We believe the proposed algorithm has substantially high precision (after manually verifying many of the located answers), and we also find its recall satisfactory. Notably, in the SQuAD 2.0 training dataset, we have preserved 107,088 questions (which is 82.2% of the English ones) and in the development dataset we kept 10,845 questions, 91.3% of the original dataset. Note that the ratio of the kept data in SQuAD 1.1 is lower, because unanswerable questions of SQuAD 2.0 are always preserved.
