It is a process with long-term development and incessant extend and perfect for building well applied education resource element base. The point of improving resource employ efficiency is to add new element into element base with appropriate place. Directing against many classes and strong independency of education resource element, this paper studies the problem of classifying and merging field knowledge by conceptual clustering method, and implements dynamic conceptual clustering algorithm and merging algorithm,also analyses this kind of clustering algorithm in efficiency and clustering accuracy. 概念聚类 教育资源元素材 动态聚类算法 归并算法 conceptual clustering education resource element dynamic conceptual clustering algorithm merging algorithm G434 国家863计划资助项目（2002AA111010,2003AA001032） 2005-03-01 2021-04-01 3
