KPQA: A Metric for Generative Question Answering Using Keyphrase Weights (2021.naacl-main)
Copied to clipboard
| Challenge: | Existing n-gram similarity metrics fail to discriminate the incorrect answers due to the free-form of the answer. |
| Approach: | They propose a new metric that assigns different weights to each token via keyphrase prediction to judge the correctness of GenQA. |
| Outcome: | The proposed metric has a significantly higher correlation with human judgments than existing metrics in various datasets. |

| Challenge: | Prior work has shown that models may exploit shortcuts that are difficult to detect using standard n-gram similarity metrics such as ROUGE. |
| Approach: | They propose to use human-assessed summary quality facets and pairwise preferences to improve MDS evaluation methods. |
| Outcome: | The proposed methods improve the quality of literature review summarization models . they use human-assessed summary quality facets and pairwise preferences . |
