Table 2 Description length for each combination of layers in the multilayer stochastic block model. We compute the average description length (DL), Eq. (7), for each model class alongside the standard deviation over multiple MCMC runs. We also retrieved the minimum DL (MDL) over all the runs. The DL of the Text layer exceeds the Hyperlink and Metadata layer by several orders of magnitude, thus contributing the most to the Hyperlink + Text model
