Web Services are self contained and self described modular applications that can be published, discovered and employed on the Web. Many standard protocols supporting web services have been adopted and more are being proposed. In this paper, we study the issues on providing intelligent web services. We propose the enhancement of web service functionalities by deploying software agents on both server side and/or client side. Our goal of designing the WISE web service architecture is to provide a working middle ground between the current web service standards and the Semantic Web architecture. The WISE software agent architecture for web services is presented. We discuss the design issues of WISE. We also present the QoS management protocol and algorithm that can be used by WISE servers.
