Group Colocation Behavior in Technological Social Networks
Figure 1
Cumulative distribution function (CDF) of the distance from Foursquare users' top locations to a check-in venue.
Top locations are the locations where a user has checked in the most in the past. ‘Closer’ refers to the distance to the closest of a pair of users' top locations in a colocation event, ‘mean’ refers to the mean distance to the users' top locations, and ‘single’ is the function for all check-ins, not just ‘social’ check-ins that make up colocations between friends. Social check-ins tend to take place closer to a top location of one of a pair of colocated friends than do general check-ins to a top location of the checking-in user.
