Business agility is an important challenge while designing an enterprise application. Service oriented architecture is used to combine many outsourced web services to provide value added services to the users with agility. A service registry is maintained to keep track of various web service published by the service providers. The key challenge for the service requester is to pick the best web service among the various functionally equivalent web services in the service registry. This paper describes and analyses various service selection protocols given by the researchers. The approaches are classified into semantic and non-semantic approach. It also proposes a novel technique to look for the best web service based on QoS like reliability, throughput etc. The solution to the problem of selecting the best web service according to the requirements is designed as a fuzzy expert system. This rule based approach of Service registration and lookup is adaptive and responds dynamically to quality of service changes in the web services.
