Endorsement abuse detection via social interactions

Abstract

Endorsement abuse detection via social interactions is described, including generating an endorsement log comprising an endorser identifier, a target identifier, endorsement data, and a token indicative of an endorsement event; analyzing the endorsement log with respect to a user aggregator and a target aggregator, to generate an online endorsement abuse candidate; generating an endorsement overlap graph for the online endorsement abuse candidate based on the endorsement log, the user aggregator and the target aggregator, wherein nodes of the endorsement overlap graph represent ones of the online endorsement abuse candidate, and edges represent a number of shared endorsements; and determining whether the endorsement event is authorized based an analysis of the endorsement overlap graph and an orthogonal signal at least one of transmitted and received by the ones of the online endorsement abuse candidate.

What is claimed is: 
     
         1 . A computer-implemented method, comprising:
 generating a graph comprising nodes and edges, where each of the nodes represents an endorser; each of the edges, between two of the nodes, represents endorsement targets shared by the two nodes; and the edge is associated with a weight based on the endorsement targets shared by the two nodes;   identifying one or more of the edges based on associated weights that meet at least one criterion;   identifying nodes connected to the identified edges; and   outputting the nodes connected to the identified edges.   
     
     
         2 . The method of  claim 1 , wherein the associated weights that meet at least one criterion comprises the associated weights that exceed a threshold value. 
     
     
         3 . The method of  claim 1 , further comprising taking an action against at least some of the identified nodes. 
     
     
         4 . The method of  claim 1 , further comprising taking an action against at least some endorsements by the endorses associated with the identified nodes. 
     
     
         5 . The method of  claim 1 , further comprising adding at least some of the identified nodes in a database for immediate blocking action. 
     
     
         6 . The method of  claim 1 , wherein the endorsement targets include at least one of a “+1,” like, comment, recommendation, suggestion, star rating and vote.
