Research
Our research currently revolves around the following topics:
- Argumentation Mining is the automatic search for arguments in text, and the automatic derivation of the argument's structure.
- Coreference Resolution seeks to determine which nominals in a text refer to the same entity. This includes figuring out what pronouns ("she" etc.) refer to.
- Probing the Climate Change Discourses is a set of student activities on using text mining methods on different text genres where CC is discussed.
- Discourse Structure and Discourse Parsing is the theoretical investigation of what makes a text "coherent", and the automatic analysis of such structures.
- Social Media processing deals with the peculiarities of automatically handling text from Twitter and other social media.
