1. A method for associating a content item with an event, comprising: determining a location associated with a received content item; and associating the received content item with an event, at least in part based on an indicia of relatedness, other than the determined location, between the received content item and the event; wherein a criterion that the indicia of relatedness is required to satisfy for the content item to be determined to be associated with the event has a lower value if the determined location associated with the received content item has a first degree of correspondence to a location associated with the event than if the determined location associated with the received content item has a second, lower degree of correspondence to the location associated with the event.
