Abstract
In this paper, we propose a new scheme for modeling context life cycle in order to build smarter applications in ubiquitous computing environments. Existing context management system implicitly assumes that a context representing user’s situation can be fallen into just one of the two states such as valid or invalid. We observed that, however, a context can have additional state and transfer from one state to another seamlessly according to the change of a user-related context such as user’s location. The behavior of corresponding applications can also be finely tuned so that we can provide more adaptive services. For demonstration, we use the ontology for modeling and enriching the life cycle of a context. It enables us to utilize high-level inference capability which derives the current situation of a user. We also enhance the functionality of existing context management middleware using the context life cycle management scheme in this paper.
