A node's centrality score is an index that
identifies its importance inside a network. Depending on
the goal of the study, different writers define different
centrality measures. Numerous fields, including sociology,
neurobiology, communication networks, electrical
networks, etc., find use for these measurements. The goal
of this work is to provide a thorough overview of degree,
closeness, eigen vector, and betweenness centrality.
Keywords : Centrality Measure; Degree Centrality; Closeness Centrality; Eigen Vector Centrality; Betweenness Centrality.
