Semantic Web Service Composition Approaches: Overview and Limitations

Service composition is gaining popularity because the composite service presents the features that an individual service cannot present. There are multiple web services available over the web for different tasks. Semantic web is the advance form of the current web, where all the contents have well defined meanings, due to this nature; semantic web enables the automated processing of web contents by machines. At run time, the composition of these services based on the requester’s functional and nonfunctional requirements is a difficult task due to the heterogeneous nature of results of the services. This paper introduced some requirements that when fulfilled, a successful composition process can be achieved. In order to find the best approach, various composition approaches on these requirements were evaluated. Suggestions were provided on what approach can be used in which scenario in order to gain the best results.
