اكتسبت الترجمة الآلية المتزامنة الجر مؤخرا، بفضل تحسينات الجودة المهمة ومختام تطبيقات البث.تحتاج أنظمة الترجمة المتزامنة إلى إيجاد مفاضلة بين جودة الترجمة ووقت الاستجابة، وبالتالي تم اقتراح تدابير الكمون المتعددة.ومع ذلك، يتم تقدير تقييمات الكمون للترجمة الفورية على مستوى الجملة، ولا تأخذ في الاعتبار الطبيعة المتسلسلة لسيناريو البث.في الواقع، هذه تدابير الكمون على مستوى الجملة ليست مناسبة تماما للترجمة المستمرة، مما أدى إلى وجود أرقام غير متماسكة مع سياسة الترجمة المتزامنة للنظام التي يتم تقييمها.يقترح هذا العمل تكيف مستوى دفق من تدابير الكمون الحالية بناء على نهج إعادة تجزئة مطبق على ترجمة الناتج، والتي يتم تقييمها بنجاح على شروط البث لمهمة الإشارة IWSLT.
Simultaneous machine translation has recently gained traction thanks to significant quality improvements and the advent of streaming applications. Simultaneous translation systems need to find a trade-off between translation quality and response time, and with this purpose multiple latency measures have been proposed. However, latency evaluations for simultaneous translation are estimated at the sentence level, not taking into account the sequential nature of a streaming scenario. Indeed, these sentence-level latency measures are not well suited for continuous stream translation, resulting in figures that are not coherent with the simultaneous translation policy of the system being assessed. This work proposes a stream level adaptation of the current latency measures based on a re-segmentation approach applied to the output translation, that is successfully evaluated on streaming conditions for a reference IWSLT task.

We propose a generative framework for simultaneous machine translation. Conventional approaches use a fixed number of source words to translate or learn dynamic policies for the number of source words by reinforcement learning. Here we formulate simu
Reference-free evaluation has the potential to make machine translation evaluation substantially more scalable, allowing us to pivot easily to new languages or domains. It has been recently shown that the probabilities given by a large, multilingual
Recently a number of approaches have been proposed to improve translation performance for document-level neural machine translation (NMT). However, few are focusing on the subject of lexical translation consistency. In this paper we apply one transla
Most existing simultaneous machine translation (SiMT) systems are trained and evaluated on offline translation corpora. We argue that SiMT systems should be trained and tested on real interpretation data. To illustrate this argument, we propose an in
Neural machine translation (NMT) is sensitive to domain shift. In this paper, we address this problem in an active learning setting where we can spend a given budget on translating in-domain data, and gradually fine-tune a pre-trained out-of-domain N
