Table 5 \(F_{1}\) scores of BLOC and baseline classifiers for the detection of information operation drivers, calculated with data from the first 10 weeks of each campaign (F1@Week 10). For campaigns with less than 10 weeks of data, the entire dataset was used. Information operations are sorted by the \(F_{1}\) score of the combined method (combined F1@Week 10). The best method for each campaign is shown in bold. Note that \(F_{1}=0\) when the similarity signal used by a classifier cannot be observed in the behavior of a particular campaign’s drivers. No co-retweets were observed between any pairs of drivers in China_1
