摘要
Web Services provided a new way of distributed computing that achieve the interoperability between heterogonous application through platform and language independent interfaces. The creation of value-added services by composition of existing ones is gaining a signicant momentum. Since many available Web services provide identical functionality, albeit with different Quality of Service(QoS), a selection needs to be made to determine which services are to participate in a given composite schema. So, QoS-based dynamic web services composition has now received much attention. This paper proposed the conception and definition of the compositionly, gave the expression to calculate the single service' and the composition service' compositionly, and added compositionly criterion to QoS model. On this basis, we design a new method to select the services which satifis user from candidate services, which can work better with little time in large number of candidate services.
