Construção automática de um thesaurus retangular.

Abstract

The researches in the field of Textual Databases indicate that the thesaurus is a very useful tool for indexing and retrieving textual information. In the great majority of Textual Databases, the thesaurus construction is not done in a automatic way. This work presents a system for the automatic construction of a thesaurus. This work is based on two other researches. The first research is concerned with the initial steps for building a thesaurus: the extraction of terms from a set of documents. The second research deals with the process of organizing the terms and the document using a conceptual model. The unification of these two researches led to the implementation of a system used for the automatic construction of thesaurus.
