Key players are those elements in the network that are considered important, in regard to some criteria. One of mostly popular criteria the centrality of vertex. In graph theory and network analysis, there are various measures of the centrality of a vertex within a graph that determine the relative importance of a vertex within the graph. Degree centrality, betweenness centrality, closeness centrality, and eigenvector centrality are the four measures of centrality that are widely used in network analysis. Freeman defined the betweenness measure as sums the proportion of shortest paths from one node to another that pass through a given node. A node with high betweenness centrality is responsible for connecting many pairs of nodes via the best path, and deleting that node should cause many pairs of nodes to be more distinctly. Deleting that node should cause many pairs of nodes to become fully disconnected or at least more distantly connected.
