Network characteristics	Definition	Calculation method
Degree centrality	The degree of relevance of a node to other nodes
Aggregation coefficient	Error propagation effect between nodes
Mesoscopic centrality	The number of the shortest paths through a node
Proximity centrality	The proximity of a node to other nodes
Centrifugal centrality	The distance from a given starting node to the farthest node
Eigenvector centrality	Number and importance of neighbor nodes
Average neighbor degree	The average of the degrees of all nodes
