ; swrc:abstract "Latent Dirichlet Allocation (LDA) is a popular topic modeling technique for exploring document collections.

In contrast to other techniques to scale inference for LDA, which use Gibbs sampling, we use variational inference. Our solution efficiently distributes computation and is relatively simple to implement.

We provide three main results: 1) online consumption is more concentrated than off-line audience, contradicting the hypothesis of a long tail effect of catch up TV; 2) the temporality of replay TV consumption on the web is very close to the live broadcasting of the programs, thus softening rather than breaking the synchrony of traditional TV; 3) detailed data on online consumption of news reveals two patterns of consumption (“alternative TV ritual” vs. “à la carte”)." ; swrc:year "2012" ; foaf:maker , . a event:Event , swc:TalkEvent ; rdfs:label "Paper presentation: T@gz : Intuitive and Effortless Categorization and Sharing of Email Conversations" ; swc:hasLocation ; swc:hasRelatedDocument ; swc:hasRole ; swc:isSubEventOf , ; event:agent ; event:place ; icaltzd:location ; icaltzd:summary "Paper presentation: T@gz : Intuitive and Effortless Categorization and Sharing of Email Conversations" . a event:Event , swc:TalkEvent ; rdfs:label "Paper presentation: Structured Query Suggestion for Specialization and Parallel Movement: Effect on Search Behaviors" ; swc:hasLocation ; swc:hasRelatedDocument ; swc:hasRole ; swc:isSubEventOf , ; event:agent ; event:place ; icaltzd:location ; icaltzd:summary "Paper presentation: Structured Query Suggestion for Specialization and Parallel Movement: Effect on Search Behaviors" . a foaf:Organization ; rdfs:label "Microsoft Research" ; foaf:member , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , ; foaf:name "Microsoft Research" . a foaf:Person ; rdfs:label "Yushi Jing" ; swrc:affiliation ; foaf:based_near ; foaf:made ; foaf:mbox_sha1sum "1cbacae610c11d0cac0eb2c070b625e1d6156343" ; foaf:name "Yushi Jing" . a foaf:Person ; rdfs:label "Haofen Wang" ; swc:holdsRole ; swrc:affiliation ; foaf:based_near ; foaf:firstName "Haofen" ; foaf:lastName "Wang" ; foaf:mbox_sha1sum "0233b9fd11287c2f4beecdd5a3002eb5cae9f080" ; foaf:name "Haofen Wang" . rdf:_1 ; rdf:_2 ; rdf:_3 . a foaf:Person ; rdfs:label "Martin Hepp" ; swc:holdsRole ; swrc:affiliation ; foaf:based_near ; foaf:firstName "Martin" ; foaf:lastName "Hepp" ; foaf:mbox_sha1sum "49e06491d1c02eead2d362e2300fa56d24ed5213" ; foaf:name "Martin Hepp" . a foaf:Organization ; rdfs:label "GIDIS_Web, Engineering School, UNLPam" ; foaf:member ; foaf:name "GIDIS_Web, Engineering School, UNLPam" . tl:end "2012-04-19T10:30:00+02:00"^^ ; tl:start "2012-04-19T10:15:00+02:00"^^ . rdf:_1 . a swc:Presenter ; rdfs:label "Presenter of A Framework to Represent and Mine Knowledge Evolution from Wikipedia Revisions" ; swc:heldBy ; swc:isRoleAt . a foaf:Person ; rdfs:label "Matthieu Latapy" ; swc:holdsRole ; swrc:affiliation ; foaf:based_near ; foaf:firstName "Matthieu" ; foaf:lastName "Latapy" ; foaf:mbox_sha1sum "9aa4fe1f18c3dcff7fffdf16edef1a572ec9d7fe" ; foaf:name "Matthieu Latapy" . a foaf:Organization ; rdfs:label "Nara Institute of Science and Technology" ; foaf:member ; foaf:name "Nara Institute of Science and Technology" . a foaf:Person ; rdfs:label "David Konopnicki" ; swc:holdsRole ; swrc:affiliation ; foaf:based_near ; foaf:firstName "David" ; foaf:lastName "Konopnicki" ; foaf:mbox_sha1sum "fe59ae676106a0404883102b5e00e1a55786ca10" ; foaf:name "David Konopnicki" . a swc:Presenter ; rdfs:label "Speaker at Leveraging User-Generated Content" ; swc:heldBy ; swc:isRoleAt . rdf:_1 ; rdf:_2 . a foaf:Person ; rdfs:label "Jiawei Han" ; swc:holdsRole ; swrc:affiliation , ; foaf:based_near , ; foaf:firstName "Jiawei" ; foaf:lastName "Han" ; foaf:made ; foaf:mbox_sha1sum "956716bc0ecaaa72fa3c793443aed142095d153d" ; foaf:name "Jiawei Han" . a foaf:Organization ; rdfs:label "University of California at Santa Barbara" ; foaf:member , ; foaf:name "University of California at Santa Barbara" . a event:Event , swc:TalkEvent ; rdfs:label "Paper presentation: OPAL: Automated Form Understanding for the Deep Web" ; swc:hasLocation ; swc:hasRelatedDocument ; swc:hasRole ; swc:isSubEventOf , ; event:agent ; event:place ; icaltzd:location ; icaltzd:summary "Paper presentation: OPAL: Automated Form Understanding for the Deep Web" . rdf:_1 ; rdf:_2 ; rdf:_3 . a foaf:Organization ; rdfs:label "ICCS/NTUA" ; foaf:member ; foaf:name "ICCS/NTUA" . a foaf:Person ; rdfs:label "Jalal Mahmud" ; swc:holdsRole ; swrc:affiliation ; foaf:based_near ; foaf:firstName "Jalal" ; foaf:lastName "Mahmud" ; foaf:mbox_sha1sum "0ee8348ed85e84881b1ef9fbe1085baa07807395" ; foaf:name "Jalal Mahmud" . tl:end "2012-04-19T10:15:00+02:00"^^ ; tl:start "2012-04-19T10:00:00+02:00"^^ . a swrc:InProceedings ; rdfs:label "A Framework to Represent and Mine Knowledge Evolution from Wikipedia Revisions" ; swc:isPartOf , ; dce:creator , , , , , , ; dce:subject "Expired Data Detection" , "Knowledge Evolution Extraction" , "Wikipedia Revision" ; dce:title "A Framework to Represent and Mine Knowledge Evolution from Wikipedia Revisions" ; bibo:authorList ; swrc:abstract "State-of-the-art knowledge representation in semantic web employs a triple format (subject-relation-object). The limitation is that it can only represent static information, but cannot easily encode revisions of semantic web and knowledge evolution. In reality, knowledge does not stay still but evolves over time. In this paper, we first introduce the concept of \"quintuple representation\" by adding two new fields, \"state\" and \"time\", where \"state\" has two values, either in or out, to denote that the referred knowledge takes effective or becomes expired at the given \"time\". We then discuss a two-step statistical framework to mine knowledge evolution into the proposed quintuple representation. Utilizing extracted quintuple properly, it can not only reveal knowledge changing history but also detect expired information. We evaluate the proposed framework on Wikipedia revisions, as well as, common web pages currently not in semantic web format." ; swrc:year "2012" ; foaf:maker , , , , , , . a foaf:Person ; rdfs:label "Cailin Cushing" ; swrc:affiliation ; foaf:based_near ; foaf:firstName "Cailin" ; foaf:lastName "Cushing" ; foaf:made ; foaf:mbox_sha1sum "c2fd5f51a211672fc9ba6d952ed0b8bd283518a2" ; foaf:name "Cailin Cushing" . a foaf:Person ; rdfs:label "Joseph Hellerstein" ; swc:holdsRole ; swrc:affiliation ; foaf:based_near ; foaf:firstName "Joseph" ; foaf:lastName "Hellerstein" ; foaf:mbox_sha1sum "be07bd42281e235c7247d28901744c396af0c4a4" ; foaf:name "Joseph Hellerstein" . a event:Event , swc:TalkEvent ; rdfs:label "Paper presentation: Information Transfer in Social Media" ; swc:hasLocation ; swc:hasRelatedDocument ; swc:hasRole ; swc:isSubEventOf , ; event:agent ; event:place ; icaltzd:location ; icaltzd:summary "Paper presentation: Information Transfer in Social Media" . a foaf:Person ; rdfs:label "Li Zhang" ; swrc:affiliation ; foaf:based_near ; foaf:made ; foaf:mbox_sha1sum "d8b61170692fee00bfff15883fd98d181dac9008" ; foaf:name "Li Zhang" . a event:Event , swc:TalkEvent ; rdfs:label "Paper presentation: Understanding Human Movement Semantics: A Point of Interest Based Approach" ; swc:hasLocation ; swc:hasRelatedDocument ; swc:hasRole ; swc:isSubEventOf , ; event:agent ; event:place ; icaltzd:location ; icaltzd:summary "Paper presentation: Understanding Human Movement Semantics: A Point of Interest Based Approach" . a foaf:Organization ; rdfs:label "Network Center, Tsinghua University" ; foaf:member ; foaf:name "Network Center, Tsinghua University" . a foaf:Person ; rdfs:label "Xin Jin" ; swrc:affiliation ; foaf:based_near ; foaf:made ; foaf:mbox_sha1sum "86f8b94f941559d059f4f07a78cd539cb6dd9325" ; foaf:name "Xin Jin" . a foaf:Person ; rdfs:label "Kevin Chang" ; swc:holdsRole ; swrc:affiliation ; foaf:based_near ; foaf:firstName "Kevin" ; foaf:lastName "Chang" ; foaf:mbox_sha1sum "e425443406bede3df21cf296377210b76dc5ccf4" ; foaf:name "Kevin Chang" . a event:Event , swc:TalkEvent ; rdfs:label "Paper presentation: Treehugger or Petrolhead?" ; swc:hasLocation ; swc:hasRelatedDocument ; swc:hasRole ; swc:isSubEventOf , ; event:agent ; event:place ; icaltzd:location ; icaltzd:summary "Paper presentation: Treehugger or Petrolhead?" . a swrc:InProceedings ; rdfs:label "Querying Socio-spatial Networks on the World-Wide Web" ; swc:isPartOf , ; dce:creator , , ; dce:subject "Query Language" , "Social Networks" , "Spatial Networks" , "GPS Trajectories" ; dce:title "Querying Socio-spatial Networks on the World-Wide Web" ; bibo:authorList ; swrc:abstract """Many devices, such as cellular phones and GPS-based navigation systems, allow users to record their location history.

