ONTOLOGY GENERATION PROGRAM, ONTOLOGY GENERATION DEVICE, AND ONTOLOGY GENERATION METHOD

摘要

An ontology generation device (1) uses a machine learning model generated by machine learning based on a knowledge graph to which an ontology (24) showing specific relationships between a plurality of words is added, and predicts other words having a specific relationship with a word included in the plurality of words. Then, the ontology generation device (1) adds the predicted other words to the ontology, thereby generating a new ontology (24). Thus, the ontology generation device (1) can generate the ontology with a rich vocabulary.
