Research On Ontology Construction And Reasoning Service Of Agricultural Science And Technology Information Resources Based On Semantics

With the rapid advance of agricultural informationization, a large number of agricultural science and technology information resource unordered accumulation. How to organize, manage and maintain agricultural science and technology information resources, more efficient and realize the sharing and reuse of agricultural science and technology information resource become the focus of the study, people of information resources sharing and reuse is the key to the sharing of information resources is a recognized and consistent understanding. Ontology is a kind of can effectively express the concept hierarchy and semantic relation model.It is considered to be knowledge organization, knowledge management domain the advanced method to solve the problem of information explosion. With a specific field of agricultural science and technology information resource service can be understood as: the combination of ontology is used to describe or expression of agricultural science and technology information resources concept or term and the relationship between the important to agricultural science and technology in the field of information entities, attributes, and their mutual relationship between formalization. Ontology for different platform provides a platform between information resources sharing and reuse.First of all, ontology technology applied in the field of agricultural science and technology, through the analysis on agricultural science and technology information field information resources in the field of relevant concepts and relationships between concepts described, ontology building agricultural science and technology information resources. Secondly provide related research reasoning technology, with the aid of reasoning machine and using the related reasoning rules, to effective inference of information resources, to expand the exhibition of semantic system, the design is based on agricultural science and technology information resource ontology semantic retrieval prototype system, using the system in the service of agricultural information, and then reach a higher level of the application of information resources. Specific work is as follows:(1) To build agricultural science and technology information resourcesontology. Combination of agricultural science and technology information classification standard, analyzes the concept and its hierarchical structure, the relationship between the use of protege ontology design tool, ontology building agricultural science and technology information resources.(2) Agricultural science and technology information resource ontology construction services research of reasoning. According to the general design principles of reasoning mechanism and strategy, and the purpose of reasoning design reasoning algorithm, with the aid of reasoning machine and inference rules, agricultural science and technology information resource ontology semantic reasoning framework.(3) Agricultural science and technology information resource semantic retrieval prototype system design and implementation. In the agricultural science and technology information resource ontology model and semantic reasoning mechanism on the basis of detailed research and function implementation, design services information retrieval prototype system.
