Accuracy versus AUC plane. Our methods on the accuracy versus AUC plane for IAS. Mean and median are for the set of all submissions from all groups. Red squares denote our three submissions (SVM, VTT, and SVD-UI). The orange polygon denotes the results for SVD alone, and the orange oval denotes the results for one of the versions of VTT (with bigrams⁺) included in the SVD-UI method. AUC, area under the receiver operating characteristic curve; IAS, interaction article subtask; SVD, singular value decomposition; SVM, support vector machine; SVD-UI, SVD with uncertainty integration; VTT, variable trigonometric threshold.
