Putting Evaluation in Context: Contextual Embeddings Improve Machine Translation Evaluation (P19-1)
Copied to clipboard
| Challenge: | Existing evaluation metrics are limited and can be easily portable to new languages. |
| Approach: | They propose a simple unsupervised metric and additional supervised metrics which rely on contextual word embeddings to encode the translation and reference sentences. |
| Outcome: | The proposed model outperforms existing metrics on the WMT 2017 dataset and is more accurate than existing models. |