However, due to the reason of profit or fame, people try to game the system by opinion spamming (e.g., writing fake reviews) to promote or demote some target products. For reviews to reflect genuine user experiences and opinions, such spam reviews should be detected. Prior works on opinion spam focused on detecting fake reviews and individual spammers. However, a spammer group (a group of reviewers who work collaboratively to write fake reviews) is even more damaging and can take total control of the sentiment on the target product due to its size. This paper studies spam detection in the collaborative setting, i.e., to discover review spammer groups. The proposed method first uses a frequent itemset mining method to find a set of candidate groups. It then uses several behavioral models derived from the collusion phenomenon among spammers and relation models based on inter-relationships among products, groups, and individual reviewers to detect spammer groups. Additionally, we also built a labeled group spam dataset. To the best of our knowledge, this is the first labeled dataset on group opinion spam. Experimental results show that the proposed method is highly effective and it outperforms multiple strong baselines including both the state-of-the-art learning to rank and supervised classification algorithms." ; swrc:month "April" ; swrc:year "2012" ; foaf:maker , . a foaf:Person ; rdfs:label "Jatinder Singh" ; swrc:affiliation ; foaf:based_near ; foaf:firstName "Jatinder" ; foaf:lastName "Singh" ; foaf:made ; foaf:mbox_sha1sum "cd6852a674903b3a8b74dfa6c311e73a4c62c730" ; foaf:name "Jatinder Singh" . a foaf:Organization ; rdfs:label "Stanford" , "Stanford University" ; foaf:member , , , , , , , , , , , , , , , , , , , , , , , , , ; foaf:name "Stanford" , "Stanford University" . a swrc:InProceedings ; rdfs:label "Model News Relatedness through User Comments" ; swc:isPartOf , ; dce:creator , , , ; dce:subject "User comments" , "News Relatedness" , "Community rating" ; dce:title "Model News Relatedness through User Comments" ; bibo:authorList ; swrc:abstract "Recommending related news articles aims to engage with users afterthey read current ones and can improve user retention for newsproviders.

