Social media systems such as weblogs, photo and link sharing sites, wikis and on-line forums are estimated to produce up to one third of new Web content. Several things set these "Web 2.0" sites apart from traditional Web pages and resources: they are often annotated with semantic metadata, they are intertwined with human social networks and their constituent parts exhibit a rich set of relations and connections through comments, trackbacks, advertisements, tags, and other metadata. Developing models of these new information sources, understanding how to manage them, and developing techniques to extract useful information from them are topics of keen interest...Topics will include but are not limited to issues such as graph analysis, trust and reputation in open media, data mining of social media, crawling and indexing, ranking and influence measurement of blogs/bloggers, cross media link detection and analysis, opinion and sentiment detection, measuring and predicting social media phenomenon such as "buzz spread", metadata detection topic detection and tracking.
