Establishment of computational framework of role concepts contributes effectively to management of instance models because it provides us with a useful policy for treatment of views and contexts related to roles. In our research, we have developed an ontology building environment, which provides a framework for representation of role concepts and their characteristics. In this paper, as an extension of this framework, we present a framework for organizing role concepts according to their context dependencies. We especially focus on defining and organizing a role concept which depends on several contexts.
