摘    要:本体论是近些年来知识工程一个新的研究领域。为了有效地组织一种面向教育的知识服务系统———智能辅导系统中知识,本文试图把本体论应用于知识库的设计中,通过知识分层和分级,实现知识库的结构化,提高智能辅导系统的运行效率和问题求解能力。首先介绍了智能辅导系统的原理和结构,接着阐述了本体的理论基础:概念、构建元语、本体模型、构建原则,然后设计了“题目理解”本体、“题目求解”本体,用DAOK语言实现,从而使得知识库结构化和形式化。最后指出系统进一步需要完成的工作。

关 键 词:本体  本体知识库  知识分层和分类  DAOK

Abstract:Ontology has become a new research field in knowledge engineering in the recent years. In order to organize knowledge in an education- oriented knowledge service system,an intelligent tutoring system, this paper applies ontology into the design of knowledge base, and through the hierarachy and classification of knowl- edge, and the structuring of knowledge base, to improve the efficiency and problem- solving ability in this system. Firstly, the principle and structure of an intelligent tutoring system is introduced. Next, the basic theory of ontology, including conceptions, modeling primitives modeling and principles of modeling of ontology is discussed. Then, the ontologies of problem - understanding and problem - solving are designed and implemented in DAOK, so as to make knowledge structural and formal. Fianally, luther reasearch work is to be done next is proposed.
Keywords:DAOK
