Survey of services composition technique research on web services

As a new value-added web services technique for reusing, web service composition has been gathering an increasing amount of attention lately. From the point of the development of distributed computing, this paper analyzes the characteristics and the life-cycle model of next generation of web services-based distributed computing. Furthermore, the conceptions, properties and goals about the composition of web services are reviewed, and the composition methods and classifications and composition logic and structures are analyzed. In addition, four kinds of web service composition strategies can be divided as framework-based static composition, workflow-based dynamic composition, semantic-based automatic composition and software architecture-based syntheses composition. Finally, the mainly research fields and trends of service composition technique and the vital problems and challenges existed in the process of composition are analyzed and reviewed.
