Fig. 2

Size distributions of inventor communities found by different algorithms. Shown here are distributions for the number of nodes within the communities identified on the largest connected component of the co-inventor network by the Greedy, Louvain, Infomap, Random-Walks, and Propagating-Labels algorithms. Note the different bin widths: 50 (5) nodes in the plots in the first (second, third) row. For Propagating Labels (Random Walks), one community with 262 nodes (twelve communities with 163, 169, 172, 175, 194, 222, 346, 387, 393, 583, 656, and 1 060 nodes, respectively) is (are) outside the displayed range.
