Discovering local attractions from geo-tagged photos

This paper presents PhotoTrip, an interactive online service which is able to recommend not widely known, but interesting, places along travel itineraries, without human intervention. These points of interest are identified by analyzing the geo-tagged pictures contained in Flickr community. PhotoTrip enriches these pictures with information provided by WikiLocations, to enhance the recommended local attractions with additional information on what is depicted in the photos to help the user to make a choice. We evaluated the system with an user study.
