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. |

| Challenge: | Existing methods for judging metrics are sensitive to the translations used for evaluation, leading to falsely confident conclusions about a metric’s efficacy. |
| Approach: | They propose a method for thresholding performance improvement under an automatic metric against human judgements by using a pairwise system ranking method. |
| Outcome: | The proposed method allows quantification of type I versus type II errors incurred, i.e., insignificant human differences in system quality that are accepted, and significant human differences that are rejected. |

Revisiting Context Choices for Context-aware Machine Translation (2024.lrec-main)
Copied to clipboard
| Challenge: | Recent work has cast doubt on whether context-aware machine translation models learn useful signals from context or are improvements in automatic evaluation metrics just a side-effect. |
| Approach: | They propose to use separate encoders for source sentence and context as multiple sources for one target sentence to train context-aware machine translation models. |
| Outcome: | The proposed model improves translation quality even with empty lines as context, but the correct context improves it and random out-of-domain context degrades it. |
