Fig. 4

Fingerprint maps of the key concepts in the collated concept network. The key concepts having a high communicability are shown as black stripes. The weighting of links with β=10p changes from p=−2 to p=2 as shown on the scale on the right. The communicability through out-going links (OUT) is shown in the upper panel and through in-coming links (IN) in the lower panel. Numbering of nodes is given in upper- and lower sides of the stripes. The colour-legend for relative strengths of communicability is provided on the right. Note how differently weighted networks have different sets of key nodes. The key nodes surviving after the strong epistemic weighting region are the most strongly supported/supporting ones
