Abstract

This paper describes the implementation of a grammar fragment of Brazilian Portuguese (BP) in the Lexical-Functional Grammar (LFG) formalism using the XLE system. This fragment analyses, among other phenomena, verbal and nominal agreement, adjective syntax, passive, verbal valence, complement clauses, prepositional phrases functioning as adjuncts, grade adverbs and control verbs. For the evaluation of this grammar, a parser was compiled in XLE and applied to a positive and a negative test set. The former contains 72 grammatical sentences, all of which were correctly analyzed. The latter contains 88 non-grammatical sentences, of which none were analyzed.
