Emergence of Multiplex Communities in Collaboration Networks

Intra-layer, inter-layer and mixed assortativity in collaboration networks.
We show the intra-layer (a), inter-layer (b) and mixed (c) degree-correlations for couples of layers of the IMDb and APS collaboration networks. Real data (dots) are compared with the results of our model (solid lines) generated with the extracted values p and p*. The symbols (^) indicate that the reported quantities (both for the model and the data) have been normalised to the values observed in the corresponding configuration model. As shown, the model is in general able to correctly capture the assortative trends of the three different types of correlations. Very good agreement with the data is attained in the case of the movie actor collaboration network. Less precise results are obtained for the APS network, where we deal with a system of considerably smaller size.
