With the unceasing variation and evolution of user requirements and contexts, we notice that the number of Web services over internet is increasingly raising. Due to these phenomena, it appears that runtime automated service composition mechanisms are required. To achieve this goal, we propose a mechanism for adaptive and flexible service composition. The design-time components of our solution are service patterns that are used within the composition process for deriving different composition possibilities and for reducing the difficulty of the tasks of discovery and selection of the actual Web services. This mechanism relies also on a specification of user requirements structured as intentions graph. We show through this paper the steps of the proposed composition mechanism. Furthermore, we formulate a way of using OWL-S mechanisms to implement service patterns.
