Using contradictions improves question answering systems (2023.acl-short)
Copied to clipboard
| Challenge: | Existing systems that use contradiction to determine if a question is supported by background contexts do better than those that use entailment. |
| Approach: | They propose a method that incorporates contradiction in natural language inference (NLI) they propose to reformulate answers from QA systems as hypotheses and then select the best one based on the results. |
| Outcome: | The proposed method improves on multiple choice and extractive QA in two settings. |
