摘要
学科知识建模是一项复杂的工程,目前存在的问题主要有知识库不能很好地共享和重用,难以实现语义上的推理及检索。本体作为一种能够描述概念以及概念之间的关系、能在语义和知识层次上描述概念模型的工具,已应用于语义网、自然语言处理、资源共享和重用等领域,同时也受到学科知识建模者的青睐。以"数据库系统原理"课程的知识本体为例,详细阐述了课程知识元模型的构建、基于OWL DL的本体建模方法,最后给出了基于OWL DL设计的知识本体的部分代码,以供业内同行研究参考。
The discipline knowledge modeling is a complicated engineering.The major problems at present are that the knowledge base does not be shared and reused and hardly fulfilling inference and retrieval at the semantic level.As a description tool of conceptual models on describing concepts and relations among concepts on the semantic and knowledge levels,ontology has been applied to the areas such as the Semantic Web,Natural Language Processing,Resource Sharing and Reuse.At same time,it is also popular by model makers of the discipline knowledge.This paper takes the course＂Principles of Database Systems＂ as an example to introduce in detail a meta-model of the course knowledge and an OWL DL-based ontology modeling method for the course knowledge.Finally,a part of the OWL DLbased knowledge ontology is given as a reference for other researchers in this area.
