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.
