教学构件的检索技术是教学构件技术的关键.笔者建立了教学构件的检索模型,构建了3层查询树和匹配树,提出了教学构件的4种匹配模型和3步综合检索方法,在此基础上设计了其匹配算法,为检索其他构件库中的构件提供了方法指导.

Retrieval technology of instruction component is the key of its technology.This paper builds a retrieval model of instruction component and three level retrieval tree and matching tree,presents four matching models and a method of three-step synthesis retrieval of instruction component,and designs a matching algorithm of instruction component at last.It provides a ...
