Processing of the Natural Language for Information retrieval

Introduction

    In the last international congress on Semantic Web the presence of applications centered in Processing of Lenguaje Natural (PLN) was more than remarkable, in fact, Gate, a well-known application for designed linguistic engineering in the university of Sheffield, was one of stars invited when referenced appearing in a good number of the works presented/displayed to the congress.

    However, the utility of the natural processing of the language for the implementation of a Semantic Web, is not a discovery of this year. In the past 2004, Ricardo Baeza-Yacht I sign an interesting work on the application of techniques of processing of the natural language for the Information retrieval where it proposed to the Semantic Web like one of the main practical applications of convinadas techniques of PLN (processing of the natural language) and RI (information retrieval).

    Many can argue that the own father of the idea defends that the Semantic Web is not a Web based on techniques pertaining to the area of Inteligencia Artificial (IA), but this does not mean that we did not prune to use these techniques as bases and support for the implementation of its idea, since, beyond quarrels of academic character, everything what it helps us to make reality a new Web is useful independently of conceptualizaciones of
theoretical character.

    It is necessary to consider that, at the present time the Semantic Web does not exist like so, beyond precise implementations of experimental character. The fact that it exists inexorably passes through the generation of semantic contents Web that give body to the idea of one more an organized Web. The generation of contents of semantic character is not assimilable of manual form by the users and authors of the Web, reason why the automatization of all is necessary, or at least part of the tasks of generation of semantic contents Web. It is here where
the PLN and the RI have much to contribute, since they allow the implementation of applications able to generate information of semantic type that dowry of body to the Semantic Web and turns it a reality.

    Parsers, who allow to include/understand the structure of the phrases of automatic form, lexical, reconocedores etiquetadores of organizations like names, dates places, all of them are essential automatic tools for the generation of semantic contents Web, is more, I dare to say that without them it is not possible real a Semantic Web, since the cost of manual elaboration of semantic contents is not assimilable from any point of view.
