Metrics of network architecture

MetricDescription
Clustering coefficientThe fraction of the nodes of a given neighbor that are also neighbors of each other; reflects segregation/subspecialization in the network
TransitivityThe fraction of node triplets in the network that form a completely connected triangle; reflects segregation/functional subspecialization in the network
ModularityThe degree to which nodes tend to segregate into relatively independent modules; reflects segregation/subspecialization within the network
Characteristic path lengthMinimum number of edges required to traverse the distance between 2 nodes averaged over the network; reflects the ease of information transfer across the network
Global efficiencyInverse of the mean characteristic path length averaged over the network; reflects integration in the network
