Redes de Coautoria da Base SciELO: avaliação da colaboração científica por medidas de centralidade de redes complexas

Abstract

In bibliometrics field, studies have been carried out to quantitatively and qualitativelymeasure the evolution of the production of scientific knowledge. In this direction, co-authorship networks is one way of indicating the interaction between authors, through the collaborative effort between people, institutions and countries for the production and publication of a scientific work. This work seeks the proposition of an investigative analysis based on the index database of SciELO scientific articles, using for that purpose, properties and metrics of graph theory and complex networks, such as degree centrality, betweeness centrality and closeness centrality, proposing a evaluation of the global co-authoship network of the Federal Universities of Brazil and the local network, defined as focal point at the Federal University of Alagoas, for a time series from 2008 to 2017 in the areas of Health Sciences, Agricultural Sciences, Exact and Earth Sciences. This work was based on amethodology that consisted of the steps: a) definition of the network, b) data treatment, c) determination of structural characteristics, d) visual inspection. The results were generated numerically and graphically, allowing evaluations and interpretations of the behavior of the networks studied based on the centralitymeasures used in this work.
