Lexical Meaning Formal Representations Enhancing Lexicons and Associated Ontologies

The paper represents an outline of a new technique aimed at improvement of lexicon-to-ontology mapping technology. The technique is integrated within the Ontolex-Lemon lexicon model by supplying a lexical concept of an ontology class with a description logic based formal definition. A natural language definition used to describe the lexical concept is transformed into a DL-definition; the resulting DL-definition is associated with a graph-like join of domain ontology properties. As a result, a related lexical unit is mapped to several bound ontology units rather than to a single ontology class. DL-based and graph-based lexical meaning formal representations are applied for lexical sense disambiguation within a lexicon and for extension of class and property taxonomies of an associated ontology.
