Non Functional Requirementt Based Semantic Web Service Composition

M. Hima Bindu

Abstract :

The paper presents automated semantic web service composition based on non–functional requirements(web services like fastest or cheapest). An important advantage of this approach is that the composition process of web services are optimized. Automated web services composition is being critical with the increase in the number of available services day to day. The response for user queries need to be faster. Semantic information is used for discovery and composition process as well as for approximating the optimal composite services. The model devised in this paper focuses on the addition of the OWL–S descriptions of produced composite services to accelerate the composition process. It also deals with enhancing the approach with the ability to produce various composite services according to non–functional user requirements. This could be possible by extending existing web service description.
