Abstract

Web service selection is a key issue in the service-oriented computing. Generally, Web services are provided with different QoS values, so they can be selected dynamically in service composition process. However, the conventional context free QoS selection model does not consider the context sensitive constraints and the changeability of QoS values. This paper proposes a policy-based context sensitive QoS model to effectively calculate QoS values and select web services. By introducing context to the QoS model, web service composition can be used widely and flexibly in the real world business.
