摘要
作为目前主流翻译方法的神经网络机器翻译已经取得了很大突破,在很多具有丰富数据资源的语言上的翻译质量也不断得到改善,但对于稀缺资源语言的翻译效果却仍然并不理想.稀缺资源语言机器翻译是目前机器翻译领域的重要研究热点之一,近几年来吸引了国内外的广泛关注.本文对稀缺资源语言机器翻译的研究进行比较全面的回顾,首先简要介绍了与稀缺资源语言翻译相关的学术活动和数据集,然后重点梳理了目前主要的研究方法和一些研究结论,总结了每类方法的特点,在此基础上总结了不同方法之间的关系并分析了目前的研究现状.最后,对稀缺资源语言机器翻译未来可能的研究趋势和发展方向进行了展望,并给出了相关建议.
As the mainstream approach in the field of machine translation,neural machine translation(NMT)has achieved great improvements on many rich-source languages,but performance of NMT for low-resource languages ae not very good yet.Low-resource NMT has been one of the most popular issues in MT and attracted wide attention around the world in recent years.This paper presents a survey on low-resource NMT research.We first introduce some related academic activities and feasible data sets for the translation,then categorize and summarize several types of approaches mainly used in low-resource NMT in detail,and present their features,as well as relations between them,and describe the current research status.Finally,we propose some advices on possible research trends and directions of this field in the future.
