Accuracy versus F-score plane. Our methods on the accuracy versus F-score 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). In this plane, SVD alone occupies the same point as SVD-UI. The orange oval denotes the results for one of the versions of VTT (with bigrams⁺) included in the SVD-UI method. IAS, interaction article subtask; SVD, singular value decomposition; SVM, support vector machine; SVD-UI, SVD with uncertainty integration; VTT, variable trigonometric threshold.
