A Survey on Web Service Discovering and Composition

This paper reviews the existing techniques used in the discovering and composing of services. The task of selecting an adequate service can quickly grow tedious if all services that are listed under a certain description have to be compared manually for the final selection. And what is more, the final selection does not only depend on service parameters like executions costs or accuracy, but depends on the usefulness of objects or information that service offers. This problem is present in open environments where entities like web services or agents need to locate other entities to achieve cooperation, delegation or interoperation. For these reason these two approaches, web services an agents have deal with these problem proposing an automated and efficient mechanism to determine a structural and semantic match descriptions between entities.
