Mining e-services in P2P-based workflow enactments

This paper aims to explore the feasible mining and proper selection of QoS-aware services for a P2P-based business process enactment framework, and enhance the relevant workflow prototype. Through observing and analysing unpredictable dynamic changes which commonly exist in e-service workflow, we propose a set of QoS specifications and monitoring mechanisms in a P2P workflow framework. These specifications are an evolving extension of services’ description with semantic Web facilitators for P2P-based e-services. It has been demonstrated that our QoS-OWL approach can be effectively used to describe and exploit e-services, particularly in decentralised environment. QoS-OWL is also able to provide the deliberation of geographic information for e-services, and facilitates the peers' effective cooperation and automates business processes. It is recommended the approach be adopted in the dynamic online information system environment to increase efficiency and reduce costs in running e-services.
