[Abstract]:With the rapid progress of agricultural informatization, a large number of agricultural science and technology information resources are stacked disorderly. How to organize, manage and maintain agricultural science and technology information resources, and to realize the effective sharing and reuse of agricultural science and technology information resources has become the focus of research. The key is to have a recognized and consistent understanding of the information resources shared by agricultural science and technology information resources. Ontology is a model that can effectively express the relationship between conceptual hierarchy and concept semantics. It is considered to be an advanced method to solve the problem of information explosion in the field of knowledge organization and management. Combined with the specific field of agricultural science and technology information resources service, it can be understood as: ontology is used to describe or express the concepts or terms of agricultural science and technology information resources and their relationships, to the important entities in the field of agricultural science and technology information. Ontology provides a platform for sharing and reusing agricultural science and technology information resources among different platforms. Firstly, the ontology-related technology is applied to the field of agricultural science and technology. Through the analysis of the information resources in the field of agricultural science and technology, the relationship between the related concepts and concepts is described, and the ontology of agricultural science and technology information resources is constructed. Secondly, the related research of reasoning technology is carried out, the information resources are inferred effectively, the semantic system is expanded and the prototype system of semantic retrieval based on the ontology of agricultural science and technology information resources is designed, and the information serving for agriculture is obtained by the system. And then achieve a higher level of application of information resources. The concrete work is as follows: 1) constructing the ontology database of agricultural science and technology information resources. Combined with the classification standard of agricultural science and technology information, this paper analyzes the relationship between its concept and its hierarchical structure, and uses prot 茅 g 茅 ontology design tool to construct agricultural science and technology information resource ontology reasoning based on OWL description. On the basis of the ontology of agricultural science and technology information resources, the design and implementation of the prototype system of semantic retrieval of agricultural science and technology information resources is put forward with the help of Jena inference engine and inference rules, and the semantic reasoning framework of agricultural science and technology information resources. Based on the detailed study of ontology modeling and semantic reasoning mechanism of agricultural science and technology information resources, a prototype system of semantic retrieval is designed.
