Figure 5. Evaluation of I ^score via ROC curves with composite reference standards for the five networks.

(a) T ₀ = 10%. A node is defined as important if either its rankings by the in, out, total degree, PageRank, motif centrality or the betweenness are at the top-T ₀ level. (b) Similarly to (a), but with T ₀ = 20%.
