Context-Aware Places of Interest Recommendations for Mobile Users

Recommender Systems (RSs) are software tools and techniques pro- viding suggestions for items, such as movies, CDs, or travels, to be of use to a user. In general, a recommendation can be more compelling and useful if the context of the user is known. For instance, in a travel recommender, the season of the travel, or the group composition, or the motivation of the travel are all important contextual factors that, as a traveler normally does, should be taken into account by a system to generate more relevant recommendations. In this paper we show how a context-aware mobile recommender system for places of interest (POIs) selection can generate more effective recommendations than those produced by a non context-aware version, i.e., those normally provided to the city visitors by the local tourist office. Here we mainly focus on the HCI so- lutions and in particular in the explanation of the recommendations that are per- ceived by the user as an important element of the graphical interface.
