A Meta Data Model of Context Information for Dynamic Service Adaptation on User Centric Environment

Human can increase the conversational bandwidth using implicit situational and environmental information. But it is difficult to apply implicit information to current data model in order to enhance the communication ability between human and computer. In this paper, we are interested in data modeling of context information required to support dynamic service adaptation for increasing communication ability in user-centric environments. By improving the access capacity to context information for service adaptation, we can increase the richness of communication in human computer interactions and make it possible to produce more useful computational services. We are interested in the structure of meta-data model of context information required to support dynamic service adaptation in user-centric environments. Users want to get services anytime, anywhere and on any devices in various dynamic environments. The meta-data of context information is important for offering dynamic services and the reconfiguration context information for dynamic service adaptation. This paper designs a structure of meta-data model that supports the reconfiguration of the context for dynamic service adaptation. We classify the context information, as well as define its relationship with other context information on the basis of the application services, changes in the external environments.
