Abstract

The paper describes the structure and properties of a large linguistic ontology – a new kind of information retrieval thesaurus - Thesaurus on Sociopolitical Life for Conceptual Indexing. The thesaurus is used in various real-scale information-retrieval applications in the legal domain. At present one of the main applications of the Thesaurus is knowledge-based text categorization. Categories are connected with the Thesaurus by flexible relationships. The categorization system can process text collections containing texts different in sizes and types.
