Un módulo de desambigüación morfosintáctica para el castellano basado en conocimiento lingüístico

In this paper we describe a computational tool for morphological disambiguation for the Spanish language, designed to be eventually part of a larger grammar checking system for both Spanish and Catalan. This system is based on two different types of tools, namely, a) a low-level morphological parser, and b) a high-level syntactic-semantic parser. At present, we are developing all low-level tools, which, in the mid term, should constitute the basis for a grammar-checking module capable of capturing simple errors in unrestricted text. The rule file contains some 743 rules for morphological ambiguity, which are applied 130.751 times over our development corpus.
