摘　　要：盲文转换技术可以推进盲人群体的信息无障碍化进程,有着相当的重要性.随着信息全球化发展,盲人不可避免地接触到包含中英双语的信息.现有中英盲文转换系统能较好完成中英文字符到盲文的转换,但是对标点的转换效果不佳,表现为对一符多用情况区分效果不好、未对中英标点混用情况进行纠错两方面.若未能恰当处理一符多用及中英标点混用情况,很可能会对盲人阅读造成影响甚至误解.本文详细分析以上问题,设计并实现一种具有标点区分和纠错能力的中英盲文转换系统.基于BCC语料库构建测试语料,对该系统开展一系列测试和评估.实验结果表明,与其他类型转换系统相比,本系统能够结合语言类型和上下文结构,有效区分标点转换中的一符多用情况,并能纠正中英标点混用问题,对我国信息无障碍化进程起到促进作用.Braille conversion technology is crucial for advancing information accessibility for the blind.With the rapid advancement of information globalization,the blind are increasingly exposed to bilingual information in both Chinese and English.While existing braille conversion systems have successfully translated Chinese and English into braille,they fall short in accurately converting punctuation,including poor differentiation of punctuation with multiple uses and lack of error correction for the mixed use of Chinese and English punctuation.Failure to address these issues may lead to misunderstanding of text by the blind.This study delves into these problems,designing and implementing a bilingual braille conversion system capable of distinguishing multipurpose punctuation and correcting the mixed use of punctuation.The performance of the system is evaluated by using a dataset based on BLCU Chinese Corpus.The results demonstrate that the proposed system accurately distinguishes multipurpose punctuation and corrects the mixed use of Chinese and English punctuation according to language types and context,outperforming other braille conversion systems.Overall,this research has significant potential for promoting information accessibility in China.
