Abstract :
During service-based systems (SBS) development, the qualities of service (QoS) are significant factors to compose high-quality workflows and the QoS claimed by service providers may be not trustworthy enough. In this paper, a reputation system supervising both service providers and service clients without much monitoring cost is introduced. The approach is based on the claimed QoS deviation from the feedback QoS reported by monitors or clients and is able to provide more trustworthy predicted QoS. An experiment conducted at last validates that the reputation system is effective and efficient.
