Abstract

QoS driven service selection as an important way to satisfy user's constraint on quality and maintain the runtime performance of services, has received much attention. This paper proposes a method for evaluating the QoS trustworthiness which reflects the possibility that the service can perform as its estimated QoS. Besides this, trustworthiness QoS driven service selection is also proposed. The experiments shows the proposed approach can reflect the dependent relation between estimated QoS and the environmental context effectively, and can insure the accuracy of trustworthiness evaluation. Meantime, the proposed service selection approach can improve the actual runtime performance of the selected service.
