Interest communities at all scales as detected by Markov Stability. (a) The number of communities at each Markov time (t). The inset shows the network with nodes and edges coloured according to their community at four illustrative Markov times. Two of these partitions at different resolutions are shown in more detail. (b) At relatively short Markov times (t_I = 0.15), we find 149 communities (coarse-grained network view in the centre). Three examples of communities in this partition are ‘police and crime reporting’ (top), ‘Hackney’ (bottom), ‘the Daily Telegraph’ (left) shown with their members and their self-description word clouds. (c) At longer Markov times (t_IV = 7) we find four communities (coarse-grained view in the centre): three large communities broadly corresponding to ‘UK’ (bottom-right), ‘international’ (top), ‘celebrities/entertainment’ (bottom-left) and a small one corresponding to the ‘BBC’ (right). A detailed view of the partitions can be found in the electronic supplementary material.
