Pictorial representation of the adjacency matrices of the projections of FilmTrust ((a–c), U.S. Senate (d–f) and U.S. House of Representatives (g−i), obtained within the zero-inflated scheme, i.e., the naive ones (a, d, g), the ones induced by the BiSRGM-FT b, e, h) and the ones induced by the BiSCM-FT (c, f, i). Entries equal to −1 are coloured in red, entries equal to 0 are coloured in white, and entries equal to +1 are coloured in blue. The rows and columns of these adjacency matrices are re-ordered on the basis of the mesoscopic structures spotted by minimising BIC (see also Fig. 4).
