Dissertation Project: Computational Analysis of Discourse Deixis

Discourse deixis refers to a type of reference in which certain expressions (e.g. this, that, it, etc.) are used to refer to discourse entities that are typically represented by verbal phrases and whole clauses or sentences, such as facts, propositions, or events. The variety of forms these expressions take renders them difficult to handle automatically, since many of the features commonly used for anaphora resolution are not available.

This project has as its goal a detailed quantitative investigation of the properties of discourse deixis as well as the construction of computational systems capable of processing such expressions adequately. I also plan to investigate to what degree interpreting these expressions can improve performance in other NLP tasks, such as automatic summarization or translation.
