The framework builds on quantitative measures of segregation, called segregation indexes, proposed in the social science literature. The segregation discovery problem consists of searching sub-graphs and sub-groups for which a reference segregation index is above a minimum threshold. A search algorithm is devised that solves the segregation problem. The framework is challenged on the analysis of segregation of social groups in the boards of directors of the real and large network of Italian companies connected through shared directors.1 aBaroni, Alessandro1 aRuggieri, Salvatore  uhttps://kdd.isti.cnr.it/publications/segregation-discovery-social-network-companies
