A review of web service composition approaches
Wan Mohd Nasir Wan Kadir, Sayed Gholam Hassan Tabatabaei, Suhaimi Ibrahim · 2008
Nowadays since many companies decide to implement and publish their applications over Internet, the number of Web services has dramatically increased. In many cases, a single service is not sufficient to respond to the user's request. Thus to solve this problem, services should be combined together. For example, if a user wants to participate on one international conference, it is not sufficient to register, but he should also take care of booking a flight, reserving a hotel, renting a car, and so on. Thus, composition of Web services is one of the recent critical issues. A number of approaches have been presented, to solve this problem. In this paper, we classify these approaches to three categories (Workflow-based, XML-based, and Ontology-based) and describe them. Then, we compare these approaches based on some benchmarks (like QoS, scalability, and correctness).
