Domain Knowledge Base Constructing And Integrate Realization Based On Ontology

The domain knowledge base is a complex system and it involves to the multi- domains knowledge. Because of each domain has its own characteristic, and it has the appropriation concept, the attribute, the relations and so on, at the same time the discipline also exists overlapping and overlaps, therefore domain knowledge sharing and reusing is extremely essential. At present many scholars have established the different knowledge base system based on these knowledge, but these knowledge database systems are singleness and it is difficult to realize knowledge sharing and the exchange. This kind of situation make the application of domain knowledge systems which was built with great energy narrow and they cannot fully display the efficiency. The sharing and reusing system is not only to be possible to reduce the redundancy of the knowledge database and guarantees the knowledge database system succinct, but also may enhance the performance of the knowledge server. This paper adopts the strategy of establishment domain ontology, gives the explicit formalized description to the specific domain concept and terminology, and reduces or eliminates the confusion of concept and the terminology, in order to realizes the sharing in knowledge systems and strengthens the question solution ability of the system, realizes the interoperation in the knowledge system, and satisfies the user's request of system sharing and interoperation.This paper using Ontology to establish domain knowledge base, and taking the domain ontology of sweet orange plant disease as the example, proposing the knowledge concept system based on the sweet orange plant disease of ontology, has produced the sweet orange plant disease knowledge expression based on the ontology, and uses the ontology language -OWL which is recommended by W3C to implement. The establishment of this ontology may validly solve the problem of concept ambiguity and redundancy of sweet orange plant disease knowledge database, and may implement share and reuse. It enormously enhances the efficiency of the knowledge database system development. Through the establishment sweet orange plant disease domain ontology, This paper introduction agriculture information management domain with the ontology thought. It may promote the development of agriculture technology database and agricultural domain expert system.
