Mathematical Model of Information Retrieval System Based on the Concept of Fuzzy Thesaurus

Radecki, Tadeusz

Information Processing and Management, 12, 5, 313-18, 76

The application of the theory of fuzzy sets to the description of information retrieval systems makes it possible (1) to take into account the fact that the degree of importance of the particular terms is of a continuous character, (2) to formalize the relations between terms describing documents and information requests (fuzzy thesaurus).
