摘要：Proliferation of web services opens the research arena of ontology based approach for selection of the appropriate web service(s) that satisfies the users� requirements with high accuracy. Real world ontologies tend to be large as they contain thousands of concepts and several web services are associated with them; further, several services provide similar functionalities. In such a scenario, the discovery and selection of the suitable service(s) among the equivalent services, requires a standardized approach, emphasizing on both functional and non-functional aspects. This paper proposes a Standardized Engine that incorporates a layered approach. The first layer, lexicon search, performs semantic matching using word net; second layer Concepts based refiner, is responsible for comparing the concepts available in the domain ontology; the third layer, QoS (Quality of Service) based refiner, performs a statistical analysis using QoS parameters namely response time, throughput and availability. The evaluation of the standardized engine is performed using the metrics precision, recall and f-measure.
