In this paper we define a family of centrality measures for directed social networks from a game theoretical point of view. We follow the line started in our previous paper (Gómez et al., 2003) and, besides the definition, we obtain a characterization of the measures and an additive decomposition in three summands that can be interpreted in terms of emission, betweenness and reception centrality components.
► A family of centrality measures for directed social networks is defined. ► A game theoretical point of view is used. ► Component efficiency and a-directed fairness properties characterize these measures. ► Each measure is the city-block modulus of a three dimensional vector. ► These dimensions are emission, betweenness and reception components of the centrality.
