Thesaurus modelling of the semantic field of the term ''word'' in the subject field «English lexicology»

Based on principles of semiotics and linguistic synergetics, the article deals with the peculiarities of thesaurus modelling of the semantic field of the term ' word', which stands to be the key one entering the semantic domain 'general lexicological terms' ', which, in its turn, enters the semantic space of the subject field «English lexicology». The componential analysis of corpus of English-language definitions of lexicological terms has revealed implicit semantic features of terminological signs (TS) and terminological word-combinations (TWC) with further description of the semantic relations linking these units by «rigid» frameworks of a dictionary entry. According to the results of the linguistic experiment based upon the Neo-Saussurean theory of the terminological sign there have been defined equivalent, hierarchical and associative relations between the head term ' word' and other terminological units within the modelled semantic field.
