A survey on semantic web service discovery

Web services enhance current web functionality by altering its nature from document to service oriented. These services are self-describing, self-contained, modular applications accessible over Internet. Web service technology has gained more important role in developing distributed applications and systems on the Internet. Rapid growth of published Web services makes their discovery more and more difficult. Service discovery is one of challenging issues in semantic web services. A Semantic-based approach for WS discovery searches based on both functional and non-functional parameters and also recognizes the importance of interoperability with the Web services. Currently, most of the existing service discovering and matching approaches are based on keywords-based strategy. More services are available; the most is it becomes difficult to find the most appropriate service for a specific application. In this paper we mainly discuss about evaluating the discoverability of services through semantic web services.
