Searching User Generated Content: What's Next?

In recent years, blog search has received a lot of attention. Since the launch of dedicated evaluation efforts and the release of blog data sets, our understanding of blog search has deepened considerably.

In this talk, a number of user generated content search scenarios from the media analysis and intelligence domains will be detailed. From these, recurring themes such as credibility, people finding, impact prediction, unusual event detection, report and summary generation--all on user generated content--will be identified as highly relevant research directions.
