Abstract:

By analyzing the OWL Ontology storage medium and storage schema of the relational database, the flaws of various ontology storage modes are pointed out,a new ontology storage schema based on relational database is given. We use the ontology test frame of the education realm to test the storage schema finally.The experiments show that the new ontology storage schema of the relational database in this text has  higher searching efficiency and friendly expansion functions. It has more superior functions in each aspect than the perpendicular storage schema being used extensively now. It is also practical in saving largescale ontology.

Key words: OWL;RDF;ontology;storage
