We evaluate our methodology on benchmark networks of four datasets obtained from the study by [16], which cover four species: yeast, human, mouse, and fly. The Yeast dataset includes 44 functional association networks, the Human dataset includes 8 networks, the Mouse dataset consists of 10 networks, and the Fly dataset has 38 networks. These datasets are publicly available at http://morrislab.med.utoronto.ca/~sara/SW/, and more information about them can be found in [16].
