Service offer driven dynamic selection mechanism for business web services

Abstract

Web service selection is a mechanism to select the most suitable web service that satisfies the requester’s various non-functional requirements. In e-business environment, the business offers (service offers) play a major role in attracting numerous consumers. To find the most profitable (in terms of service offer) web service, there is a need for the selection mechanism to rank the functionally similar business driven web services based on the provider’s service offers and the requester’s requirements on them. In this paper, the authors define a tree structure called service offer constraint tree ( SOCT ) to model the requester’s demands on the service offers of business web services. The authors explore the selection mechanism which selects and ranks the functionally similar business web services based on the requester’s service offer requirements and preferences. The paper also presents the broker-based architecture for business driven web service selection which facilitates the publishing and selection.
