摘要： 针对传统SWRL元模型难以表达规则前件中OWL类实例的问题，提出改进的元模型，采用逻辑运算符连接并区分规则的UML模型中不同的OWL属性和OWL类的实例。为规则设计了基于UML profile的建模机制。通过引入horn短句集、描述逻辑等知识表示方式，论证了用描述逻辑对部分基于UML建模的规则形式化的可行性，并给出基于描述逻辑对其形式化的方法。

Abstract: The traditional UML metamodel of SWRL is difficult to express individuals of OWL class in antecedents of rules. To solve this problem, this paper represents an improved metamodel, using boolean operator to connect and to distinguish OWL properties and individuals of different OWL classes in a UML model of rules. A method to model rules with UML profile is represented. For a part of rules modeled by UML, the feasibility of formalizing them into description logics is proved, and a technique to realize that is represented.
