Abstract

Abstract: Ontology is defined as an explicit formal specification of a shared conceptualization. It can provide semantic meaning through relations between concepts. As a fine model for presenting hierarchy and semantic meaning of concepts, Ontology is widely concerned and extensively applied to many fields in computer science and technology. With regard to little research on ontology in China, The state of the art of ontology is surveyed in this paper. This work first analyzes connotation and methodology of ontology, and then analyzes its applications in information system in details. The paper ends with a short conclusion and future work.

Key words: Ontology, information system, semantic Web, XML, RDF

摘要： Ontology是描述概念及概念之间关系的概念模型，通过概念之间的关系来描述概念的语义。作为一种有效表现概念层次结构和语义的模型，Ontology被广泛地应用到计算机科学的众多领域。本文作者对目前Ontology的研究与应用现状进行了综述性地介绍，从Ontology的定义Ontology理论研究、Ontology在信息系统中的应用以及在语义Web中的地位等方面加以了系统阐述。

关键词: Ontology, 信息系统, 语义Web, XML, RDF
