Table 3: The result of ablation study.
['Model', 'task', 'dev-oracle  [ITALIC] F1', 'dev-oracle acc', 'dev  [ITALIC] F1', 'dev acc', 'test-oracle  [ITALIC] F1', 'test-oracle acc', 'test  [ITALIC] F1', 'test acc']
Next to probe the role of each component of SPADE♠, we perform ablation study. Finally, the removal of data augmentation (random token dropping and insertion, and the warping and rotation of coordinates) shows the critical role of it
