APPARATUS AND METHOD FOR MEASURING SIMILARITY BETWEEN ONTOLOGIES

摘要

PURPOSE: An apparatus and a method for measuring similarity between ontologies are provided to accurately measure similarity between ontologies in consideration of a concept included in ontologies and the structure of ontologies. CONSTITUTION: A path pair extracting unit(154) measures concept similarity to paths extracted from ontologies corresponding to paths extracted from an ontology. The path pair extracting unit extracts a path pair. A path pair similarity measuring unit(156) assigns a similarity weight value to the extracted path pair. The path pair similarity measuring unit measures the path pair similarity. A structure similarity measuring unit(158) measures structure similarity between ontologies using a sum value of the path pair similarity of the path pairs.
