Second Workshop on Social News on the Web (SNOW 2014) Co-located with WWW '14, Seoul, Korea Apr 7th 2014 http://www.snow-workshop.org/2014/ Call for Papers: The workshop provides a forum for presenting novel ideas and discussing future directions in the emerging areas of news search, news mining, and news recommendation. It especially focuses on the interplay between news content, generated by professional journalists, and social-media content, generated by millions of users in real-time and subject to social-media dynamics. We also invite contributions on modeling and leveraging user feedback related to news content, as well as contributions on mining news comments. Furthermore, we invite contributions on the more ambitious topics of citizen journalism and computational journalism. The former studies how citizens can collaborate to collect information, synthesize, edit, verify, and produce their own news stories in a wiki-type paradigm. The latter investigates the use of analysis of web data by professional journalists as an integral part of the news creation process. Finally, we will also set up a challenge on breaking news detection from social media streams, with prizes for the winners. The challenge organization will be supported by the SocialSensor EU project, that in the last two years has focused on the discovery of interesting social content and its integration in the news creation and delivery lifecycle. Topics of interest: The relevant topics of interest for SNOW include but are not limited to: • Summarization, exploration, and visualization of news • News content verification • Information retrieval in news collections • Personalized news recommendation • Detection of breaking news and events from social streams • Tracking of news evolution • Modeling of news readers • Modeling of news propagation on social networks • Modeling trust and authority of news sources • Retrieval and mining of multimedia objects related to news • Multimedia geotagging and geographical mining related to news • Studying the interplay between news and web-usage data • Studying the interplay between news and social-media data • Mining news comments, sentiment and opinion • Citizen journalism and wiki-news • Platforms and services for computational journalism • News and mobile computing The major criteria for the selection process of papers will be their potential to generate discussion and influence future research directions. Deadlines: • Paper submission: Jan 14, 2014 (23:59 Hawaii Standard Time) • Acceptance notification: Jan 24, 2014 • Camera-ready version: Feb 12, 2014 Paper submission: Two different types of contributions will be considered: • Full research papers (8 pages max) • Position papers (4 pages max) In the spirit of the workshop theme, the acceptance of papers will be conditioned to the submission of a blog entry (that will be eventually posted on the workshop website) describing the research carried out in a non-technical style. The purpose is to reach outside the computer-science community and make the latest results on computer-based journalism known to a broader audience. The papers should be formatted using the standard ACM conference format, with a two-column layout and must be submitted electronically in printable PDF format. Papers have to present original research contributions not concurrently submitted elsewhere Paper submission is single blind and will be handled via EasyChair. We will tentatively invite the best submissions to extend their papers in order to be published on a special issue of a journal.
