This paper represented a component service aggregation mothod based on scenario to deal with the autonomous aggregation of Web services according to user's requirement.And introduced UCM to indicate scenario.According to scenario ontology,proposed a scenario-based responsibility-component service behavior mechanism to specify user requests and the capability of autonomous Web services.Gave a requirement driven component service aggregation model based on scenario,in this model,used the method of integrating functional matching with quality matching in service aggregation.Accordingly,gave a requirement driven component service aggregation algorithm and a QoS-based service optima algorithm.As a result,improved the efficiency and precision of service discovery.Finally,gave a case study and simulation experiment to verify the correctness and effectiveness of the proposed method.
