13. The method of claim 1 , wherein calculating an aggregate probabilistic utility score further comprises: obtaining a destination-utility factor indicative of utility of one of the other candidate geographic locations to the user irrespective of distance; and calculating the aggregate probabilistic utility score based on the trip-utility factor.
1. A method to provide internet-based services targeted to a geographic location, the method comprising: receiving a request from a user to provide internet-based services based on a target geographic location; obtaining a plurality of candidate geographic locations associated with the user, each candidate geographic location being associated with a respective candidate confidence level; calculating, with a computer, for one of the candidate geographic locations, a respective aggregate probabilistic utility score, the aggregate probabilistic utility score being based, at least in part, on distances from the respective candidate geographic location to the other candidate geographic locations and the confidence level scores of the other candidate geographic locations; selecting a geographic location based, at least in part, on the aggregate probabilistic utility score from among the candidate geographic locations; and providing internet-based services to the user targeting the selected geographic location.
