Copied to clipboard
| Challenge: | Evaluation metrics are a key ingredient for progress of text generation systems . a class of novel evaluation metrics based on BERT and its variants has been explored . |
| Approach: | They propose to disentangle BERT-based evaluation metrics along linguistic factors . they show they are sensitive to lexical overlap, just like BLEU and ROUGE . |
| Outcome: | The proposed metrics capture all aspects but are sensitive to lexical overlap, just like BLEU and ROUGE, the authors show . |
