1. A computer-implemented method for prioritizing points of interest, the method comprising: receiving a plurality of points of interest (POIs) selected for a first user in response to a search query submitted by the first user, wherein the first user has assigned ratings to at least a threshold number of points of interest in a first geographic region but not in a second geographic region, the second geographic region being at least a threshold distance away from the first geographic region; identifying a second user who has assigned ratings to at least the threshold number of points of interest in both the first geographic region and the second geographic region; identifying at least one point of interest in the plurality of POIs that has been assigned a rating by the second user, wherein the at least one identified point of interest is in the second geographic region; prioritizing the at least one identified point of interest among the plurality of POIs based on the rating by the second user of the at least one identified point of interest; and selecting, based on the prioritizing, a subset of the plurality of POIs to be presented to the first user.
