Abstract: When extracting key concepts and relations in traditionally ontology creating, it adds the cost of creating an ontology and restricts the development and population of semantic Web if specialists from several fields take part in. To solve the problem, this paper analyzes the differences between UML class diagram and OWL, proposes the method of mapping the fields knowledge extracted from UML model such as concepts, attributes, relations and restricts of the ontology to OWL ontology, and illustrates the OWL ontology mapping based on UML class diagram to realize convenience and efficiency of ontology creating.

摘要： 传统的本体构建在抽取关键观念和关系时，各领域专家的参与增加了构建领域本体的成本，限制了以领域本体为基础的语义网的发展和普及。针对该问题，通过分析UML类图和OWL的异同点，提出从现有UML模型中提取本体的概念、属性、关系、约束等领域知识并将其映射为OWL本体的方法，利用该方法将加油卡发行UML模型成功转换为OWL本体，从而实现本体创建的经济性和高效性。
