Shortcomings of Question Answering Based Factuality Frameworks for Error Localization (2023.eacl-main)
Copied to clipboard
| Challenge: | Abstractive summarization systems often generate summaries with factual errors . many approaches to detect these errors have been proposed, but this capability has not been evaluated in past research . |
| Approach: | They propose to use question answering-based factuality metrics to detect errors in summaries . they find that QA-based frameworks fail to correctly identify error spans in generated summary . |
| Outcome: | The proposed methods outperform trivial exact match baselines in localizing errors in summaries. |

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. |
