中文摘要：

[目的／意义]从细粒度角度深化科技文本的内容语义描述，弥补目前文本知识对象特征描述粒度较粗且缺乏语义的不足，为知识重组与挖掘，提供精细化的用户知识服务给予一种思路。[方法／过程]以知识元理论为基础，通过对科技文本内部属性的语义分析，尝试构建细粒度的科技文本内容描述框架，给出两个实例并讨论。[结果／结论]该内容描述框架实现了检索结果从海量的文献单元聚焦到精准化的知识元的转变。

英文摘要：

[ Purpose/significance] We attempt to deepen the content semantics description of scientific text from the fine-grained perspective, make up the deficiencies which text knowledge object characterization is coarse and lack of se- mantic currently, andgive a way of thinking for knowledge reorganization, mining and refinement of the user knowledge service. [ Method/process] Based on the knowledge element theory and the semantic analysis of the internal attributes of the scientific text, we attempted to construct a fine-grained content description framework of scientific text knowledge ob- ject and give two examples and discussion.[ Result/conclusion ]The content description framework realizes the transfor- mation of the search results from the massive document unit to the precise knowledge element.
