| Challenge: | Existing methods for question answering system lack large-scale question matching corpora . lack of large-sized question matching results in problem solving . |
| Approach: | They propose a large-scale Chinese question matching corpus which is released to the public . they use a search engine to collect large-sized question pairs related to high-frequency words . |
| Outcome: | The proposed corpus is more general than paraphrase corpus as it focuses on intent matching rather than paraphrasing. |

Knowledge Corpus Error in Question Answering (2023.findings-emnlp)
Copied to clipboard
| Challenge: | Recent work in open-domain question answering (QA) has explored generating context passages from large language models (LLMs) however, it is not well understood why generated passages can be more effective than retrieved ones. |
| Approach: | They propose to generate context passages from large language models by paraphrasing human-annotated gold context using LLMs to observe knowledge corpus error. |
| Outcome: | The proposed framework shows that paraphrasing human-annotated gold contexts improves performance over retrieval steps. |
