Ontology generation system, ontology generation method, and computer readable medium

An ontology generation method comprising:

• computing a similarity degree between each of one or more partial ontologies in a first-system-oriented ontology and a benchmark ontology of a second system, as a similarity degree of each of the partial ontologies;
• extracting as an ontology candidate from the first-system-oriented ontology, a set of:
• each of partial ontologies having similarity degrees which satisfy a similarity degree condition;
• and a partial ontology for linking to each other the partial ontologies having the similarity degrees which satisfy the similarity degree condition;
• determining whether or not the ontology candidate satisfies a constraint condition;
• and
• outputting, when the ontology candidate satisfies the constraint condition, the ontology candidate as a second-system-oriented ontology.

A non-transitory computer readable medium storing an ontology generation program which causes a computer to execute:

• a similarity degree computation process of computing a similarity degree between each of one or more partial ontologies in a first-system-oriented ontology and a benchmark ontology of a second system, as a similarity degree of each of the partial ontologies;
• a candidate extraction process of extracting as an ontology candidate from the first-system-oriented ontology, a set of:
• each of partial ontologies having similarity degrees which satisfy a similarity degree condition;
• and a partial ontology for linking to each other the partial ontologies having the similarity degrees which satisfy the similarity degree condition;
• a constraint determination process of determining whether or not the ontology candidate satisfies a constraint condition;
• and
• an ontology output process of outputting, when the ontology candidate satisfies the constraint condition, the ontology candidate as a second-system-oriented ontology.
