There are three types of centralities:
- Degree centrality: measuring a node’s centrality by its in/out degree (i.e., how many in/out nodes are connected to a this node);
- Closeness centrality: measuring centrality by summing the distance from a given node to all the other nodes;
- Bewteenness centrality: measuring a given node’s centrality by counting the number of times it lies on the shortest path between two other nodes.
