摘要
领域本体提供了丰富的概念集,是领域知识共享的基础。讨论了电子教学系统中课程知识体系的组织与本体表示方法,构造了基于领域本体的知识发现模型,阐述了基于领域概念对相似性的本体映射过程,实现了基于单元知识的电子教学资源的灵活共享。
Domain ontology provides a rich set of concepts for shared knowledge,and it is the base of sharing domain knowledge.This paper discusses the methods of organization and ontology representation of the curriculum knowledge system,constructs the knowledge discovery models based on domain ontology,expounds the mapping process between two ontology based on the similarity of domain concept couples.h realizes the flexible share of teaching resource based on the unit of knowledge.
