Robust link prediction in criminal networks: A case study of the Sicilian Mafia

2020

Abstract Link prediction exercises may prove particularly challenging with noisy and incomplete networks, such as criminal networks. Also, the link prediction effectiveness may vary across different relations within a social group.
