摘　　要：以文本类型教学资源为研究对象,在领域知识可拓信息网模型和CELTS-3的基础上,阐述了基于信息元的教学资源组织系统设计与实现过程,包括信息特征元数据描述框架、特征词获取、信息元距离度量、信息元匹配规则以及匹配算法等。该系统通过有限的信息元描述无限的资源,实现了教学资源的高效组织,支持学习过程中资源自动重组。On the basis of extension information net of a field knowledge and CELTS-3, this paper targeted at text-typed teaching resources, and elaborated the process of design and implementation for teaching resources organizing system based on information units, including a describing basic data frame of information characteristic, obtainment of characteristic words, distance between information units, as well as matching rules and algorithm of information unit, etc. The system organizes infi- nite teaching resources by finite information units, implements efficient organization of the teaching resources, and thus supports the resources automatic regrouping in the process of learning.
