When visiting cities as tourists, most users intend to explore the area looking for interesting things to see or for information about places, events, and so on. An adaptive information system, in order to help the user choice, should provide contextual information presentation, information clustering and comparison presentation of objects of potential interest in the area where the user is located. To this aim, we developed a system able to generate personalized presentation of objects of interest, starting from an annotated city-map.
