Exploiting Problem Solving Techniques to Support Web Users in Complex Tasks

The large number of non-expert users of Web-based systems need an intelligent and flexible support, even in complex tasks, and we think that problem solving techniques could be exploited to face this challenge. However, users should not be exposed to the complexity of the implementation of the reasoning mechanisms. In this paper, we present STAR, a Web-based system that exploits the configuration technology in order to support a tourist in organizing a personalized agenda for a tour in a city. We describe the overall architecture, focusing on the mechanisms that enable the system to hide the complexity of the underlying technology and to provide users with a user-friendly interaction.
