Abstract

The new techniques of domain analysis (thematic, etc.) supply methods to create repositories or sets of structured information. A specific methodology to automatically generate domains (thematic, etc.) uses as repository a structure based on documental thesauri. One of the stages described in this methodology to generate a thesaurus is the acquisition of concepts using statistical techniques to filter information. This paper presents modifications to these filtering techniques to obtain composite terms.
