Determining the betweenness centrality

Betweenness centrality is a type of centrality similar to closeness centrality (refer to the Calculating social network closeness centrality recipe). This metric is given by the following equation:

It is the total of the fraction of all possible pairs of shortest paths that go through a node.

Getting ready

Install NetworkX with instructions from the Introduction section.

How to do it...

The script is in the between_centrality.ipynb file in this book's code bundle:

1. The imports are as follows:

   import networkx as nx
   import dautil as dl
   import pandas as pd

2. Load the Facebook SPAN data into a NetworkX graph:

   fb_file = dl.data.SPANFB().load() ...
