Figure 4From: A multi-layer approach to disinformation detection in US and Italian news spreading on TwitterTwo illustrative examples of diffusion layers. Left: The same news spreads, in a pure top-down broadcast manner, along two distinct cascades. Thus, SCC equals the number of nodes, since each strongly connected component is a single node, while WCC is the number of distinct cascades. Right: The two cascades merge in a common node (thus WCC = 1) and, additionally, mono-directionality is broken by a loop (thus SCC is less than the number of nodes)Back to article page
