Fig. 2From: Effective comparative analysis of protein-protein interaction networks by measuring the steady-state network flow using a Markov modelIllustration for constructing the integrated network from a network pair. Dotted lines in the left figure indicate the pairwise node similarity, in which the thickness of each line is proportional to the pairwise node similarity. To construct the integrated network, we insert an edge between each pair of nodes across different networks if they have positive pairwise node similarityBack to article page
