摘要：AbstractThe report is devoted to the use of methods of cognitive analysis for identification of relations between term semantics and conceptual structures of expert knowledge storage. Conceptual educations, cognitive formats of storage of expert knowledge and language cognition in their interaction are considered in the article as causing formation of terminological nominative units.The authors analyze mechanisms and tendencies that are characteristic of different categories representation and consider the distinctive relationship between categories representation and the use of productive term elements that in some cases leads to the establishment of explicit term oppositions. Some regularities in different terminologies related to the issue are discussed. We also examine possible reasons that govern the choice of word to serve as a term element that is relevant for a particular category.
