Abstract

In this paper, we present the preliminary results of a rule-based method for identifying and tagging elements in a hyponymy-hypernymy lexical relation for Spanish. As a starting point, we take into account the role that verbal patterns have in analytical definitions. Such patterns connect each term with its possible genus. We built a constraint grammar based on the results of a syntactic parser. The results demonstrate that constraint grammars provide an efficient mechanism for doing more precise analysis of syntactic structures following a regular pattern.
