R Documentation

Function to compute the Betweenness Centrality ranking.

Description

This function computes the Betweenness Centrality (BC) for each graph node (i.e. publication).

Usage

compute_BC_ranking(gr, labels, write_to_graph = F)

Arguments

gr	Citation graph
labels	Labels (i.e. names) of the two corpora featured in the graph.
write_to_graph	Flag to indicate whether to write results to the graph (i.e. save BC values as node attributes).

Value

If write_to_graph is FALSE, returns a list of entries (authors, title, year, corpus, BC) sorted by decreasing BC. Else, returns the graph given as input to which BC values are added as node attributes.
