Abstract: According to the commonness and difference about some knowledge models, knowledge framework faced to field knowledge which expresses by XML is put forwards on the basis of ontology theory. Firstly, some definitions about ontology and knowledge modeling are presented, and analyzed the field knowledge. Therefore, from the different view of field knowledge pattern and field knowledge base, the different sub-knowledge frameworks are realized respectively. Then the whole framework about field knowledge is set up

Key words: Ontology; Knowledge model; Knowledge engineering; Knowledge management；XML; Domain knowledge

摘要： 基于面向领域知识表示模型的共性与差异，提出了一种基于本体的领域知识XML 表示框架模型。首先，给出了关于本体及知识建模的相关定义，并对领域知识进行了简单定义及分析；在此基础上，给出了面向领域知识的本体知识模型的XML 表示框架，对领域知识建模从领域模式和领域知识库两个方面进行了建模研究，实现了组成领域知识模型框架的两个子框架模型。
