An Ontology-based Approach for Context Modeling in Collaborative Services

With the acceleration of globalization and regional economic integration, resources and markets need to connect effectively in a wider scope. Current information technologies provide capabilities for sharing information and linking resources across enterprise boundaries. The enormous amount of sensor data created during the process execution compose the context for current collaborative processes. For improving the coordination of collaborative services responding to context update, this paper proposes an approach for collaborative services in the perspective of context modeling. We analyze the context life cycle how context data move from phase to phase. The context life cycle consists of five phases: a) context acquisition, b) context handling and storage, c) context modeling, d) context reasoning and e) context distribution. In addition, ontologies of general collaborative network with context involved are presented in this paper, which include collaborative organizations, business processes and context information. More specifically, context entity consists of user context, activity context and environment context.
