Research Of Domain Intelligence Searching Engine Based On Ontology Techniques

The rapid development of Internet has brought the Internet users great convenience to access the information. The inflation of data with all forms, dispersed on numberless servers, make it difficult for users to find valuable information. The development of Search engine caters to the demand of the users in a way.The current Search engines develop towards domain and intelligence. The domain-based intelligent Search engine offers a safe and convenient way for the service of information within specific domain. Meantime, the research and development of domain-based intelligent search engine makes sense for the maintenance of national security and the enhancement of work efficiency.The ontology-based semantic web technology is the hot spot of the current research of domain-based intelligent Search engine and this paper mainly focus on analyzing and modeling parts. The introduction of the paper mainly talks about the background of current Search engine and illustrates its development, theory and constructer. Then it focuses on the domain-based intelligent search technique. The body part of the paper introduces the basic conceptions of domain, ontology and semantic web that are the bases of the domain-based intelligent Search engine. Then with the help of Protege and the combination of ontology, the paper introduces an ontology-based site information model. The final part of the paper carries the theory into execution which establishing a domain-based intelligent Search engine model based on ontology technique, followed with a verification of the final result on recall and precision.
