Abstract: Web Service composition technique provides the features to users that an individual web service cannot perform. There are several web services available over the web for performing different tasks. When there is no unique service capable of performing user request, there must be some way to sufficiently compose basic services to satisfy the user’s request. Now it becomes very important to determine which service composition system is the most efficient one. This paper presents the requirement for service composition, the required technologies to perform service composition. It also provides several different graph based web service composition techniques. At service composition time, the composition of these services depends on the requester’s inputs, outputs parameters and other non-functional parameters. Web service composition is a difficult task due to the asymmetric nature of results of the various services. In order to evaluate the best approach, various composition approaches were justified. We consider number of comparative parameters for evaluating the best composition plan.
