Bob ----------------------------------- *Call for Workshop Papers and Extended Abstracts* *Workshop on Wikipedia, a Social Pedia: Research Challenges and Opportunities* May 26, Oxford, England co-located with the 9th International Conference on Weblogs and Social Media (ICWSM 2015) http://snap.stanford.edu/wiki-icwsm15/ Deadline for submissions: Tuesday, March 31, 2015, 23:59 AoE Wikipedia is one of the most popular sites on the Web, a main source of knowledge for a large fraction of Internet users, and, in the light of its collaborative nature, an inherently social medium. Therefore, and since not only all content but also many activity logs are available to the public, Wikipedia has become an important object of study for researchers across many subfields of the computational and social sciences, such as social-network analysis, social psychology, education, anthropology, political science, human-computer interaction, cognitive science, artificial intelligence, linguistics, and natural-language processing. This workshop is a venue for all researchers exploring social aspects of Wikipedia. The workshop will feature high-profile speakers from academia and the Wikimedia Foundation and aims to create a forum where participants can connect both among each other and with researchers at the Wikimedia Foundation. Topics of interest include, but are not limited to: - Collaborative content creation - Consensus-finding and conflict resolution on editorial issues - Content consumption on Wikipedia - Participation in discussions and their dynamics - Collaborative task management - Evolution of hierarchies - Wikipedia as a sensor for real-world events, culture, etc. - Demographics of Wikipedia readers and editors - Engagement and incentivization of editors - ... Papers should be 2 to 8 pages long. Authors whose papers are accepted to the workshop will have the opportunity to participate in a poster session. We especially encourage the submission of preliminary work in the form of extended abstracts. *Submission instructions* Papers should be formatted according to AAAI formatting guidelines ( http://www.aaai.org/Publications/Author/author.php). Please submit papers using EasyChair at https://easychair.org/conferences/?conf=wikiicwsm2015 *Review and the archival of papers* Authors will be notified of acceptance or rejection on or before Sat, April 4, 2015. Accepted papers will be published on the workshop webpage and in a AAAI technical report. (The tech report is non-archival, so the authors are free to submit their work to other venues; inclusion in the tech report is optional.) Also, authors whose papers are accepted will have the opportunity to participate in a poster session. *Organizing committee* Robert West, Stanford University Jure Leskovec, Stanford University Leila Zia, Wikimedia Foundation
