Copied to clipboard
| Challenge: | Existing Question-Answering (QA) datasets contain unanswerable questions . however, their treatment in QA systems remains primitive . |
| Approach: | They propose a framework that provides answers based on presupposition failure over oracle behavior of existing QA systems. |
| Outcome: | The proposed system provides responses based on presupposition failure over oracle behavior of existing QA systems. |
WiCE: Real-World Entailment for Claims in Wikipedia (2023.emnlp-main)
Copied to clipboard
| Challenge: | Textual entailment models are increasingly used in fact-checking, presupposition verification in question answering, or summary evaluation. |
| Approach: | They propose a new fine-grained textual entailment dataset built on natural claim and evidence pairs extracted from Wikipedia that provides en-tailment judgments over sub-sentence units of the claim and a minimal subset of evidence sentences that support each subclaim. |
| Outcome: | The proposed dataset improves on multiple datasets at test time and shows that real claims involve verification and retrieval problems that existing models fail to address. |
