Papers with textual question answering
Robust Question Answering Through Sub-part Alignment (2021.naacl-main)
Copied to clipboard
| Challenge: | Current textual question answering models fail to generalize to out-of-domain settings. |
| Approach: | They propose to decompose question and context into smaller units and align them to find the answer. |
| Outcome: | The proposed model is more robust than the standard BERT QA model on adversarial and out-of-domain datasets. |
Towards Graph-hop Retrieval and Reasoning in Complex Question Answering over Textual Database (2024.lrec-main)
Copied to clipboard
| Challenge: | Existing benchmarks for textual question answering only focus on single-chain or single-hop retrieval . Existing approaches to answer complex questions have limitations . |
| Approach: | They propose to conduct Graph-Hop, a novel multi-chains and multi-hops retrieval paradigm in complex question answering. |
| Outcome: | The proposed model provides explicit and fine-grained evidence graphs for complex question to support comprehensive and detailed reasoning. |
