Context management in modeling information systems (IS)
Knowledge engineering methods are shown to have an important role in addressing the challenge of building trusted contexts; namely, in providing solutions to the problems of complexity, conformity, changeability and invisibility. Current information systems (IS) design practices, however, are seen to solve only those problems pertaining to the global enterprise system, while leaving the validation issues related to user/local models unresolved. Context management mechanisms associated with the user/local models are shown to provide a basis for dynamic validation of user requirements. The proposed context management process has been developed to allow context representation and dynamic knowledge structuring at the epistemological level.
