Research and Implementation of Patent Information Retrieval System Based on Domain Ontology
基于领域本体的专利信息检索系统研究与实现

Aiming at some problems in traditional information retrieval under the present network information environment, the paper puts forward patent information retrieval model based on domain Ontology, and makes in-depth study on the process and technical implementation of user retrieval request disposal, Ontology construction, Ontology visualization and semantic expansion, retrieval and storage. A prototype patent information retrieval system is also implemented. Via a series of retrieval effects tests, the model can ensure accuracy of information retrieval and greatly improve the comprehensiveness of information retrieval.
