RAP - a basic context awareness model

This paper addresses two fundamental research problems in the domain of context sensitive systems: the development of a generic context model that can be used to represent general purpose contexts in a computer interpretable way and the context model management. The context model is represented using a triple set consisting of context resources, actors and policies. The model is mapped onto real contexts by populating the sets with context specific elements. A context situation to which a context aware system must adapt is represented by a specific context model instance. To ease the context reasoning and adaptation processes, a core ontology is defined to represent the relationships between the context model concepts. The core ontology is extended with domain specific concepts as ontology sub-trees. For the context model management problem we propose an agent based solution using BDI agents.
