摘要:

神经机器翻译(NMT)模型在大型双语数据集上是有效的。然而,现有的方法和技术表明,该模型的性能是高度依赖于训练数据的例子的数量。对于许多语言来说,拥有如此数量的语料库是一个遥不可及的梦想。从单语者探索新的语言使用双语词典的灵感,我们调查的双语词典的适用性语言极低,或没有双语语料库。在本文中,我们探讨了使用双语词典与NMT模型来改善极低资源语言的翻译的方法。我们将这项工作扩展到多语言系统,表现出zero-shot属性。我们详细分析了词典质量、训练数据集大小、语言家族等因素的影响,翻译质量。多个低资源测试语言的结果表明,我们的双语词典为基础的方法比基线的明显优势。

英文摘要:

Neural Machine Translation (NMT) models have been effective on large bilingual datasets. However, the existing methods and techniques show that the model's performance is highly dependent on the number of examples in training data. For many languages, having such an amount of corpora is a far-fetched dream. Taking inspiration from monolingual speakers exploring new languages using bilingual dictionaries, we investigate the applicability of bilingual dictionaries for languages with extremely low, or no bilingual corpus. In this paper, we explore methods using bilingual dictionaries with an NMT model to improve translations for extremely low resource languages. We extend this work to multilingual systems, exhibiting zero-shot properties. We present a detailed analysis of the effects of the quality of dictionaries, training dataset size, language family, etc., on the translation quality. Results on multiple low-resource test languages show a clear advantage of our bilingual dictionary-based method over the baselines.