Upon acceptance of a recommendation, the purposeful design of the respective pattern types allows us to automatically weave the chosen pattern into a partial mashup model, in practice performing a set of modeling actions on behalf of the developer.The experimental evaluation of our prototype implementation demonstrates that it is indeed possible to harvest meaningful, reusable knowledge from existing mashups, and that even complex recommendations can be efficiently queried and weaved also inside the client browser." ; swrc:year "2012" ; foaf:maker , , , , . a foaf:Person ; rdfs:label "Jean-Samuel Beuscart" ; swrc:affiliation ; foaf:based_near ; foaf:made ; foaf:mbox_sha1sum "f931c838307d528efe4f436008c6e10c09f8904c" ; foaf:name "Jean-Samuel Beuscart" . a foaf:Organization ; rdfs:label "Sapienza University Rome" ; foaf:member ; foaf:name "Sapienza University Rome" . a foaf:Person ; rdfs:label "Ismail Sengor Altingovde" ; swrc:affiliation ; foaf:based_near ; foaf:firstName "Ismail" ; foaf:lastName "Altingovde" ; foaf:made ; foaf:mbox_sha1sum "fc1328e01adf175018035bcffee6e5819cfd2e74" ; foaf:name "Ismail Sengor Altingovde" . a foaf:Person ; rdfs:label "Jeon-Hyung Kang" ; swc:holdsRole ; swrc:affiliation ; foaf:based_near ; foaf:firstName "Jeon-Hyung" ; foaf:lastName "Kang" ; foaf:made ; foaf:mbox_sha1sum "2882bbf2ceed037bc55ababed06767da95540b6b" ; foaf:name "Jeon-Hyung Kang" . rdf:_1 ; rdf:_2 . tl:end "2012-04-19T15:30:00+02:00"^^ ; tl:start "2012-04-19T14:00:00+02:00"^^ . a foaf:Person ; rdfs:label "Pieter Colpaert" ; swrc:affiliation ; foaf:based_near ; foaf:firstName "Pieter" ; foaf:lastName "Colpaert" ; foaf:made ; foaf:mbox_sha1sum "513d030bd623fb5a5bb622d7ee66cf29a10c9340" ; foaf:name "Pieter Colpaert" . a swc:Presenter ; rdfs:label "Presenter of S2S Architecture and Faceted Browsing Applications" ; swc:heldBy ; swc:isRoleAt . a event:Event , swc:TutorialEvent ; rdfs:comment "Participants to the tutorial will learn how to build applications for mobile devices using Web technologies More Information" ; rdfs:label "W3C : Developing Mobile Web Applications" ; swc:hasLocation ; swc:isSubEventOf ; event:place ; event:time ; dce:description "Participants to the tutorial will learn how to build applications for mobile devices using Web technologies More Information" ; icaltzd:dtend "2012-04-17T12:30:00+02:00"^^ ; icaltzd:dtstart "2012-04-17T09:00:00+02:00"^^ ; icaltzd:location . a foaf:Person ; rdfs:label "Kevyn Collins-Thompson" ; swc:holdsRole ; swrc:affiliation ; foaf:based_near ; foaf:firstName "Kevyn" ; foaf:lastName "Collins-Thompson" ; foaf:mbox_sha1sum "b2e32ae1429ec0eb64cd1c605ac1c966b962b7b5" ; foaf:name "Kevyn Collins-Thompson" . a foaf:Person ; rdfs:label "Hakim Hacid" ; swc:holdsRole , ; swrc:affiliation , , ; foaf:based_near ; foaf:firstName "Hakim" ; foaf:lastName "Hacid" ; foaf:made , , , ; foaf:mbox_sha1sum "734997fc968525e4fa3bfba90735520cb23f0fd9" ; foaf:name "Hakim Hacid" . a foaf:Person ; rdfs:label "Minqi Zhou" ; swrc:affiliation ; foaf:based_near ; foaf:made ; foaf:mbox_sha1sum "ee240340fc4d3ca74f18c0d2dda1c9ff4d41e43d" ; foaf:name "Minqi Zhou" . rdf:_1 ; rdf:_2 . a swrc:InProceedings ; rdfs:label "Chinese News Event 5W1H Semantic Elements Extraction for Event Ontology Population" ; swc:isPartOf , ; dce:creator , ; dce:subject "ontology" , "5W1H" , "semantic role labeling" , "event extraction" ; dce:title "Chinese News Event 5W1H Semantic Elements Extraction for Event Ontology Population" ; bibo:authorList ; swrc:abstract "In order to relieve \"News Information Overload\", in this paper, we propose a novel approach of 5W1H (who, what, whom, when, where, how) event semantic elements extraction for Chinese news event knowledge base construction.

We first use a machine learning method to identify the key events of Chinese news stories. Then we employ SRL enhanced by rule-based method and NER technique to extract event 5W1H elements. At last we populate the extracted facts of news events to NOEM, an event ontology designed especially for modeling semantic elements and relations of events.

We present an approach to a priori population of such caches with Linked Data harvested from the Web, seeded by a simple context model for each user, which is progressively enriched by executing a series of enrichment rules over Linked Data from the Web. Such caches can act as personal data stores supporting a range of different applications.

Migrating web applications to Cloud services and integrating Cloud services into existing computing infrastructures is non-trivial. It leads to new challenges that often require innovation of paradigms and practices at all levels: technical, cultural, legal, regulatory, and social. The key problem in mapping Web applications to virtualized services in the Cloud is selecting the best and compatible mix of software images (e.g., Web server image) and infrastructure services to ensure that quality of service (QoS) targets of an application are achieved. The fact that, when selecting Cloud services, administrators must consider heterogeneous sets of criteria and complex dependencies between infrastructure services and software images, which are impossible to resolve manually, is a critical issue. To overcome these challenges, we present a generic decision making framework (called CloudGenius) which automates the decision-making process based on a model and factors specifically for Web server migration to the Cloud. CloudGenius leverages a well known multi-criteria decision making technique, called Analytic Hierarchy Process, to automate the selection process based on a model, factors, and QoS parameters related to an application. An example application demonstrates the applicability of the theoretical CloudGenius approach. Moreover, we present an implementation of CloudGenius that has been validated in experiments." ; swrc:month "April" ; swrc:year "2012" ; foaf:maker , . a swc:Presenter ; rdfs:label "Presenter of Serf and Turf: Crowdturfing for Fun and Profit" ; swc:heldBy ; swc:isRoleAt . rdf:_1 ; rdf:_2 ; rdf:_3 . a foaf:Organization ; rdfs:label "Gingertech" ; foaf:member ; foaf:name "Gingertech" . a foaf:Person ; rdfs:label "Alberto Messina" ; swrc:affiliation ; foaf:based_near ; foaf:firstName "Alberto" ; foaf:lastName "Messina" ; foaf:made ; foaf:mbox_sha1sum "2ceacd59e691d9d0c5d415efd5ccd2541ef3d5a0" ; foaf:name "Alberto Messina" . a event:Event , swc:TalkEvent ; rdfs:label "Paper presentation: Entity based Translation Language Model" ; swc:hasLocation ; swc:hasRelatedDocument ; swc:hasRole ; swc:isSubEventOf , ; event:agent ; event:place ; icaltzd:location ; icaltzd:summary "Paper presentation: Entity based Translation Language Model" . a foaf:Person ; rdfs:label "Andrzej Skrzypacz" ; swrc:affiliation ; foaf:based_near ; foaf:firstName "Andrzej" ; foaf:lastName "Skrzypacz" ; foaf:made ; foaf:mbox_sha1sum "816acb10db75277cf34e8b820ec486361c8ecc00" ; foaf:name "Andrzej Skrzypacz" . a foaf:Organization ; rdfs:label "University of Piraeus" ; foaf:member ; foaf:name "University of Piraeus" . a event:Event , swc:SessionEvent ; rdfs:comment "" ; rdfs:label "Posters - Natural Language Processing / Information Search and Retrieval" ; swc:hasLocation ; swc:isSuperEventOf , , , , , , , , , , , , , , , , , ; event:place ; event:time ; dce:description "" ; icaltzd:dtend "2012-04-19T17:30:00+02:00"^^ ; icaltzd:dtstart "2012-04-19T16:00:00+02:00"^^ ; icaltzd:location . a foaf:Organization ; rdfs:label "University College London" ; foaf:member , , , , , ; foaf:name "University College London" . a foaf:Organization ; rdfs:label "LIFL, University of Sciences and Technologies of Lille" ; foaf:member ; foaf:name "LIFL, University of Sciences and Technologies of Lille" . a foaf:Organization ; rdfs:label "Google Research" ; foaf:member , ; foaf:name "Google Research" . a foaf:Person ; rdfs:label "Manish Mohanlal" ; swrc:affiliation ; foaf:based_near ; foaf:firstName "Manish" ; foaf:lastName "Mohanlal" ; foaf:made ; foaf:mbox_sha1sum "f4d217cb712cec202c8c38b364b8f4b6e796f2fe" ; foaf:name "Manish Mohanlal" . a event:Event , swc:TutorialEvent ; rdfs:comment "Scalable data analysis has come a long way since the introduction of the MapReduce paradigm a decade ago.

