Lots context information needs to be exchanged. The context information represents in different way from different resources. Make the context-aware system consuming lot efforts to deal with the different context information representation ways. This thesis uses ontology specifies the expression of context information and proposes context-sharing platform architecture. The platform was designed as multi-agent distributed system. The platform can be divided into three parts: sensing agent, service agent and context server. The sensing agents collect the information provided by sensors or external resources. The service agents provide services and create new knowledge by the contexts provided by the context servers. The context servers collect the information provided by the sensing agents and the he service agents. Also separate a Sensing Ontology base on CONON hierarchical structure. Sensing Ontology can be merged into other ontologies for different domain. A dynamic ontology mechanism is proposed by such an ontological structure. Make the diversity of the description ontology in the context servers can be gained.
