We describe an ongoing effort to collect and annotate very large corpora of user-contributed content in multiple languages for the DARPA BOLT program, which has among its goals the development of genre-independent machine translation and information retrieval systems. Initial work includes collection of several hundred million words of online discussion forum threads in English, Chinese and Egy...

In this paper we address the task of finding topically relevant email messages in public discussion lists. We make two important observations. First, email messages are not isolated, but are part of a larger online environment. This context, existing on different levels, can be incorporated into the retrieval model. We explore the use of thread, mailing list, and community content levels, by ex...

These spaces and experiences are appropriated and t...

With Enterprise Social Software (ESS) being increasingly used for internal communication and collaboration, an important question is how their success can be measured. In this paper we contribute to answering this question by investigating which methods and metrics organizations are currently applying for measuring ESS success. To do so, we have conducted 26 interviews with persons responsible ...

There is growing interest in understanding of how User-Generated Content (UGC) empowers online consumer behavior.

The results of this study reveal that Perceived Control has an influence on intention to use UGC. The findings also ...

Argumentation mining from social media content has attracted increasing attention. The task is both challenging and rewarding. The informal nature of user-generated content makes the task dauntingly difficult. 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...
