Pervasive computing systems that strive to be minimally intrusive and exhibit inherent proactiveness and dynamic adaptability to the user preferences and environment need to be context-aware. Contextawareness provides computing environments with the ability to adapt the services or content they provide, by implicitly sensing and automatically deriving the users? needs from the context that surrounds them, making services more attentive, responsive and predictive. This paper is concerned with the development of an ambient context management system that aims to maximize the automation of the complete context knowledge lifecycle via the establishment of a flexible prototype context ontology.
