本文以本体思想作为理论指导，将狭义的学科知识结构理解为学科知识点的层次体系，进而借助本体学习技术从CSSCI期刊论文集合中衍生出CLIS的学科知识结构，并对其在2003—2010年10年间的发展轨迹进行了初步探测。

英文摘要：

Taking the idea of ontology as a theoretical guidance, this paper interprets the disciplinary knowledge structure in narrow sense as a hierarchical system of disciplinary knowledge points. Then the disciplinary knowledge struetare of CLIS is derived from CSSCI papers with the help of ontology learning technology, and its development track over ten years （2003 -2010） is detected. The specific process includes the building of keywords-scholars matrix based on filtering for hot keywords and core authors in CLIS, the generation of CLIS knowledge structure based on multi-level k- means clustering, ontology description and visual display for CLIS knowledge structure based on OWL, the checking for cohesion and coupling of knowledge categories based on hierarchical clustering and multidimensional scaling analysis, and the analysis for development track of CLIS knowledge categories based on knowledge mapping on different granularity levels. After verification, the knowledge system of CLIS constructed in this paper has a certain rationality and effectiveness, and it could lay the foundation for the latter study on broad knowledge structure of this discipline.
