摘　　要：[目的/意义]科技文本资源是信息资源管理中的一种重要且普遍应用的知识资源,目前,在对科技文本资源进行组织的过程中,单一地采用粗粒度化的组织方法,缺乏丰富的语义信息,这不能满足用户精准化的知识需求。[方法/过程]以知识元理论为基础,通过对知识元进行抽取、标引、链接、集成,构建四层次六梯度的知识元映射,以期实现科技文本资源内容的有效关联与重组,并对其进行示例与讨论。[局限]科技文本资源组织效果的关键在于知识元抽取的质量。[ Purpose/significance ] Scientific text resource is a type of important and widely used knowledge resource in infor- mation resource management. At present, in the process of organizing the scientific text, the coarse-grained organization is still a- dopted as the only method, which is lack of rich semantic information, and cannot meet users＇ precise knowledge needs. [ Meth- od/process] Based on the theory of knowledge element, by extracting, indexing, linking, and integrating knowledge elements, the paper constructs the four-level and six-gradient knowledge element mapping in order to realize the effective correlation and reor- ganization of the contents of scientific text resource. And at the same time, the examples are explained and discussed. [ Limita- tions ] The key to the effect of scientific text resources organization is the quality of knowledge element extraction.
