面向航空手册的偏向性检索增强集成翻译模型

doi:10.11896/jsjkx.241100022

摘要/Abstract

摘要： 航空手册是指与大型民用飞机设计相关的出版物,包括飞行、维护、安全等手册。作为一种对语言表达的清晰度和精准度有极高要求的技术文档,航空手册的翻译要求译文符合简化技术英语规范(The Simplified Technical English Specification,STE)。简化技术英语是一种受控自然语言,对文档的语法和词汇使用提出了明确而严格的规则限制。为此,提出了一种STE引导的偏向性检索增强集成翻译模型(Biased Retrieval-augmented Ensembling Translation Model,BRAETM),模型内利用跨语言检索同类型且长度规范的偏向性目标语言序列指导解码端译文生成,同时采用STE Dictionary引导的规范词偏向性解码策略修正译文用词;模型外依据预估模块结果选择性集成非被动翻译模型,以此生成句式、语态、用词等方面更规范的译文。实验结果表明,提出的模型能够生成更符合简化技术英语规则的译文,相比先进的基线模型,在两个航空手册测试语料上的BLEU值分别提升了3.60和2.67。

Abstract: The aviation manuals refer to publications related to the design of large civil aircrafts,including flight manuals,maintenance manuals,and safety manuals.As a type of technical documentation that demands a high level of clarity and precision in language expression,the translation of aviation manuals requires adherence to the Simplified Technical English Specification(STE).STE is a controlled natural language that imposes explicit and stringent rules on the use of grammar and vocabulary in documentation.This paper proposes a biased retrieval-augmented ensembling translation model(BRAETM) for aviation manuals guided by STE.Within the model,biased target language sequences with the same sentence type and with lengths that meet the specification are cross-lingually retrieved to guide the translation generation at the decoder end,and a biased decoding strategy guided by the STE dictionary is adopted to correct the words in the translation.Outside the model,a non-passive translation model is selectively ensembled according to the estimation results of a prediction module,in order to generate more standardized translations in terms of sentence structure,voice and vocabulary.Experimental results show that the proposed model can generate translations that better adhere to the STE rules.Compared to the state-of-the-art baseline models,the BLEU scores of this model on two aviation manual test corpora are improved by 3.60 and 2.67,respectively.
