Course description

The workshop aims at bringing together research in two complementary fields of semantic analysis that are still too far apart. In order to achieve both a broad and a deep understanding of any given text document, a system needs both advanced acquisition of corpus specific lexical semantic knowledge and powerful inference mechanisms that utilize that knowledge in discourse analysis.

Given the still relatively limited results within both areas there has been little impetus to combine them. Corpus-based extraction of lexical semantic knowledge has only recently become a more feasible task, because of the growing availibility of on-line text documents and robust corpus processing technologies. Simultaneously, the various approaches to discourse analysis are in the process of converging into a unified approach to the analysis and representation of the cohesive structure of natural language documents.

The intersection between these two fields lies in the application of lexical semantic knowledge to such problems in discourse analysis as anaphora resolution and discourse segmentation. In fact, the benefit will be mutual, because knowledge of discourse structure is helpful to lexical knowledge extraction as well.
