Um estudo de hipergrafos em redes de colaboração de coautores

Abstract

We investigate the use of graphs and hypergraphs to measure network centralities, the networks used was co-authorship networks of four theorical physicist: Albert-László Barabási, Giorgio Parisi, Frank Wilczek and Donald Truhlar. The measures was made using the graph representation and the hipergraph one, during the procedure we used sub-networks to measure the centralities, because if was analysed the whole network we could face problems during the cleaning, normalization and visualization process. Besides it was compared the results usind graph and hyperhraph which formented the discution of the viability of the use of hypergraphs in networks.
