Graph theory betweenness

WebCloseness Centrality. The Closeness Centrality algorithm is a way of detecting nodes that are able to spread information efficiently through a subgraph. It measures the average farness (inverse distance) from a node to all other nodes. Nodes with a high closeness score have, on average, the shortest distances to all other nodes.

Centrality indices are answers to the question "What characterizes an important vertex?" The answer is given in terms of a real-valued function on the vertices of a graph, where the values produced are expected to provide a ranking which identifies the most important nodes.
