This paper presents a view-based approach for tracking personalized Web services. Web services are subject to personalization when there is a need to accommodate user preferences during these Web services performance and delivery of this performance's outcome. Preferences are of multiple types such as when the execution of a Web service should be initiated and where the outcome of this execution should be returned. To guarantee that these preferences are handled during Web services execution, a view offers the opportunity of zooming into the specification that composes Web services. As time advances, location changes, or constraint on the environment becomes satisfied, the deployment of a view over a specification progresses, featuring the dynamic nature of tracking personalized Web services. © 2005 IEEE.
