Geographic-area cluster
In one embodiment, a method includes determining a first set of users associated with a first geographic area; and determining one or more second sets of users. For each second set of users the users in the second set are associated with one of a number of second geographic areas and the users in the second set interact with the first set of users. The method also includes, for each second set of users, computing a mutual-interaction metric between the first set of users and the second set of users based on an amount of interaction between the users in the first set and the users in the second set; and determining, based on the mutual-interaction metric, a geographic-area cluster that comprises the first geographic area and one or more of the second geographic areas. The geographic-area cluster represents a user community that spans the first and second geographic areas.
