Web Service has been playing a significant role in application development and integration. It facilitates pre-built applications/application components enclosed as Web Services to interact with each other via consistent interfaces and form larger application systems. This paper deals with a proper technique to Web Services identification, which is an important step in designing and developing effective Web Services. Discovery of a suitable Web Service for a particular task has become a challenging issue due to the increasing number of Web Services offering similar functionalities. The functional properties describe what the service can do and the nonfunctional properties depict how the service can do it. There is a need to select the most appropriate Web Service based on the customer's QoS requirements and preferences.
