- In this paper we present CICERO, a system for the assisted planning of personalized itineraries to visit the Ducal Palace in Urbino, Italy. The graphic interface gives users a structured and exhaustive view of the artistic content of the museum, and enables them to choose consciously which aspects to privilege during the visit. According to the user preferences, the system derives a set of constraints and then determines a personalized itinerary by means of a heuristic path-planning algorithm.
