Copied to clipboard
| Challenge: | Existing models for extractive reading comprehension are not good at deciding whether no answer is presented in the context. |
| Approach: | They propose a data augmentation technique by automatically generating relevant unanswerable questions according to an answerable question paired with its corresponding paragraph that contains the answer. |
| Outcome: | The proposed model performs better on the SQuAD 2.0 dataset than the baseline model and the BERT-large model. |

| Challenge: | Existing approaches to build robust question answering models are too complex . antonym and entity swaps on answerable questions are used to build models . |
| Approach: | They propose a method for performing antonym and entity swaps on unanswerable questions. |
| Outcome: | The proposed method outperforms the previous state-of-the-art and has higher human-judged relatedness and readability. |
