摘要/Abstract

摘要： 维吾尔语形态较为复杂，构形词缀在维吾尔语中占有重要地位，其语法与汉语有较大差别。针对维吾尔语的形态特点，分析汉语端到维吾尔语端在统计机器翻译中维吾尔语词缀的作用，搭建基于短语的汉维统计机器翻译系统，对词级粒度、词干级粒度、最大词干级粒度、词干-词缀级粒度、词干-词尾级粒度的汉维平行语料库进行对比实验，研究不同粒度的维吾尔语对汉维机器翻译中的词语对齐质量和语言模型质量的影响。实验结果表明，在上述5种粒度的维吾尔语语料中，基于词干的维吾尔语和基于词干-词尾的维吾尔语目标端语料的翻译质量明显提高。

关键词: 维吾尔语形态, 构形词缀, 词缀粒度, 统计机器翻译, 翻译质量

Abstract: The Uyghur morphology is comparatively complex and the configuration affix plays a significant role in Uyghur,which is grammatically very different from Chinese.Aiming at the morphology characteristics of Uyghur,this paper analyzes the function of Uyghur affix in statistical machine translation from Chinese to Uyghur.A phrase-based Chinese-Uyghur statistical translation system is built to conduct comparative experiments on Chinese-Uyghur parallel corpus with different levels of granularity,such as the word level granularity,the stem level granularity,the maximum stem level granularity,the stem-affix level granularity and the stem-suffix level granularity.Then the influence of Uyghur with different granularity on words alignment quality and language model quality in Chinese-Uyghur machine translation is studied.Experimental results show that the translation quality of the stem-based and the stem-suffix based Uyghur target corpus is significantly improved.

Key words: Uyghur morphology, configuration affix, affix granularity, statistical machine translation, translation quality
