However, knowledge gathered from online sources and social media comes with a major caveat - it cannot always be trusted, nor is it always factual and of high quality. Rumors tend to spread rapidly through social networks, especially in circumstances where their veracity is hard to establish. Researchers have found that people read and rely on untrusted sources for various reasons, the main ones being their interestingness, entertainment value, a friend's online recommendation, or a search engine result. A 2012 report from Pew Internet Research on the future of big data argues that even though by 2020 big data is likely to have a transformational effect on our knowledge and understanding of the world, there is also high risk of "distribution of harms" due to the abundance of inaccurate and false information.</div><div><br></div><div>This special issue will focus on the problem of modelling and assessing the trust and veracity of content and information posted in social media, including but not limited to automatic detection, tracking, and visualization of deceptive content, rumors and malicious campaigns, and their spread across media, languages and social networks. The aim of this multidisciplinary special issue is to bring together researchers from Information Retrieval, Web Science, Data Mining, Social Network Analysis, Social Computing, Information Visualization, Natural Language Processing, Multimedia and Human-Computer Interaction, and to combine perspectives and research from Computer Science and Sociology.</div><div><br></div><div><br></div><div>Scope & Topics of Interest</div><div><br></div><div>While all high-quality manuscripts focused on trust and veracity of information will be considered, we are particularly interested in approaches, applications and case studies with a focus on social media, including online social networks (Twitter, Facebook, Google+, LinkedIn), media sharing applications (Flickr, Instagram, YouTube, DailyMotion, Vine, Imgur), social news (Reddit, Fark, Slashdot), blogging (Tumblr, Blogger), question-answering and knowledge exchange applications (Quora, StackExchange), location-based social networks (Foursquare), reviewing sites (epinions, yelp, TripAdvisor), collaborative authoring environments (Wikipedia), social bookmarking and tagging (Pinterest, StumbleUpon, delicious), and other applications and platforms extensively based on user-generated content and feedback (referred to simply as "social media" below for brevity). Topics of interest include, but are not limited to, the following:</div><div><br></div><div>- Detection of rumors, misinformation, tampered content and spam in social media;</div><div>- Propagation of rumors and deceptive content within and across social networks;</div><div>- Modelling social network user and information source trustworthiness;</div><div>- Methods of quantifying trust and reliability of shared information and content;</div><div>- Identifying false claims and manipulations in user-generated content;</div><div>- Using inference and machine learning to distinguish between rumors and facts;</div><div>- Identifying false claims and manipulations in user-generated content;</div><div>- Qualitative studies of rumors and deception in social media;</div><div>- Using Linked Open Data as a factual knowledge source;</div><div>- Spatio-temporal grounding of rumors and deceptive content;</div><div>- Annotation schemas and evaluation of trust, rumor and misinformation detection;</div><div>- Visualization of rumor propagation and spheres of influence;</div><div>- Case studies of rumor and deception detection as currently practiced in real-world settings (e.g., digital journalism, crisis response, public order situations);</div><div>- Applications of rumor and deception detection methods and tools to real-world problems (e.g., digital journalism, crisis response, environmental communication).</div><div><br></div><div>All accepted manuscripts are expected to make a significant scientific contribution and present a rigorous evaluation of the methods they present (e.g., a comprehensive user study should accompany any new visualization proposal).</div><div><br></div><div><br></div><div>Submission</div><div><br></div><div>For submission instructions and reviewing procedure, please refer tohttp://<a href="http://tois.acm.org/authors.html">tois.acm.org/authors.html</a> and add a comment in the email to the Assistant to the Editor-In-Chief that the submission is intended for the special issue on Trust and Veracity of Information in Social Media. All papers will be reviewed by three external reviewers plus at least one guest editor.</div><div><br></div><div><br></div><div>Important Dates</div><div><br></div><div>Paper Submission Deadline: Mar 24, 2015</div><div>Notification to Authors (first round): Jun 23, 2015</div><div>Articles invited to revise for reconsideration due: Aug 18, 2015</div><div>Final Notification to authors: Oct 27, 2015</div><div>Camera-ready articles due: Nov 17, 2015</div><div><br></div><div><br></div><div>Guest Editors</div><div><br></div><div>Kalina Bontcheva, University of Sheffield, UK (Primary <a href="mailto:Contact%3Ak.bontcheva@dcs.shef.ac.uk">Contact:k.bontcheva@dcs.shef.ac.uk</a>)</div><div>Symeon Papadopoulos, CERTH-ITI, Greece (Primary <a href="mailto:Contact%3Apapadop@iti.gr">Contact:papadop@iti.gr</a>)</div><div>Eva Jaho, Athens Technology Center (ATC), Greece</div><div>Rob Procter, University of Warwick, UK</div><div>Mihai Lupu, Vienna University of Technology, Austria</div><div>Carlos Castillo, Qatar Computing Research Institute, Qatar</div></div>
