PageRank for ranking authors in co-citation networks
TL;DR: It is found that in the author co-citation network, citation rank is highly correlated with PageRank with different damping factors and also with different weighted PageRank algorithms; citation rank and PageRank are not significantly correlated with centrality measures; and h-index rank does not significantly correlate with centraly measures but does significantly correlates with other measures.
