aCalculated from 51 runs submitted by 19 teams. AUC, area under the curve; IAS, interaction article subtask; SVD, singular value decomposition; SVM, support vector machine; SVD-UI, SVD with uncertainty integration; VTT, variable trigonometric threshold. Bold entries for accuracy, F-Score, and AUC denote best value obtained for all our submitted runs.
