摘　　要：在现有的大规模的文献信息资源中发现知识与知识之间的关系,有利于新知识的发现,因此基于文献的知识发现成为很多学者关注的热点领域。而将文献资源的特点和主题显性地表示出来,则需要标引的支持。标引的质量与效率直接关系到知识发现的效果,由此可见标引是制约知识发现及其发展的瓶颈,同时也是知识发现的基础。本文首先对目前主要的基于文献的知识发现方法及其所涉及的资源标引的方法进行研究,从中发现标引对知识发现的制约因素,并提出相应的改进方向。Discovering the relationship among knowledge exist in numerous information resources will help the discovery of new knowledge.Thus,literature-based knowledge discovery became a hot area of research.Yet it needs indexing to show the features and themes of literature.And the quality and efficiency of indexing would affect the result of knowledge discovery.Therefore,the indexing would be a bottleneck of knowledge discovery as well as its basis.This paper studied the main methods of literature-based knowledge discovery and the related indexing methods,and found the constraints and problems.In the end,this paper discussed the improvement of these problems.
