WebI know this is a pretty old question, but just wanted to point out that the reason why your degree centrality values are all 1 is probably because your graph is complete (i.e., all nodes are connected to every other node), and degree centrality refers to the proportion of nodes in the graph to which a node is connected. Per networkx's ... WebHarmonic Centrality. Harmonic centrality (also known as valued centrality) is a variant of closeness centrality, that was invented to solve the problem the original formula had when dealing with unconnected graphs. As with many of the centrality algorithms, it originates from the field of social network analysis.
