摘要	In order to improve the precision of service composition, a QoS-based and similarity-based service composition method is proposed, which introduces the similarity, which is calculated by service discovery phase, into Web service composition phase. First, normalize the individual service QoS. Secondly, polymerize the workflow and calculate the QoS of individual service. Make combination between QoS and service discovery phase of its similarity to analysis the final score of a single service. Finally, fetch the workflow execution path by using backtracking algorithm. Experimental results show that the precision of QoS-based and similarity-based service composition algorithm precision is better than the precision of traditional QoS-based service composition algorithm.; In order to improve the precision of service composition, a QoS-based and similarity-based service composition method is proposed, which introduces the similarity, which is calculated by service discovery phase, into Web service composition phase.
