<br>Abstract:<br>
<br>
Text processing of social media data in NLP has largely centred around Twitter, with other social media types getting relatively little attention. In this talk, I will first present an empirical comparison of text sourced from a range of social media sites (microblogs, comments, user forums, blogs and Wikipedia), focusing on the relative "noisiness" and diversity of the linguistic content. I will then discuss the application of discourse parsing to user forum threads, and incorporation of the results to improve search quality.<br>
