摘要
针对科研工作中的“问题”和“方法”，分析知识查询需求，提出了论文的“研究问题”和“技术方法”的概念结构。分析了两类概念结构对应的语言描述结构——短语结构。设计了支持两类概念理解的概念网络，以及一系列概念运算的算法，提高了查询短语和论文知识描述的匹配度计算精度。
According to the demands of analysing knowledge inquiry about＂questions＂ and ＂methods＂ in the scientific research work, the concept structure about ＂the research question＂ and ＂the technical method＂ in a paper is proposed.Two phrase structures, namely language description structure in correspondance with two genus structures namely have been analyzed, And also the concept network that is supporting the understanding of two genus has been designed, as well as a series of concept operation algorithm, hence the match computation precision between the inquiry phrase and the paper knowledge description is enhanced.
