Abstract :
The existing service selection methods consideration trust, basically consider the trust of QoS. In fact, the trust of service selection is not only about that of QoS, but the trust of the output data of Web service. However, the trust of the output data is related with the input data of Web service and the treating process of output data, that is to say, the trust of output data is related to the output data provenance. Therefore, a service selection algorithm based on the trust of data provenance is proposed in this paper, in which the trustworthiness computation tree is designed to calculate the trustworthiness of the output data treating process, and based on the trustworthiness of input data, the trustworthiness of output data is obtained, and then based on QoS and the trustworthiness of output data Web services are selected, improving the quality of service selection.
