A Study On Relational Database-based Ontology Storage

Ontology can describe the concept as a modeling tool on semantic and knowledge level, also can solve the key problems of the information sharing and reuse effectively in the information domain. Ontology has already become the research focus of the artificial intelligence domain in recent years, its'main research contents include Ontology expression, Ontology structure, Ontology integration and Ontology storage etc.In order to reuse and share the information in the information domain, Ontology which structured to the information system domain needs to be store. This paper introduces Relational Database technology to Ontology storage and studies the method which stores Ontology directly to the Relational Database, this method produces a new storage mode, and the mode stores the regular Ontology enquiry information to different tables according to the characteristic of ontology description language. The whole mode is apt to understand, the structure is steady, and it reduces the cost of tables'connection in Ontology enquiry, also improves the enquiry efficiency.The key technology includes: structure method in domain Ontology, the Ontology storage and the storage technology research based on relational database. This paper structures document Ontology of marine discipline, studies Ontology storage facing the information domain, the storage way is simple and flexible, can offer semantic guidance to users, has strong reasoning ability, and analyzes a series of storage strategy. The experimental result indicates that this storage method not only have high enquiry efficiency but also have good expansibility, it is suitable for storing extensive Ontology.
