Evaluating the Factual Consistency of Abstractive Text Summarization (2020.emnlp-main)
Copied to clipboard
| Challenge: | a weakly-supervised approach is needed to verify factual consistency . auxiliary span extraction tasks are useful for verifying factual consistent summaries . |
| Approach: | They propose a weakly-supervised approach for verifying factual consistency . they transfer the model to summaries generated by several neural models . |
| Outcome: | The proposed approach outperforms models trained with strong supervision on source documents and human evaluations. |
