Abstract: The disclosure includes a system and method for determining an influence score for a user. The system includes a classification module, a controller, a determination module, a ratio module and a score module. The classification module creates an influence profile for a first user. The controller determines activity data associated with a set of active users. The determination module determines how frequently the activity data associated with the active users describes the first user and a second user that has a second influence score. The determination module determines a first user activity score and a second user activity score. The ratio module compares the first user activity score to the second user activity score to determine an influence ratio. The score module determines a first influence score for the first user based at least in part on the influence ratio and the second influence score for the second user.
