摘　　要：探讨汉英句级对齐软件设计中两项主要技术,即哈希算法与词典语义映射在对齐中的运用。哈希算法能帮助软件从词典大量的英汉词条语义信息中快速提取所需的对应义,结合语义映射,将需要对齐的句子关键词信息进行语义识别,从而有效提高汉英句子对齐效果。Automatic sentential alignment of Chinese and English texts is of critical importance to formulate Chinese-English parallel corpora.The alignment quality has direct impact on the reliability of related research such as machine translation,bilingual lexicography and contrastive language stud-ies.This research adopts the two key technologies of alighment software designing,i.e.hash algo-rithm and semantic mapping to perform sentential alignment of Chinese /English texts.hash algo-rithms enable retrieving information from the knowledge database in a high speed,and can conduct semantic recognition of the key words/information of the sentences to be aligned via semantic map-ping to attain effective E-C corpora alignment.This research can shed new light on Chinese /English sentential alignment.
