Web services are applications that perform desired tasks. Such as basic network connectivity to sophisticated compound tasks. Service composition is the construction of complex services to enable different tasks. Therefore, enabling a rapid and effective composite of services is crucial point in efficiency of composite web services. This paper introduces a new algorithm for effective construction of the primitive services according to their quality criteria. A trust based ranking algorithm is employed to diminish the service with lower qualities.
