Abstract:

On the basis of studying the storage patterns of the OWL ontology and the existing storage patterns of ontology based on relational databases, this article proposes a new method of storing the OWL ontology based on relational databases. This method acts according to the structural word characteristics of OWL, designs a relation table to preserve the relations in the ontology between the resources, describes the features and constraints, depicts the l evels and equivalence relations of ontology, saves the semantic information of ontology well. The method is suitable for storing large-scale ontologies, and simultaneously enhances the efficiency of searching,inquiry and mapping.

Key words: relational database, OWL, ontology
