中文摘要：

双语语料库建设及其自动对齐研究对计算语言学的发展具有重要的意义。目前国内外已建立了各类汉英双语语料库以及服务于汉英机器翻译的双语对齐语料库和短语库。为了少数民族语言的机器翻译的研究从一开始就从较高起点起步,需要对汉藏双语文本的篇章级、段落级、句子级自动对齐技术进行研究,为开发和研究汉藏机器翻译奠定基础。主要研究汉藏双语语料库对齐、汉藏双语词典抽取、双语语料的收集、整理、存储以及检索等关键技术。最终研究结果是藏文编码的自动识别与转换技术,藏语语料库构建技术、汉藏双语词典抽取技术、汉藏平行语料库句子和词语对齐技术,并建立面向汉藏机器翻译的大规模汉藏双语对齐语料库。

英文摘要：

The costruction of bilingual Corpus and its automatic alignment research are of vital importance for the development of the computational linguistics.So far various types of Chinese-English bilingual corpus,including substantial sentnece aligned corpus for MT,have been developed both in China and abroad.In order to start the MT research involving minority with the state-of-arts technology,the research on the automatic alignments at the discourse level,paragraph level and sentence level between the Chinese and Tibetan vi-texts are necessary.This paper introduces a project on the Sino-Tibetanbilingual corpus alignments,the Chinese-Tibetan bilingual dictionary extraction,and the key technologies in the corpus collection,storage and retrieval.The project has accomplished such technologies as the Tibetan coding identification and conversion,th Tibetan corpus construction,the Sino-Tibetan bilingual dictionary extraction,the Sino-Tibetan sentence alignment and word alignments,and finally achieving a large-scale aligned Sino-Tibetan bilingual corpus for Chinese-Tibetan machine translation.
