The Reserach And Model Of Key Methods On Ontology-Based Education Resources Metadata System

Since the beginning of the new century, a lot of educational resources database began to appear in the network and more and more people start using the network to query the resources. With the increase in the number of network users, the knowledge of educational resources in network emerges in large numbers. Although the emergence of large amounts of information has played a positive role to help people in querying resources, but redundant information also add a lot of obstacles for people to accurately find useful knowledge. Ontology-based the educational metadata repository construction is a good program to solve the above problems. After the State Education Resource Metadata specification was issued, which helped processing the knowledge and skills of the ontology and metadata to educational resources in the network, in order to improve the users search accuracy.First, this article introduces on the standardization and development of educational resources in a number of domestic and foreign countries, and then introduces the basic theory of the theory of ontology and metadata, the article also describes on the emergence and development of the Semantic Web and the main seven-story structure; Second, introduces the core elements of the educational resources information technology standards. Then the Ontology-based educational resources metadata management platform module is designed. After that, use the seven-step method, the use of software in the field of educational resources ontology and to determine the contents of the object properties and data attributes. Finally, on the base of the front, makes the in-depth study of the inference mechanism of the main body and then cites the examples of reasoning.
