An ontology as a medium of lexical meaning formal representation
The article examines the issue of lexical meaning formalization raised in computer science within the Se-mantic Web paradigm. An ontology is a logical theory that provides a formal account for lexical meanings of terms
in accordance with an underlying conceptualization. A lexical meaning of a term is conveyed by axioms of a theory written in a formal language developed for the purpose of ontology engineering, the term being considered as a formal language vocabulary unit. The accuracy of formal definitions depends on expressiveness of the formal language implemented for ontology development. The article discusses the basic syntactic rules of a highly expressive ontology language OWL2, and their use in formal definitions construction is instantiated by means of two formal definitions extracted from the ENVO ontology and the UBERON ontology.
