An evaluation of current approaches for web service composition

Abstract

Since many organizations recently decided 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. In order to tackle this problem, services have to be combined together. Therefore, composition of Web services is one of the recent critical issues. Several approaches have been presented, to tackle this problem. In this paper, we classify these approaches into four categories namely workflow-based, AI-planning based, Syntactic-based, and Ontology-based. Then, we describe and compare these approaches using criteria (like QoS, scalability, and correctness). The overall results indicate that some Al-planning Ontology based approaches like HTN-DL and WSMO satisfy most of the criteria.
