Graph coreness

WebJul 31, 2024 · Coreness can be described as the property of the node to belong to the densely connected part of the graph (higher node cores) or its periphery (lower node cores). Nodes with higher cores are typically referred to as influential nodes since they are able to spread information faster across the network than nodes with lower core values.
