Abstract:The research on bilingual corpora is one of t he most important topics in the field of natural language processing. Paragraph alignment is to find the translation paragraph pairs between source text and tar get text. Paragraph alignment is a necessary and important phase between section alignment and sentence alignment, but it is disregarded at present. This paper aims at dealing with this process. Because it is difficult and unnecessary to al ign paragraphs directly, this problem is changed into a “segmentation and align ment” one. This paper finds some anchors for segmentation first, and then match es the sentences which contain these anchors, finally checks the validity of the results and segments the texts into translation blocks. The experimental result s show that the method can achieve good results and can also be applied to other language pairs.
