Abstract: According to the ideas of knowledge management, a knowledge warehouse scheme based on knowledge context, knowledge content and knowledge outline is proposed in this paper. And knowledge warehouse schemes in KMS are designed in detail by using knowledge modeling language CML. Moreover, five matching schemes for retrieving knowledge based on knowledge context tree are classified. Finally, the relations between precision and matching scheme are explored

摘要： 根据知识管理的思想，提出了一个基于知识背景、知识内容和知识外形的知识仓库模式，并利用知识建模语言CML 对该知识仓库模式进行详细设计。针对知识背景是树结构的情形，结合树匹配的思想，设计5 种知识检索匹配类型，讨论了匹配类型与知识查准率之间的关系。
