illustrate how the system adapts to the publication of the
groundbreaking paper by Watts'98. The network was derived from 5,135 articles
published on small-world networks between 1990 and 2010. The network of 205
references and 1,164 co-citation links is divided into 12 clusters with a modularity
of 0.6537 and the mean silhouette of 0.811. The red lines are made by the
top-15 articles measured by the centrality variation rate. Only major clusters'
labels are shown in the figure. Dashed lines in red are novel connections made
