An efficient approach for dynamic selection of Web Service in service-oriented goal based framework

Selection of a suitable and apposite web service for a particular goal oriented job has become a difficult challenge due to the increasing and huge number of web services offering similar functionalities. When dynamic discovery is used in Web Services to select a specific service in optimal way, it is familiar that the outcome of the discovery contains more and supplementary than one provider. From this bulkiness and massiveness, it is tough enough even for a sophisticated user to find out the matter of interest due to syntactical match based searching. Researches are now able to impart semantics to the web services so that the response to the client might be more specific. But in this case also, there is a possible chance of generation of diverse sets of web services which may confuse the naive user. In this paper we introduce a novel concept of matchmaking of semantic web services with the user´s goal. Here instead of invoking different sets of web services, the system will generate only one of the best choices available in the repository. This paper studies the dynamic Web service selection problem in a service-oriented environment. A usage scenario on ehealth system using the propose algorithm has been evaluated here in brief.
