Abstract:

Along with the increase of ontology types and resources, the structure of ontology is more and more complicated. In order to store various structure types of ontology properly to support efficient ontology queries, this paper puts forward an ontology storage method based on relational databases, which uses a word formation classification method different from the traditional decomposition to store different types of OWL features in twodimensional tables to solve the complex relationship between the resources and the attribute values, and ensures the integrity of the semantic information. Then, it uses the efficient retrieval and matching speed of relational database management systems, and the SQL language’s high degree of deproceduring to retrieve and matching OWL ontology into a relational database, thus compensates for the defect of low efficiency of the query OWL ontology.