Most existing systems are two-dimensional in that they only exploit User and Item dimensions and perform a typical form of recommendation ‘Recommending Item to User’. Yet, in many applications, the capabilities of dealing with multidimensional information and of adapting to various forms of recommendation requests are very important. In this paper, we take a graph-based approach to accomplishing such requirements in recommender systems and present a generic graph-based multidimensional recommendation framework. Based on the framework, we propose two homogeneous graph-based and one heterogeneous graph-based multidimensional recommendation methods. We expect our approach will be useful for increasing recommendation performance and enabling flexibility of recommender systems so that they can incorporate various user intentions into their recommendation process. We present our research result that we have reached and discuss remaining challenges and future work." ; swrc:year "2012" ; foaf:maker . a foaf:Person ; rdfs:label "Pavlos Fafalios" ; swc:holdsRole ;

dce:title "Answering math queries with search engines" ; bibo:authorList ; swrc:abstract "Conventional search engines such as Bing and Google provide a user with a short answer to some queries as well as a ranked list of documents, in order to better meet her information needs. In this paper we study a class of such queries that we call math. Arithmetic computations (e.g. ``square root of 123\"), unit conversions (e.g. \"convert 10 meter to feet\"), and symbolic computations (e.g. \"x\\^{}2+x+1=0\") are examples of math queries. Among the queries that should be answered, math queries are special because of the infinite combinations of numbers and symbols, and rather few keywords that make them up. Answering math queries must be done through real time computations rather than keyword searches or database look ups.The lack of a formal definition for the entire range of math queries makes it hard to automatically identify them all. We propose a novel approach for recognizing and classifying math queries using large scale search logs, and investigate its accuracy through empirical experiments and statistical analysis. It allows us to discover classes of math queries even if we do not know their structures in advance. It also helps to identify queries that are not math even though they might look like math queries. We also evaluate the usefulness of math answers based on the implicit feedback from users. Traditional approaches for evaluating the quality of search results, mostly rely on the click information and interpret a click on a link as a sign of satisfaction. Answers to math queries do not contain links, therefore such metrics are not applicable to them. In this paper we describe two evaluation metrics that can be applied for math queries, and present the results on a large collection of math queries taken from Bing's search logs." ; swrc:year "2012" ; foaf:maker , , . a foaf:Person ; rdfs:label "Zoltan Gyongyi" ; swc:holdsRole ; swrc:affiliation , ; foaf:based_near , ; foaf:made ; foaf:mbox_sha1sum "fa38ed4ef5eb6692c8f299bf26f7ab5042cc7034" , "97dd6ba9cbeb9e5fc1f22d98d32bab1b8f6fbefc" ; foaf:name "Zoltan Gyongyi" . a event:Event , swc:TalkEvent ; rdfs:label "Paper presentation: It's Simply Integral to What I do\": Enquiries into how the Web is Weaved into Everyday Life\"" ; swc:hasLocation ; swc:hasRelatedDocument ; swc:hasRole ; swc:isSubEventOf , ; event:agent ; event:place ; icaltzd:location ; icaltzd:summary "Paper presentation: It's Simply Integral to What I do\": Enquiries into how the Web is Weaved into Everyday Life\"" . a foaf:Organization ; rdfs:label "Kyungpook National University" ; foaf:member ; foaf:name "Kyungpook National University" . a foaf:Person ; rdfs:label "Marco Brambilla" ; swc:holdsRole , ; swrc:affiliation ; foaf:based_near , ; foaf:firstName "Marco" ; foaf:lastName "Brambilla" ; foaf:made , , ; foaf:mbox_sha1sum "e7a054c00b12c251d136955cc3059b5a59a0c583" ; foaf:name "Marco Brambilla" . rdf:_1 ; rdf:_2 ; rdf:_3 . a foaf:Organization ; rdfs:label "SITE, University of Ottawa" ; foaf:member ; foaf:name "SITE, University of Ottawa" . rdf:_1 ; rdf:_2 ; rdf:_3 . a foaf:Person ; rdfs:label "Andreas Harth" ; swc:holdsRole ; swrc:affiliation ; foaf:based_near ; foaf:firstName "Andreas" ; foaf:lastName "Harth" ; foaf:mbox_sha1sum "0604d144b935121a11d7495b2751e5d3176fc6fa" ; foaf:name "Andreas Harth" . a event:Event , swc:TalkEvent ; rdfs:label "Paper presentation: Information Integration Over Time in Unreliable and Uncertain Environments" ; swc:hasLocation ; swc:hasRelatedDocument ; swc:hasRole ; swc:isSubEventOf , ; event:agent ; event:place ; icaltzd:location ; icaltzd:summary "Paper presentation: Information Integration Over Time in Unreliable and Uncertain Environments" . a foaf:Person ; rdfs:label "Jun Han" ; swrc:affiliation ; foaf:based_near ; foaf:made ; foaf:mbox_sha1sum "09dc6ecfa517d798b20847d44712c36d15d49227" ; foaf:name "Jun Han" . a foaf:Organization ; rdfs:label "Ghent University" ; foaf:member ; foaf:name "Ghent University" . a foaf:Organization ; rdfs:label "NICTA" ; foaf:member , ; foaf:name "NICTA" . a foaf:Person ; rdfs:label "Cesare Pautasso" ; swc:holdsRole ; swrc:affiliation ; foaf:based_near , ; foaf:firstName "Cesare" ; foaf:lastName "Pautasso" ; foaf:made ; foaf:mbox_sha1sum "af2308705bed94be9df42b32943d498bb21a48d7" ; foaf:name "Cesare Pautasso" . a foaf:Person ; rdfs:label "Vasileios Mezaris" ; swrc:affiliation ; foaf:based_near ; foaf:firstName "Vasileios" ; foaf:lastName "Mezaris" ; foaf:made ; foaf:mbox_sha1sum "08f29a44b1785502782f98990acee6ed95f4d31d" ; foaf:name "Vasileios Mezaris" . a foaf:Person ; rdfs:label "Maja Vukovic" ; swrc:affiliation ; foaf:based_near ; foaf:made ; foaf:mbox_sha1sum "dc0e7adc0d1691170a7900360e9962e702482103" ; foaf:name "Maja Vukovic" . a swc:Presenter ; rdfs:label "Presenter of Identifying Sentiments over N-gram" ; swc:heldBy ; swc:isRoleAt . a foaf:Person ; rdfs:label "Marco Tagliasacchi" ; swrc:affiliation ; foaf:based_near ; foaf:firstName "Marco" ; foaf:lastName "Tagliasacchi" ; foaf:made ; foaf:mbox_sha1sum "407e6a580524885c321ac19ad6e8167a491b334c" ; foaf:name "Marco Tagliasacchi" . a foaf:Person ; rdfs:label "Sangrak Im" ; swrc:affiliation ; foaf:based_near ; foaf:made ; foaf:mbox_sha1sum "6c2b9215871ac6a9e3bcdb3decfc9de22064d301" ; foaf:name "Sangrak Im" . a foaf:Person ; rdfs:label "Jeffrey Naughton" ; swrc:affiliation ; foaf:based_near ; foaf:made ; foaf:mbox_sha1sum "e45dd197667c19acd17dec3614485795cce94cb6" ; foaf:name "Jeffrey Naughton" . a swc:Presenter ; rdfs:label "Presenter of Your Two Weeks of Fame and your Grandmother's" ; swc:heldBy ; swc:isRoleAt . a foaf:Person ; rdfs:label "Yong-Yeol Ahn" ; swc:holdsRole ; swrc:affiliation ; foaf:based_near ; foaf:firstName "Yong-Yeol" ; foaf:lastName "Ahn" ; foaf:mbox_sha1sum "2f258188a59ba0b00bb972631bbe82e4543abd9b" ; foaf:name "Yong-Yeol Ahn" . a foaf:Person ; rdfs:label "Pável Calado" ; swc:holdsRole ; swrc:affiliation ; foaf:based_near ; foaf:firstName "Pável" ; foaf:lastName "Calado" ; foaf:mbox_sha1sum "32d3d7f7b7e5034b7e6963916dc95bf792268ad9" ; foaf:name "Pável Calado" . a foaf:Person ; rdfs:label "Shou-De Lin" ; swrc:affiliation ; foaf:based_near ; foaf:made , , , , , ; foaf:mbox_sha1sum "7466e7341cfdad7e4153edb439fdfdb02003cad8" ; foaf:name "Shou-De Lin" . a event:Event , swc:TalkEvent ; rdfs:label "Paper presentation: Care to Comment?

