Before revision:  a directed graph of 9.3 million nodes and 169.9 million edges . Recently, Twitter released datasets on the misinformation campaigns of 8 , 275 state-sponsored accounts linked to Russia, Iran and Venezuela. These data serve as a ground-truth identifier of troll users in our dataset. Using graph analysis techniques along with a game-theoretic centrality measure, we quantify the influence of all Twitter accounts (authentic users and trolls) on the overall information exchange as is defined by the retweet cascades.
