摘要:

质量评估的目的是在没有参考译文的情况下衡量翻译内容的质量。这对于需要高质量翻译的现实场景中的机器翻译系统至关重要。虽然存在许多用于质量估计的方法,但它们基于需要昂贵的人工标记数据的监督机器学习。作为一种替代方案,我们提出了一种技术,不依赖于人类注释的例子,而是使用合成的训练数据。我们在合成数据上训练了用于监督质量估计的现成架构,并表明所产生的模型在句子和单词级预测方面都实现了与在人类注释数据上训练的模型相当的性能。

英文摘要:

Quality estimation aims to measure the quality of translated content without access to a reference translation. This is crucial for machine translation systems in real-world scenarios where high-quality translation is needed. While many approaches exist for quality estimation, they are based on supervised machine learning requiring costly human labelled data. As an alternative, we propose a technique that does not rely on examples from human-annotators and instead uses synthetic training data. We train off-the-shelf architectures for supervised quality estimation on our synthetic data and show that the resulting models achieve comparable performance to models trained on human-annotated data, both for sentence and word-level prediction.
