Abstract: Web service composition is combining various individual services into a single service which provides more reliable, value-added features than individual service cannot provide. Many individual web services are available over the internet which provides different services. But, there may be a situation when there is no unique service which completely fulfills user’s requirements. Web service composition solves this problem by combining services to satisfy the user’s requirements. There are many web service composition techniques but, which one is the efficient one is important. This paper provides an overview on web service composition with its issues. This paper also provides several different web service composition techniques that help in solving these issues. Web Service composition mainly takes into consideration the input and the output parameters along with user’s requirements. Since different individual services perform different task by taking different parameters it becomes difficult to compose services. So, to understand which approach is best, various techniques are justified by considering different parameters for evaluation.
