| Challenge: | Existing models of robustness evaluation are incomprehensive, impractical, and invalid . |
| Approach: | They propose a framework for automatic robustness evaluation that shifts towards model-centric evaluation to further exploit the advantages of adversarial attacks. |
| Outcome: | The proposed framework is based on a model-centric evaluation protocol and a robustness evaluation protocol. |
Unsupervised Reference-Free Summary Quality Evaluation via Contrastive Learning (2020.emnlp-main)
Copied to clipboard
| Challenge: | Existing methods for document summarization consider the informativeness of the assessed summary and require human-generated references for each test summary. |
| Approach: | They propose to evaluate summary qualities without reference summaries by unsupervised contrastive learning. |
| Outcome: | The proposed method outperforms other evaluation metrics even without reference summaries. |
