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

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
