Centrality indices produce rankings which seek to identify the most important nodes in a network model. Different centrality indices encode different contexts for the word "importance." The [[betweenness centrality]], for example, considers a node highly important if it form bridges between many other nodes. The [[Centrality#Eigenvector centrality|eigenvalue centrality]], in contrast, considers a node highly important if many other highly important nodes link to it. Hundreds of such measures have been proposed in the literature. | Centrality indices produce rankings which seek to identify the most important nodes in a network model.
