Semantic Discovery of Grid Services Using Functionality Based Matchmaking Algorithm

With this paper, we propose a matchmaking system that performs matchmaking of requested grid services with that of advertised ones to discover the best suitable services. The matchmaking algorithm implemented in our matchmaking system considers functionality of the requested service as critical factor for faster and accurate discovery of services. Unlike conventional matchmaking algorithm where service discovery is based on Inputs and Outputs, our algorithm retrieves services similar to the one requested based on functionality in addition to Inputs and Outputs.
