After constructing the graph to model the repository, it is amenable to standard graph algorithms. For this approach, we’ll turn to a popular algorithm for identifying the “key” elements of a graph called betweenness centrality. This algorithm assigns an integer score to each vertex; the higher the score, the more “central” the vertex. A vertex score is incremented if it falls on the shortest path between any two other vertices in the graph.
