Abstract

This paper presents a variant of Lappin and Leass’ Algorithm for pronoun resolution in Portuguese texts; the algorithm resolves third person pronominal anaphora, as well as reflexive and reciprocal pronouns. It relies on salience measures, derived from the syntactic structure of the sentence, and on a simple discourse representation model. The algorithm, as well as its evaluation with legal and literary corpora, are presented.
