Web 2.0 Mining: Analyzing Social Media

Social media systems such as blogs, photo and link sharing sites, wikis and on-line forums are estimated to produce up to one third of new Web content. One thing that sets these "Web 2.0" sites apart from tradi- tional Web pages and resources is that they are inter- twined with other forms of networked data. Their stan- dard hyperlinks are enriched by social networks, com- ments, trackbacks, advertisements, tags, RDF data and metadata. We describe recent work on building systems that analyse these emerging social media systems to rec- ognize spam blogs, find opinions on topics, identify com- munities of interest, derive trust relationships, and de- tect influential bloggers.
