AN EFFICIENT SYNTACTIC ANALYZER FOR SPANISH GRAMMARS

Abstract

The research that is presented in this article is developed in the Computational Linguistics Area, specifically in the syntactic parsing processing for the treatment of the Spanish language. Basically, the development and implementation of an efficient syntactic parser is described, which utilizes a prototype of computational grammar for the Spanish. The base of the system is the Left-corner algorithm; and additionally, the Unification Formalism for Definite Clause Grammar (DCG) that the system utilizes has been defined. The efficiency of the parser owes mainly to the implementation of the algorithm for unification grammars, and to the creation of the module where the compilation of the rules is carried out. The process of the syntactic parsing has been achieved with sentences that have been taken from the corpus of the project MULTEXT, those sentences contain an extensive variety of the Spanish syntactic structures. Finally, the evaluation of the system is argued from the obtained results, and future jobs are projected for developing.
