Patent ID: 8706647

Claim:
Non-transitory, tangible, computer-readable storage media containing a program of instructions configured to cause a computer system running the program of instructions to function as a computer valuation system that determines a social influence value for a user of a computer network system by performing the following algorithms: using a computer hardware input device to receive: relationship information indicative of potentially-influential social relationships between the user and other users; and action information indicative of actions taken by the user and other users while using the computer network system; using a computer data processing system to calculate the social influence value (SIV) of user (U) of the computer network system (G) for an action (A) identified in the action information, using the equation SIV(U, A, G)=Σu j in V−{U} [{Pr(u j , A|G)−Pr(u j , A|G {−U} )}*value (u j , A)] where: Pr(u l , A|G) is the is the probability of other user u j performing the action with user U present within a data set, Pr(u j , A|G {−U} ) is the probability of user u j performing the action with user U absent from the data set, V−{U} is the set of all other users except for user U, and value (u j , A) is revenue generated for user u j performing the action; and using a computer hardware output device to deliver the social influence value for the user.
