Using Lexical Acquisition to Enrich a Predicate Argument Reusable Database

Proceedings of the Sixth International Conference on Language Resources and Evaluation (LREC 2008)

Abstract

The work described in this paper aims to enrich the noun classifications of an existing database of lexical resources (de Matos and Ribeiro, 2004) adding missing information such as semantic relations. Relations are extracted from an annotated and manually corrected corpus. Semantic relations added to the database are retrieved from noun-appositive relations found in the corpus. The method uses clustering to generate labeled sets of words with hypernym relations between set label and set elements.
