METHOD FOR QUERY TRANSLATION TO RESOLVE VOCABULARY-GAP IN ONTOLOGY QUERYING

摘要

PURPOSE: A query language conversion method is provided to enable a user to find desired information by converting user query language into an ontology title language. CONSTITUTION: A conversion target query language is extracted from the search query languages(S10). The query language is extended using a thesaurus except for the query language which is matched with an ontology resource name (S40). A meaning tree converts the query language matched with the ontology resource name from the extended thesauruses. A query language unmatched with the ontology resource name is created using a language meaning system dictionary(S70). Words for displaying the ontology resources are extracted from ontology.
