1. A method for determining risk root cause link, the method comprising:

  • determining, by a computing device, a first and second fraud related risk scores respectively associated with a first and second nodes;

    determining, by the computing device, a relation strength value related to at least one relation between the first and second nodes; and

    using by the computing device, a value function that monotonically increases according to the first and second node risk scores and the relation strength value to calculate a cluster risk score for a cluster of nodes, the cluster including at least the first and second nodes; and

    wherein calculating a cluster risk score comprises;

    determining at least one path between a first and second nodes, the at least one path including at least one relation between two nodes included in the cluster;

    determining a relation strength value of at least one relation included in the path and a first and second node risk scores respectively associated with the first and second nodes; and

    calculating the cluster risk score based on the relation strength values and based on the node risk scores.