E-Commerce search engines often have to deal with queries that cannot be easily matched to product inventory resulting in zero recall or null query situations. Null query arise from differences in buyer and seller vocabulary or from the transient nature of products. In this paper, we describe a system that rewrites null e-commerce queries to find matching products as close to the original query as possible. The system uses query relaxation to rewrite null queries in order to match products. Using eBay as an example of a dynamic marketplace, we show how using temporal feedback that respects product category structure using the repository of expired products we improve the quality of recommended results. The system is scalable and can be run in a high volumesetting. We show through our experiments that high quality product recommendations for more than 25% of null queries is achievable." ; swrc:year "2012" ; foaf:maker , , . a swrc:InProceedings ; rdfs:label "Fixing the Web one page at a time, or actually implementing xkcd #37" ; swc:isPartOf , ; dce:creator , , ; dce:subject "xkcd" , "grammar" , "browser extensions" , "typography" ; dce:title "Fixing the Web one page at a time, or actually implementing xkcd #37" ; bibo:authorList ; swrc:abstract "Albeit famous exceptions exist in form of Wikis, the Web today is still mostly a read-only experience.

While fighting the cause, namely sloppy Web authors, is like a fight against wind mills and certainly impossible to realize on Web scale, fighting the symptoms is a realistic option. Using client-side work-arounds, the Web can actually be fixed one page at a time.

