Resumen
The current practice of design and implementation of co-authorship graphs implies the use of mathematical apparatus of graph theory. Traditionally, to build co-authorship graphs using undirected graphs. The authors of this study analysed an approach of bipartite directed graph as a tool for constructing graphs of co-authorship. The study shows the benefits of using a bipartite graph and a quantitative comparison of the traditional way of constructing the graph of co-authorship and method based on a bipartite graph using the centrality metrics of the graph.
