Balancing Global Quality and Pronoun-Specific Feedback for Context-Aware Machine Translation

Read the original on arXiv AI →

The paper introduces ProNMT, a reward-guided iterative self‑training approach that balances global translation quality with pronoun‑specific feedback for context‑aware machine translation. ProNMT samples candidate translations, scores them using reference‑free quality estimation and a pronoun label derived from references, and fine‑tunes on the highest‑scoring candidate. Experiments on English–German Europarl and English–French News Commentary show that ProNMT outperforms standard context‑aware fine‑tuning on BLEU and COMET, while ablations reveal that pronoun‑only feedback can harm overall quality and that confidence‑weighted feedback outperforms hard binary feedback.

Is Human Annotation Necessary? Iterative MBR Distillation for Error Span Detection in Machine Translation

The paper introduces Iterative MBR Distillation for Error Span Detection (ESD) in machine translation, a self‑evolution framework that replaces human annotations with pseudo‑labels generated by a large language model. By iteratively applying Minimum Bayes Risk decoding, the method produces high‑quality error spans without costly human effort. Experiments on WMT Metrics Shared Task datasets show that models trained solely on these pseudo‑labels outperform both unadapted baselines and supervised models trained on human data at system and span levels, while keeping sentence‑level performance competitive.

Discourse Dependency: A Continuous Criterion for Translation Difficulty

The paper introduces discourse dependency (DDP) as a continuous measure of translation difficulty based on how far back a segment must look to resolve references. DDP is computed from named entity re‑mentions and pronominal coreference, and is validated against gold coreference with high reliability. Applying DDP to recent WMT benchmarks reveals a bias toward low‑DDP segments, and experiments show that as DDP increases, no current context‑injection strategy matches human post‑editing quality.
