Two corpus based experiments with the Portuguese and English Wordnets

Abstract

This paper presents two experiments with real world applications of word sense disambiguation, wordnets and dependency parsing. The first is an effort towards a Portuguese wordnet annotated corpus.We manually annotated 30 sentences using Open Word Net-PT as a lexicon and then compared the results with an automatic annotation. In addition to the system's evaluation, the results provided valuable insights about how to deal with such an ambitious task. The second experiment deals with using Princeton Wordnet as part of an NLP pipeline for information extraction from technical texts in the mining domain and the issues found while integrating word sense disambiguation with a syntactic analysis of the sentences.
