    Abstract
    Develops a conceptual framework for information retrieval systems which admit of imprecision in the form of fuzziness in document characterization, retrieval rules, and file structures. A mathematical model for such systems, based on the theory of fuzzy sets, is introduced

    Abstract
    The authors analyse the specifics and results of lexical processing of scientific and technical texts for the purposes of information retrieval thesauri compilation and terminology unification. General and particular methods are identified for terms' meanings representation in thesauri and terminological systems. Procedures are proposed for concurrent solution of information retrieval tasks in descriptor systems and of terminology unification problems
