The Web service composition has received much attention recently to support business-to-business enterprise applications integration. Many composition approaches, languages, platforms, and patents have been proposed to overcome this issue. In this paper we present some of Web service composition languages, platforms, patents, and composition strategies, we compared them to some of the features that must be held by composition process, features such as the dynamic adaptation, execution monitoring, and quality of service (QoS) constraints to satisfy clients requirements to execute Web process. And we give an outlook to essential future research work. Recent patent and research advances aim to find methods for dynamic learning and redesigning along with monitoring and optimization of Web service composition process to satisfy user constraints.
