知识工程中的知识库、本体与专家系统

摘要

随着语义Web思想的兴起,对专家系统的互操作性和共享性也提出了更高的要求,对新型知识表示方式和新型知识系统的研究是大势所趋.本体作为共享概念模型的明确的形式化规范说明,为不同系统之间的互操作提供了基本的框架,是解决共享和互操作问题的有效的方法.一些初学者对知识库、本体以及专家系统的概念产生了各种疑惑,根据笔者的理解与实践,对知识工程中的本体、知识库以及专家系统做出较系统的比较分析,对这几个术语做一个澄清.%With the development of the Semantic Web, the interoperability and sharing of expert system were put forward more advanced requests. The researches for new knowledge representation and knowledge base systems are important trend. As a formal, explicit specification of a shared conceptualization, ontologies provide frames for interoperability between different systems and can solve the sharing and interoperability problem effectively. There were a variety of doubts in some beginners' mind with the concepts of knowledge base, ontology and expert system. Based on the author's understanding and practice, the systematic comparative analysis between knowledge base, ontology and expert system in the domain of knowledge engineering were proposed in this paper, in order to make these terms less confused and more clearly comprehensible.
