摘要
本体作为一种能在语义和知识层次上描述信息系统的概念模型建模工具,近年来在计算机的许多领域得到了广泛的应用。其中,基于本体的知识构建是一个复杂的系统工程。就目前的研究状况来说,主要是解决如何构建知识模型的问题。本文运用本体知识模型相关的理论,在分析了本体论、知识库和知识库系统概念的基础上探讨了本体论在知识库系统中的应用和方法,提出了一种基于本体的知识模型,并阐述了基于本体的知识库构建方法。
As a modeling tool in describing the concept model of information systems in at the semantic and knowledge level, ontology is widely used in many areas of computer science in recent years. Among which the ontology-based knowledge construction is a complex project, according to the current research situation,and the key is to resolve the problems of how to build a knowledge model. This paper takes advantage of some theories related to the ontology knowledge model. Based on the analysis of ontology, we discuss the application and the method of ontology in knowledge-based systems. Finally we propose an ontology-based knowledge model, and explain the method of ontology-based knowledge base construction.
