General purpose word sense disambiguation methods for nouns in portuguese
Fernando Antônio Asevêdo Nóbrega, Thiago Alexandre Salgueiro Pardo · Lecture Notes in Artificial Intelligence · 2014
Word Sense Disambiguation (WSD) aims at determining the appropriate sense of a word in a particular context. Although it is a highly relevant task for Natural Language Processing, there are few works for Portuguese, which are tailored to specific applications, such as translation and information retrieval. In this work, we report our investigation of some general purpose WSD methods for nouns in Portuguese, tackling two additional challenges: using Princeton Wordnet (for English) as the sense repository and applying/customizing a WSD method for multi-document applications, which, to the best of our knowledge, has not been addressed before. In this paper, we also report our efforts on building a sense annotated corpus (for nouns, only), which was used for evaluating the investigated WSD methods.
