Nominal Semantic Role Labeling

asd

Overview

Across the internet, a significant amount of information resides in non-spoken, unstructured language repositories such as news articles, Wikipedia, and weblogs. The goal of semantic role labeling is to uncover the basic semantic structure of these texts by identifying events and event participants. Traditional research in this area has focused on events denoted by verbal predicates. Furthermore, the scope of participant identification has usually been restricted to the sentence containing the predicate of interest. This project extends traditional semantic role labeling in two important ways. First, it investigates semantic role labeling for nominal (i.e., noun-based) predicates, which are prominent carriers of semantic information. Second, it relaxes the scope of participant identification to include all sentences in a textual discourse. Together, these two extensions provide a more complete account of textual meaning and discourse coherence.
