The quality of user-generated content in Web 2.0 dramatically varies from professional to abusive.

On the other hand, the insights that could be gained by a large-scale analysis of social media argumentation make it a very worthwhile task. In this position paper I discuss the motivatio...

This paper asks whether unpopular tail items in usergenerated content corpora are important, and how tail items differ from the popular head items. We develop a user-centric characterisation of the tail which shows that although the head receives a disproportionate share of interest, tail items collectively serve a large number of users. “Tail seekers”, with more ‘like’s in the tail than the he...
