Weighting of the edge by Normalize SimilarityIndex (NSI).

and are connected with one directed edge (Cij = 1). Node and are also connected with four common node (Vm−1,Vm−2,Vm−3,Vm−4), and in total with eight distinct neighbors (Vm−1,Vm−2,Vm−3,Vm−4,Va, Vb, Vc, Vd). The NSI will then be NSIij  = 5/9 = 0.55.
