The evaluation of the constructional significance of a node present in an organization is executed using the metric called centrality. In other words, the preeminence of a node in an organization is deliberated using the centrality metrics. The highly influential people in the online social network can be identified using these metrics. A number of measures are used when evaluating the centrality metrics, such as Degree Centrality, Eigenvector Centrality, PageRank measure, Between-ness Centrality, Closeness Centrality, and finally, the group Centrality [34].