We discuss our experience building the system and provide assessment of the accuracy of its real-time detection and alert mechanisms." ; swrc:year "2012" ; foaf:maker , , , , , . tl:end "2012-04-18T18:00:00+02:00"^^ ; tl:start "2012-04-18T16:00:00+02:00"^^ . a foaf:Person ; rdfs:label "Stephane Lavirotte" ; swc:holdsRole ; swrc:affiliation ; foaf:based_near ; foaf:mbox_sha1sum "97dd6ba9cbeb9e5fc1f22d98d32bab1b8f6fbefc" ; foaf:name "Stephane Lavirotte" . tl:end "2012-04-16T17:30:00+02:00"^^ ; tl:start "2012-04-16T09:00:00+02:00"^^ . a event:Event , swc:TalkEvent ; rdfs:label "Paper presentation: Populating Personal Linked Data Caches using Context Models" ; swc:hasLocation ; swc:hasRelatedDocument ; swc:hasRole ; swc:isSubEventOf , ; event:agent ; event:place ; icaltzd:location ; icaltzd:summary "Paper presentation: Populating Personal Linked Data Caches using Context Models" . a foaf:Person ; rdfs:label "Peter Lambert" ; swrc:affiliation ; foaf:based_near ; foaf:firstName "Peter" ; foaf:lastName "Lambert" ; foaf:made ; foaf:mbox_sha1sum "abefef6c14d84a0ef95dfc02ef042539b1297b25" ; foaf:name "Peter Lambert" . rdf:_1 ; rdf:_2 ; rdf:_3 ; rdf:_4 . a foaf:Person ; rdfs:label "Mirjam Wattenhofer" ; swrc:affiliation ; foaf:based_near ; foaf:firstName "Mirjam" ; foaf:lastName "Wattenhofer" ; foaf:made ; foaf:mbox_sha1sum "bc130d803e5a9c62cc5bdfc43a5763666c399d5f" ; foaf:name "Mirjam Wattenhofer" . a foaf:Person ; rdfs:label "Harald Sack" ; swc:holdsRole ; swrc:affiliation ; foaf:based_near ; foaf:firstName "Harald" ; foaf:lastName "Sack" ; foaf:mbox_sha1sum "4d582458728456ce41559e03c6b992bf68a8268d" ; foaf:name "Harald Sack" . a swc:Presenter ; rdfs:label "Presenter of Review Spam Detection via Time Series Pattern Discovery" ; swc:isRoleAt . tl:end "2012-04-19T17:30:00+02:00"^^ ; tl:start "2012-04-19T16:45:00+02:00"^^ . a foaf:Person ; rdfs:label "David Hawking" ; swc:holdsRole ; swrc:affiliation ; foaf:based_near ; foaf:firstName "David" ; foaf:lastName "Hawking" ; foaf:mbox_sha1sum "de76d9bd65b97e4798ce4f386fb5176a35c33f94" ; foaf:name "David Hawking" . a foaf:Person ; rdfs:label "Edward Bortnikov" ; swrc:affiliation ; foaf:based_near , ; foaf:firstName "Edward" ; foaf:lastName "Bortnikov" ; foaf:made , ; foaf:mbox_sha1sum "3c944e179b693dbac059a9e2677213f754366b27" ; foaf:name "Edward Bortnikov" . a foaf:Person ; rdfs:label "Parag Joshi" ; swc:holdsRole ; swrc:affiliation ; foaf:based_near ; foaf:firstName "Parag" ; foaf:lastName "Joshi" ; foaf:made ; foaf:mbox_sha1sum "8f5592b0006c11eccd08caa4c6e39d2516a959a7" ; foaf:name "Parag Joshi" . a swc:Presenter ; rdfs:label "Presenter of Ubiquitous Access Control for SPARQL Endpoints: Lessons Learned and Future Challenges" ; swc:heldBy ; swc:isRoleAt . a foaf:Person ; rdfs:label "Roberto Del Pero" ; swrc:affiliation ; foaf:based_near ; foaf:firstName "Roberto" ; foaf:lastName "Del Pero" ; foaf:made ; foaf:mbox_sha1sum "9495407f2ebb27466b07702afb6b7f37cccc71fc" ; foaf:name "Roberto Del Pero" . a foaf:Person ; rdfs:label "Bernhard Krüpl" ; swc:holdsRole ; swrc:affiliation ; foaf:based_near ; foaf:mbox_sha1sum "97dd6ba9cbeb9e5fc1f22d98d32bab1b8f6fbefc" ; foaf:name "Bernhard Krüpl" . a foaf:Person ; rdfs:label "Kaushik Chakrabarti" ; swc:holdsRole ; swrc:affiliation ; foaf:based_near ; foaf:firstName "Kaushik" ; foaf:lastName "Chakrabarti" ; foaf:made ; foaf:mbox_sha1sum "c9dcca51b4a10b9092c39afeb439dbd45e22e601" ; foaf:name "Kaushik Chakrabarti" . a event:Event , swc:TalkEvent ; rdfs:label "Paper presentation: Cross-lingual Knowledge Linking Across Wiki Knowledge Bases" ; swc:hasLocation ; swc:hasRelatedDocument ; swc:hasRole ; swc:isSubEventOf , ; event:agent ; event:place ; icaltzd:location ; icaltzd:summary "Paper presentation: Cross-lingual Knowledge Linking Across Wiki Knowledge Bases" . rdf:_1 ; rdf:_2 ; rdf:_3 ; rdf:_4 ; rdf:_5 ; rdf:_6 . a event:Event , swc:TalkEvent ; rdfs:label "Paper presentation: Fast Query Evaluation for Ad Retrieval" ; swc:hasLocation ; swc:hasRelatedDocument ; swc:hasRole ; swc:isSubEventOf , ; event:agent ; event:place ; icaltzd:location ; icaltzd:summary "Paper presentation: Fast Query Evaluation for Ad Retrieval" . a foaf:Organization ; rdfs:label "Ontotext AD" ; foaf:member ; foaf:name "Ontotext AD" . a swrc:InProceedings ; rdfs:label "Towards Expressive Exploratory Search Over Entity-Relationship Data" ; swc:isPartOf , ; dce:creator , , , ; dce:subject "Interactive Querying" , "Entity-relationship data" , "Exploratory search" ; dce:title "Towards Expressive Exploratory Search Over Entity-Relationship Data" ; bibo:authorList ; swrc:abstract "In this paper we describe a novel approach for exploratory searchover rich entity-relationship data that utilizes a uniquecombination of expressive, yet intuitive, query language, facetedsearch, and graph navigation.

Betweenness centrality is widely used in network analyses. Especially in a social network, the recursive computation of betweenness centrality of vertices is performed for the community detection and finding the influential user in the network. Since a social network graph is frequently updated, it is necessary to update the betweenness centrality efficiently. To the best of our knowledge, this is the first work that proposes an algorithm which updates the betweenness centrality of all vertices in a graph efficiently. When a graph is changed, betweenness centerality of all vertices should be recomputed from the scratch using all the vertices of the graph. In this paper, we propose a method that efficiently reduces the search space by finding a candidate set of vertices whose betweenness centrality can be updated and computes their betweenness centeralities using candidate vertices only. As the cost of calculating betweenness centrality mainly depends on the number of vertices to be considered, the proposed algorithm significantly reduces the cost of calculation. Experiments on large datasets show that our algorithm outperforms an adapted existing algorithm in updating the betweenness centrality of vertices." ; swrc:month "April" ; swrc:year "2012" ; foaf:maker , , , , . a foaf:Person ; rdfs:label "Mária Bieliková" ; swc:holdsRole ; swrc:affiliation ; foaf:based_near ; foaf:firstName "Mária" ; foaf:lastName "Bieliková" ; foaf:mbox_sha1sum "7af54485f79dc9f445d927f4ed914c731c10a661" ; foaf:name "Mária Bieliková" . a event:Event , swc:TalkEvent ; rdfs:label "Paper presentation: Detecting Dynamic Association among Twitter Topics" ; swc:hasLocation ; swc:hasRelatedDocument ; swc:hasRole ; swc:isSubEventOf , ; event:agent ; event:place ; icaltzd:location ; icaltzd:summary "Paper presentation: Detecting Dynamic Association among Twitter Topics" . a foaf:Person ; rdfs:label "Nenghai Yu" ; swrc:affiliation ; foaf:based_near ; foaf:firstName "Nenghai" ; foaf:lastName "Yu" ; foaf:made ; foaf:mbox_sha1sum "abf454c6093b5705c1d0f26df48d4c97b457d438" ; foaf:name "Nenghai Yu" . a foaf:Person ; rdfs:label "Kimberly Paterson" ; swrc:affiliation ; foaf:based_near ; foaf:firstName "Kimberly" ; foaf:lastName "Paterson" ; foaf:made ; foaf:mbox_sha1sum "07991eea1037519baa8e6877d662e32ae36bb7e5" ; foaf:name "Kimberly Paterson" . a foaf:Person ; rdfs:label "Vanja Josifovski" ; swc:holdsRole ; swrc:affiliation , ; foaf:based_near , ; foaf:firstName "Vanja" ; foaf:lastName "Josifovski" ; foaf:made , ; foaf:mbox_sha1sum "60fbd2675a6409936ad802b37ec5c45d3ca58860" ; foaf:name "Vanja Josifovski" . a foaf:Person ; rdfs:label "Jingbin Wang" ; swrc:affiliation ; foaf:based_near ; foaf:made ; foaf:mbox_sha1sum "ea0c56d38b0038d7e81a6f92650fc66e14036679" ; foaf:name "Jingbin Wang" . a event:Event , swc:TalkEvent ; rdfs:label "Paper presentation: Declarative Platform for Data Sourcing Games" ; swc:hasLocation ; swc:hasRelatedDocument ; swc:hasRole ; swc:isSubEventOf , ; event:agent ; event:place ; icaltzd:location ; icaltzd:summary "Paper presentation: Declarative Platform for Data Sourcing Games" . a foaf:Organization ; rdfs:label "National Institute of Informatics and The Univeristy of Tokyo" ; foaf:member ; foaf:name "National Institute of Informatics and The Univeristy of Tokyo" . a foaf:Organization ; rdfs:label "Univ Paris Diderot, Sorbonne Paris Cité, PPS, UMR 7126 CNRS, INRIA" ; foaf:member ; foaf:name "Univ Paris Diderot, Sorbonne Paris Cité, PPS, UMR 7126 CNRS, INRIA" . a foaf:Person ; rdfs:label "Xin Fan" ; swrc:affiliation ; foaf:based_near ; foaf:firstName "Xin" ; foaf:lastName "Fan" ; foaf:made ; foaf:mbox_sha1sum "33a3949dee42aa5c7bde317aa6687e359a426024" ; foaf:name "Xin Fan" . a foaf:Person ; rdfs:label "FabianM.

