Table 8 Different centrality values calculated on the like-dislike relation network from Sampson’s Monastery social network dataset by using centrality measures for unsigned and undirected graphs. Deg, Btw, Cls, Eig and Katz are degree, betweenness, closeness, eigenvector and Katz centralities. TE and NE stand for total effect and net effect as derived from our new methodology. Deg, Btw, Cls and Eig were calculated using Netdraw (Borgatti et al. 2002)
