Abstract:

SummaryMost of lexical ambiguity caused by homography can only be resolved by the syntactic analysis of the structures where the homographs appear. Thus, in order to resolve ambiguity caused by the homography between nouns and adjectives, we constructed for Portuguese formal grammars that describe noun phrase structures with adjectives. The formal properties of about 2,000 adjectives have been studied and, according to their behavior, they have been integrated in different classes and sub-classes. The syntactic and distributional properties of those adjectives were coded and associated to the corresponding entries of the Portuguese electronic dictionary DELAS. Furthermore, a library of more than one hundred local grammars for resolving ambiguity was constructed. Those grammars are represented internally by finite transducers that, in combination with the dictionary information, are applied by INTEX to the disambiguation of noun phrases. Some results of disambiguation are briefly discussed and exemplified.