Tools used currently by Web archivists blindly crawl and store Web pages found while crawling, disregarding the kind of Web site currently accessed (which leads to suboptimal crawling strategies) and whatever structured content is contained in Web pages (which results in page-level archives whose content is hard to exploit). We focus in this PhD work in the crawling and archiving of publicly accessible Web applications, especially those of the social Web. A Web application is any application that uses Web standards such as HTML and HTTP to publish information on the Web, accessible by Web browsers. Examples include Web forums, social networks, geolocation services, etc. We claim that the best strategy to crawl these applications is to make the Web crawler aware of the kind of application currently processed, allowing it to refine the list of URLs to process, and to annotate the archive with information about the structure of crawled content. We add adaptive characteristics to an archiving Web crawler: being able to identify when a Web page belongs to a given Web application and applying the appropriate crawling and content extraction methodology.""" ; swrc:year "2012" ; foaf:maker . a foaf:Person ; rdfs:label "Olivier Corby" ; swc:holdsRole ; swrc:affiliation ; foaf:based_near ; foaf:firstName "Olivier" ; foaf:lastName "Corby" ; foaf:mbox_sha1sum "a2ecfefc77044a9ab7c10f404c277ae9fab49e22" ; foaf:name "Olivier Corby" . a foaf:Organization ; rdfs:label "University of Delaware" ; foaf:member , , ; foaf:name "University of Delaware" . a foaf:Organization ; rdfs:label "City University of New York" ; foaf:member ; foaf:name "City University of New York" . a foaf:Person ; rdfs:label "Jingtian Jiang" ; swrc:affiliation ; foaf:based_near ; foaf:firstName "Jingtian" ; foaf:lastName "Jiang" ; foaf:made ; foaf:mbox_sha1sum "a43dcba0a42d4ae99b1bdad82958584127ba386f" ; foaf:name "Jingtian Jiang" . rdf:_1 ; rdf:_2 ; rdf:_3 ; rdf:_4 . a swrc:InProceedings ; rdfs:label "Let Google Index Your Media Fragment" ; swc:isPartOf , ; dce:creator , , ; dce:subject "microdata" , "annotation" , "media fragment" , "Google search" ; dce:title "Let Google Index Your Media Fragment" ; bibo:authorList ; swrc:abstract "Current multimedia applications in Web 2.0 have generated massive amount of multimedia resources, but most search results for multimedia resources still stay on the whole resource level.

This results in an undesirable scenario where these offensive comments are the top rated ones. In this paper, we develop semi-supervised learning techniques to correct the bias in user ratings of comments. Our scheme uses a small number of comment labels in conjunction with user rating information to iteratively compute user bias and true ratings for unlabeled comments. We show that the running time of each iteration is linear in the number of ratings, and the system converges to a unique fixed point. To select the comments to label, we devise an active learning algorithm based on Empirical risk minimization. Our active learning method incrementally updates the risk for neighboring comments each time a comment is labeled, and thus can easily scale to large comment datasets. On real-life comments from Yahoo! News, our semi-supervised and active learning algorithms achieve higher accuracy than simple baselines, with few labeled examples." ; swrc:month "April" ; swrc:year "2012" ; foaf:maker , . a foaf:Person ; rdfs:label "Daniel Muller" ; swc:holdsRole ; swrc:affiliation ; foaf:based_near ; foaf:firstName "Daniel" ; foaf:lastName "Muller" ; foaf:mbox_sha1sum "1dd07ee4f5b4a7a5fd52bb3d7f4d48e5e83a904b" ; foaf:name "Daniel Muller" . a event:Event , swc:SessionEvent ; rdfs:comment "Annotation" ; rdfs:label "PhD Symposium S1 - Annotation" ; swc:hasLocation ; swc:isSuperEventOf , , ; event:place ; event:time ; dce:description "Annotation" ; icaltzd:dtend "2012-04-18T15:30:00+02:00"^^ ; icaltzd:dtstart "2012-04-18T14:00:00+02:00"^^ ; icaltzd:location . a foaf:Person ; rdfs:label "Szabolcs Grünwald" ; swrc:affiliation ; foaf:based_near ; foaf:firstName "Szabolcs" ; foaf:lastName "Grünwald" ; foaf:made ; foaf:mbox_sha1sum "1696c988614f074ccb38ee920a0876a31e16d3ed" ; foaf:name "Szabolcs Grünwald" . a foaf:Person ; rdfs:label "Shlomo Berkovsky" ; swrc:affiliation ; foaf:based_near ; foaf:made ; foaf:mbox_sha1sum "aba12ab620177813d7639bc5d7d835f9ac18bd05" ; foaf:name "Shlomo Berkovsky" . a foaf:Organization ; rdfs:label "The Robert Gordon University" ; foaf:member ; foaf:name "The Robert Gordon University" . a foaf:Organization ; rdfs:label "Univ Oxford" ; foaf:member ; foaf:name "Univ Oxford" . a swrc:InProceedings ; rdfs:label "Analyzing Spammers' Social Networks For Fun and Profit -- A Case Study of Cyber Criminal Ecosystem on Twitter" ; swc:isPartOf ; dce:creator , , , , ; dce:subject "Cyber criminal" , "Twitter" , "Ecosystem" ; dce:title "Analyzing Spammers' Social Networks For Fun and Profit -- A Case Study of Cyber Criminal Ecosystem on Twitter" ; bibo:authorList ; swrc:abstract "In this paper, we perform an empirical analysis of the cyber criminal ecosystem on Twitter.

