At 402, for each pair of bicliques (Ci, Cj) from list L having a score o meeting a threshold based on a number of overlapping nodes and a size of the each pair of bicliques, the flow conducts calculations for the weight of the missing links as described in 403. In an example implementation, the score can be based on a number of overlapping nodes meeting a threshold and a size of the each pair of bicliques, and a threshold can accordingly be set to the desired implementation. An example formula for calculating the score o can be as follows:
