Web Service Selection Based on Requester's Offering Constraints

Web service selection is a mechanism to select the most suitable Web service that satisfies requester's various non-functional requirements. In e-business environment, the business offers play a major role in attracting a numerous consumers. In order to find the most profitable service offering a valuable business offer, there is a need for the selection mechanism to rank the functionally similar Web services based on the provider's business offers and the requester's requirements on various business offers. In this paper, we propose an XML model to represent requester's complex requirements on multiple business offers. The paper explores the Web service selection mechanism which selects and ranks the functionally similar Web services based on the requester's requirements on business offers. The paper also presents the broker based architecture for business offer aware Web services publishing and selection. Finally, we present a scheme to represent the requester's alternative requirements on business offers and extend the selection mechanism to handle a set of alternative business offering requirements.
