| 摘 要： | 通过分析相关工作来揭示角色的基本特征，指出使用现有方法表示角色所遇到的困难和问题，指出角色间的约束超出了web本体描述语言OWL的表达能力．为了克服这些问题，提出了一个新的角色模型并提供了一种新的本体描述语言．该模型的核心思想是将角色看作是上下文的组成元素，并将上下文构造看作是由内部元素组成的结构化实体．由于上下文构造具有内在的模块化和局部语义性质，因此角色和上下文的表示非常自然和简单．

| Abstract: | The related work to reveal the primary characteristics of roles underlying the existing approaches is analyzed.Then,it is demonstrated that the representation of roles is rather complex and error-prone in these approaches.Especially,the constraints among roles in the same context cannot be expressed by the current web ontology language (OWL).To solve these problems,a novel model of role is presented and a corresponding ontology language is provided for representing this model.The key idea underlying the solution is that a role should be regarded as an element of a certain context and a context as a structured thing which is comprised of some internal elements.The structure of context possesses inherent modularity and local semantics,whereby the representation of roles and context is significantly simplified. |
