  abstract =	 {Social media systems such as weblogs, photo- and
                  linksharing sites, wikis and on-line forums are
                  currently thought to produce up to one third of new
                  Web content. One thing that sets these ``Web 2.0''
                  sites apart from traditional Web pages and resources
                  is that they are intertwined with other forms of
                  networked data. Their standard hyperlinks are
                  enriched by social networks, comments, trackbacks,
                  advertisements, tags, RDF data and metadata. We
                  describe recent work on building systems that use
                  models of the Blogosphere to recognize spam blogs,
                  find opinions on topics, identify communities of
                  interest, derive trust relationships, and detect
                  influential bloggers.},
