Centrality measures in social networks is the centrality of of node i in the social network g. 2 Here are some of the key centrality measures from the literature. 3 Degree centrality Degree centrality measures the number of edges of node i, di(g). We. There are various metrics that are used in social network analysis to estimate/find the influence of a node. Among them are various - betweenness centrality, closeness centrality and eigenvector centrality (Learning agent influence in MAS with complex social networks, 2013 by H. Franks, H. Griffith and S. S. …

Identifying influential peers is an important issue for business to promote commercial strategies in social networks. This paper proposes a conductance eigenvector centrality (CEC) model to measure peer influence in the complex social network. . Eigenvector centrality expands upon the notion of the degree of a node, incorporating information about the degree of a node’s alters. While the degree for node A in a social network measures how many ties A has, the eigenvector centrality of node A is measured based on how many ties A’s alters have.

Eigenvector centrality characterizes the global centrality of a node in a network and it is the most interesting indicator for our study, along with betweenness which indicates where a node possesses the shortest path between other. Centrality in social networks 2 17 Thus, the idea of centrality is alive and well and is being mobilized in an ever widening range of applications.
