Papers with answer-explanation coupling
F1 is Not Enough! Models and Evaluation Towards User-Centered Explainable Question Answering (2020.emnlp-main)
Copied to clipboard
| Challenge: | Existing models and evaluation settings have shortcomings regarding the coupling of answer and explanation which might cause serious issues in user experience. |
| Approach: | They propose a hierarchical model and a new regularization term to strengthen the coupling of answer and explanation and two evaluation scores to quantify the couple. |
| Outcome: | The proposed model strengthens the answer-explanation coupling and provides evaluation scores that align with user experience. |
