- The number of shortest paths that pass through the node, which identifies the locations that sit between the others on the routes through the network.
- The share of the node's neighbors that are also connected to each other, expressed as a value between zero and one, which describes how tightly the neighborhood is knit together around that node.
- The number of relationships attached to the node, weighted by the sum of the positive values found on the relationship property used as the weight for the run.
