Abstract

Some of the metrics more commonly used for Social Networks Analysis (SNA) do not consider the weights of relationships between the actors of the analyzed Social Network, if it exists. These weights aim to measure the importance of the relational ties between actors and also are important to be considered in a SNA. This paper purposes the Gini Coefficient to be applied on Social Networks Analysis. Our initial results demonstrate the validity and applicability of this approach for a collaboration of Brazilian network scientists.
