Evaluating Question Answering Evaluation (D19-58)
Copied to clipboard
| Challenge: | Existing n-gram based QA metrics have a number of drawbacks and are not suitable for all extractive tasks. |
| Approach: | They propose to use BERTScore to evaluate translation for question answering (QA) they also explore whether existing n-gram based metrics are suitable for generative QA . |
| Outcome: | The proposed BERTScore metric fails to provide stronger correlation with human judgements . |
Addressing Semantic Drift in Generative Question Answering with Auxiliary Extraction (2021.acl-short)
Copied to clipboard
| Challenge: | Recent work focuses on question answering based on machine reading comprehension . current approaches treat QA as extracting a consecutive piece of text to a given question. |
| Approach: | They propose a generative QA model that incorporates an extractive mechanism into a model. |
| Outcome: | The proposed model improves quality and semantic accuracy over baseline models. |
