As an important tool for knowledge reuse, knowledge sharing and modeling, ontology, especially domain ontology,plays an more and more important role in the information extraction system in recent years. The conception of ontology and the modeling criterion of ontology is introduced firstly. And then the ordinary existing modeling methods of ontology are analyzed. After comparatively analysing those kinds of modeling methods of ontology, a new modeling method of domain ontology is advanced according to the principle of information extraction and the concept of software engineering. It performs well in logic and operation and can be adopted in modeling certain domain ontology.%近几年来,本体作为一种知识重用、知识共享和建模的重要工具,尤其是领域本体,在信息抽取系统中扮演着越来越重要的角色.但是,目前领域本体的创建还缺乏系统的、工程化的方法.首先介绍了本体的概念及本体的建模准则,然后分析了现有的几种常见的本体建模方法,并通过对比分析各种方法的优缺点,再结合信息抽取的原理以及软件工程的思想,提出了一种新的领域本体的建模方法.该方法具有很强的逻辑性和可操作性,可被一些领域本体在建立时采用.
