基于译文的英汉双语句子自动对齐

本文利用英汉互译译文间的内在联系，提出了基于译文的方法，通过使用一部翻译较完整的词典作为桥梁，将英汉句子间的对应关系连结起来，根据英语文本中的单词，在词典中找其对应的译文，并以译文到汉语句子中去匹配，根据评价函数和动态规划算法找到对齐句对，实验结果证明这种对齐方法消除了基于长度做法中错误蔓延的情况。并且普遍适用于任何文本，它大大地提高了对齐的精度，其效果是令人满意的。

TRANSLATION-BASED AUTOMATIC ALIGNMENT OF ENGLISH AND CHINESE PARALLEL CORPORA

This paper utilizes the potential co relations between translation and proposes a method basing on translation. With a dictionary as the bridge, the corresponding relations between the translation are linked. The corresponding translation of the words in English text are found in the dictionary and then matched with the translation of Chinese text. The alignment sentences are determined according to an evaluating function and the dynamic programming algorithm. The experimental result shows that this new method greatly improves the precision of sentence alignment.
