Predicting the Role of Political Trolls in Social Media
Table 3: Predicting the role of the troll users using full vs. distant supervision.
['[BOLD] Method', '[BOLD] Full Supervision (T1)  [BOLD] Accuracy', '[BOLD] Full Supervision (T1)  [BOLD] Macro F1', '[BOLD] Distant Supervision (T2)  [BOLD] Accuracy', '[BOLD] Distant Supervision (T2)  [BOLD] Macro F1']
Each line of the table represents a different combination of features, models, or techniques. The tags ‘LP1’ and ‘LP2’ denote the two label propagation versions, by mention and by similarity, respectively. Indeed, the results for T2 are lower compared to their T1 counterparts by only 10 and 20 points absolute in terms of accuracy and F1, respectively. This is impressive considering that the models for T2 have no access to labels for troll users.