Through analyzing outer social relationships between the criminal account community and criminal supporter community, we find three types of criminal supporters that have close friendships with criminal accounts.

These are often only informally described, may contain errors, lack harmonization, and generally speaking make the developer’s work difficult. Most attempts to solve this problem, proposing formal description languages for Web service APIs, have had limited success outside of B2B applications; we believe it is due to their top-down nature. In addition, a programmer dealing with one or several of these APIs has to deal with a number of related tasks such as data integration, requests chaining, or policy management, that are cumbersome to implement. Inspired by the SPORE project, we present API Blender, an open-source solution to describe, interact with, and integrate the most common social Web APIs. In this perspective, we first introduce two new lightweight description formats for requests and services and demonstrate their relevance with respect to current platform APIs. We present our Python implementation of API Blender and its features regarding authentication, policy management, multi-platform data integration." ; swrc:year "2012" ; foaf:maker , . a swc:Presenter ; rdfs:label "Presenter of Care to Comment?

Thus, in some contexts one might feel complimented to be described as cunning or aggressive, but feel aggrieved and insulted to be so described in another. As concepts become more complex and multifaceted, and accrete more layers of stereotypical associations, their ability to assume different affective profiles in different contexts also increases. We therefore propose a two-level organization for the affective lexicon: at the first level, concepts are associated with a nuanced description of their stereotypical behaviors, as learned from the Web; at the second level, these behaviors are assigned an affective profile. This two-level lexicon, called MOODprism, acts as a foundation for the demonstration system described in this paper. The system, named MOODfinger, is an affective search engine for news content that is harvested from the Web. We describe here the kinds of affective queries that are supported.

Accessing a wider pool of user feedback leads to an increasingly more accurate analysis of user tastes, effectively creating a ``rich get richer'' effect. This work aims at significantly lowering the entry barrier for creating music recommenders, through a paradigm coupling a public data source and a new collaborative filtering (CF) model. We claim that Internet radio stations form a readily available resource of abundant fresh human signals on music through their playlists, which are essentially cohesive sets of related tracks. In a way, our models rely on the knowledge of a diverse group of experts in lieu of the commonly used wisdom of crowds. Over several weeks, we aggregated publicly available playlists of thousands of Internet radio stations, resulting in a dataset encompassing millions of plays, and hundreds of thousands of tracks and artists. This provides the large scale ground data necessary to mitigate the cold start problem of new items at both mature and emerging services. Furthermore, we developed a new probabilistic CF model, tailored to the Internet radio resource. The success of the model was empirically validated on the collected dataset. Moreover, we tested the model at a cross-source transfer learning manner - the same model trained on the Internet radio data was used to predict behavior of Yahoo! Music users. This demonstrates the ability to tap the Internet radio signals in other music recommendation setups. Based on encouraging empirical results, our hope is that the proposed paradigm will make quality music recommendation accessible to all interested parties in the community." ; swrc:month "April" ; swrc:year "2012" ; foaf:maker , , . a foaf:Organization ; rdfs:label "Accademia Nazionale di Santa Cecilia" ; foaf:member ; foaf:name "Accademia Nazionale di Santa Cecilia" . rdf:_1 ; rdf:_2 ; rdf:_3 ; rdf:_4 ; rdf:_5 ; rdf:_6 . a swrc:InProceedings ; rdfs:label "Visual OXPath: Robust Wrapping by Example" ; swc:isPartOf , ; dce:creator , , , , ; dce:subject "Web automation" , "AJAX" , "XPath" , "Web extraction" ; dce:title "Visual OXPath: Robust Wrapping by Example" ; bibo:authorList ; swrc:abstract """Good examples are hard to find, particularly in wrapper induction: Picking even one wrong example can spell disaster by yielding overgeneralized or overspecialized wrappers.

To ease wrapper refinement, it offers a list of wrappers ranked by example similarity and robustness. Visual OXPath offers ex- tensive visual feedback for this refinement which can be performed without any knowledge of the underlying wrapper language.

Though modern web browsers provide facilities to assist in form filling, this assistance is limited to prior form fillings or keyword matching. Automatic form understanding enables a broad range of applications, including crawlers, meta-search engines, and usability and accessibility support for enhanced web browsing. In this demonstration, we use a novel form understanding approach, OPAL, to assist in form filling even for complex, previously unknown forms. OPAL associates form labels to fields by analyzing structural properties in the HTML encoding and visual features of the page rendering. OPAL interprets this labeling and classifies the fields according to a given domain ontology. The combination of these two properties, allows OPAL to deal effectively with many forms outside of the grasp of existing form filling techniques. In the UK real estate domain, OPAL achieves > 99% accuracy in form understanding.""" ; swrc:year "2012" ; foaf:maker , , , , , . a foaf:Organization ; rdfs:label "Facebook, Inc" , "Facebook" ; foaf:member , , , ; foaf:name "Facebook, Inc" , "Facebook" . a event:Event , swc:TalkEvent ; rdfs:label "Paper presentation: A Generic Graph-based Multidimensional Recommendation Framework and Its Implementations" ; swc:hasLocation ; swc:hasRelatedDocument ; swc:hasRole ; swc:isSubEventOf , ; event:agent ; event:place ; icaltzd:location ; icaltzd:summary "Paper presentation: A Generic Graph-based Multidimensional Recommendation Framework and Its Implementations" . a swrc:InProceedings ; rdfs:label "SnoopyTagging: Recommending Contextualized Tags to Increase the Quality and Quantity of Meta-Information" ; swc:isPartOf , ; dce:creator , , , ; dce:subject "Heterogeneity" , "Recommender Systems" , "Tagging" , "Tags" , "Structure" ; dce:title "SnoopyTagging: Recommending Contextualized Tags to Increase the Quality and Quantity of Meta-Information" ; bibo:authorList ; swrc:abstract "Current mass-collaboration platforms use tags to annotate and categorize resources enabling effective search capabilities.

Another shortcoming of simple tags is that they do not allow for a specification of context to create meaningful metadata.
