Achieving Web services composition – A Survey

Abstract Web Services composition development is too complex and dynamic. Software engineering approach is adopted to develop composite service systematically. Co mposition development process involves modelling, discovering & binding, publishing and invoking a co mposite service. Th is paper aims to make the co mposition development process clear by classifying the literature on web services composition into the phases of composition development process. As a result of this, the definit ion, requirements, approaches, techniques and evaluation of an end-to-end web services co mposition development process is made clear. The current research area which requires a lot of attention is identified and discussed at the end to further extend the topic

International Journal of Web Services Research, Vol.X, No.X, 200X Search Strategies for Automatic Web Service Composition 1 ABSTRACT:

We investigate architectural properties required for supporting automatic service composition. First, composable service architecture will be described, based on modeling Web services as abstract machines supported by formally defined composition operators. Based on the proposed infrastructure we give several options for achieving automatic service composition by treating it as a search problem. Namely, basic heuristic, probabilistic, learning-based, decomposition and bidirectional automatic composition mechanisms will be presented and compared. Finally, we discuss the impact and outlook for automatic composition. KEY WORDS: Web services, automatic compositio
