专利信息检索技术

Research on patent information retrieval technology

专利信息检索作为快速获取专利信息的主要手段,在专利信息应用过程中发挥重要作用。本文在分析当前专利信息检索涉及的关键技术的基础上,进一步阐述了基于概念的专利信息检索技术。本文以对专利文献的内容分析为基础,按照文献中各部分的功能进行组织表示,对不同部分制定相应的特征选择策略。同时,对基于概念的专利信息检索技术中的两个关键问题即查询扩展和专利文献相似度计算方法进行了阐述。

Patent information retrieval is a major means to access the patent information,it plays an important role in the patent application.Base on the analysis of current technologies involved in patent information retrieval,we propose a patent information retrieval approach on the concept.First,we analyze the concept content of patent documents,and according to this,use different feature selection method.Then,the key issues of the concept-based patent information retrieval method including query expansion and patent similarity calculation are also described.
