| Approach: | They propose a framework that decomposes the task into three stages: question generation, question answering, and rewriting. |
| Outcome: | The proposed framework decomposes the task into three stages: question generation, question answering, and rewriting. |

Peek Across: Improving Multi-Document Modeling via Cross-Document Question-Answering (2023.acl-long)
Copied to clipboard
| Challenge: | Among recent NLP research, multi-document processing is gaining increasing attention due to the need to handle and process an increasing amount of textual data and available documents online. |
| Approach: | They propose to pre-train a generic multi-document model from a cross-document question answering pre-training objective by generating salient sentences from one document and challenging it to recover the sentence from which it was generated. |
| Outcome: | The proposed model outperforms zero-shot GPT-3.5 and GPT-4 in multiple document tasks and generates the correct answer and the salient sentence from a salient document. |
Decontextualization: Making Sentences Stand-Alone (2021.tacl-1)
Copied to clipboard
| Challenge: | Taking excerpts of text can be problematic, as key pieces may not be explicit in a local window. |
| Approach: | They define a problem of sentence decontextualization by rewriting a sentence to be interpretable out of context while preserving its meaning. |
| Outcome: | The proposed method can be used in question answering and document understanding tasks. |
Towards Multi-Document Question Answering in Scientific Literature: Pipeline, Dataset, and Evaluation (2025.findings-emnlp)
Copied to clipboard
| Challenge: | Existing QA systems do not strictly enforce cross-document synthesis or exploit the explicit inter-paper structure that links sources. |
| Approach: | They propose a pipeline methodology for constructing a multi-document academic QA dataset . they detect communities based on citation networks and leverage Large Language Models . |
| Outcome: | The proposed method generates QA pairs related to multi-document content automatically and forms coherent communities based on citation networks and large language models. |
Can You Unpack That? Learning to Rewrite Questions-in-Context (D19-1)
Copied to clipboard
| Challenge: | Existing QA datasets lack key NLP problems like coreference and ellipsis resolution. |
| Approach: | They propose a task of question-in-context rewriting to rewrite a context-dependent question into a self-contained question with the same answer. |
| Outcome: | The proposed task is based on a dataset of 40,527 questions based in QuAC . it requires models to link questions together to resolve conversational dependencies . |
Improving Question Answering with External Knowledge (D19-58)
Copied to clipboard
| Challenge: | ARC-Easy, ARC Challenge, and OpenBookQA use Wikipedia to augment training data . performance degrades when additional instances exhibit higher difficulty than original training data. |
| Approach: | They propose two methods for exploiting external knowledge for QA in science . they enrich the original corpus with relevant text snippets from an open-domain resource . the second method simply increases the amount of training data by appending additional in-domain instances. |
| Outcome: | The proposed methods achieve gains in accuracy of 8.1%, 13.0%, and 12.8% on science QA tasks. |
CoQAR: Question Rewriting on CoQA (2022.lrec-1)
Copied to clipboard
| Challenge: | Existing systems that ask questions in a conversational context may have contextual dependencies that make the understanding difficult. |
| Approach: | They propose to rewrite questions into an out-of-context form to facilitate understanding . they propose to use this form to train and evaluate conversational question answering models . |
| Outcome: | The proposed model can be used in the supervised learning of three tasks: question paraphrasing, question rewriting and conversational question answering. |
