WebApr 30, 2008 · We defined a precise measure of ‘small-world-ness’ S based on the trade off between high local clustering and short path length. A network is now deemed a ‘small-world’ if S >1 - an assertion which may be tested statistically. We then examined the behavior of S on a large data-set of real-world systems. WebNov 7, 2024 · Based on previous studies 28, we obtained the characteristic path length (CPL), global clustering coefficient (GCC), small-worldness (SMW), and betweenness centrality (BET) of each node (Fig. 1).
