| 摘 要： | 在领域本体的基础上，对面向专利文献的语义检索与分析方法进行探讨，并构建一套专利语义检索与分析系统，包括语义检索、趋势分析、相似专利检测、重要专利检测等模块，初步实现基于领域本体的专利语义检索与挖掘。同时，以国际专利分类号为C21的中文专利数据为例进行实验，证明本体扩展后的语义检索的召回率得到大幅提高，继而使得后续的专利分析和挖掘效果更加明显，从而有助于进一步深入开展专利挖掘工作。

| Abstract: | As most of the latest technology methods were revealed in patent documentations, enterprise information departments have to deal with a key issue which is how to make good use of patent documentations. This paper has built a semantic retrieval & analysis system on the basis of domain ontology. This system contains such modules as semantic retrieval, trend analysis, similar patents detection, and important patents detection. With this system, domain ontology-based patent semantic retrieval and patent mining can be achieved. In addition, tests have been carried out on the Chinese patents classified as C21 in the IPC system. It has been proved that the recall ratio of semantic retrieval is greatly improved after ontology expansion, which in turn makes the subsequent patent analysis and mining more effective, and thus contributes to the further implementation of patent mining. |
