针对传统信息检索方法在当今网络信息环境下所面临的问题,提出基于领域本体的专利信息检索模型,从用户检索请求处理、本体构建、本体可视化与语义扩展、检索及存储的过程和技术实现进行研究,并开发一个基于服装领域本体的专利信息检索原型系统。比较测试表明,该模型在确保信息检索准确性的同时能够极大地提高其全面性。 Aiming at the problems that the traditional information retrieval methods face in today’s network information environment, a patent information retrieval model based on domain ontology is proposed, which is based on the process and technology implementation of user retrieval request processing, ontology construction, ontology visualization and semantic extension, retrieval and storage Research and develop a prototype system of patent information retrieval based on ontology of clothing field. Comparative tests show that the model can greatly improve its comprehensiveness while ensuring the accuracy of information retrieval.
