Machine Translation Using Semantically Classified Expression Structure Pattern Pairs

认识到语义类型学“对象识别的方式体现在语言表达的结构中”的思想，我们研究了通过对源语和目的语表达的语义分类来吸收语言之间识别差异的机器翻译方法。研究结果如下：(1)利用N-gram统计技术，开发了从大规模日英翻译样本中自动提取复杂、复合和特殊结构句的日英表达结构模式的方法。(2)设计了描述日英表达结构模式的脚本语言，并对其模式描述进行了检验。(3)设计描述语义类型学的元语言，并对其语义类型学表达能力进行检验。(4)基于ATN技术，设计了一种快速匹配给定日语/英语表达与大规模日语/英语结构模式的方法。(5)构建了复杂、复合、特殊结构句的日英表达结构模式对。(1)研究了利用现有的简单句的日英表达结构模式对、简单句的日英表达结构模式对以及语义分类的复杂句、复合句和特殊结构句的日英表达结构模式对进行翻译的日英机器翻译方法的机制。(2)通过对日英机器翻译系统进行原型设计，验证了该方法作为机器翻译方法的可行性和有效性。

Recognizing the thoughts of semantic typology that "the way of object recognition is reflected in the structure of linguistic expression", we research machine translation method that absorbs the differences in recognition between languages through the semantic classification of expressions of source language and target language.The results of research are as follows.1.Research and building of semantically classified Japanese-English structure pattern pairs(1)Using the technique of N-gram statistics, we developed methods to automatically extract Japanese-English expression structure patterns of complex, compound, and special structure sentences from large scale Japanese-English translation samples.(2)We designed the script language for describing Japanese-English expression structure patters and we checked its description of patterns.(3)We designed the meta-languages for describing the semantic typology and we checked its semantically typological expression capability.(4)Based on the technique of ATN, we designed the method to match between the given Japanese/English expressions and the large scale Japanese/English structure patterns with high speed.(5)We built Japanese-English expression structure pattern pairs of complex, compound, and special structure sentences.2.Research and prototyping Japanese-English Machine translation system(1)We have researched the mechanism of Japanese-English machine translation methods that translate by applying the existing Japanese-English expression structure pattern pairs of simple the existing Japanese-English expression structure pattern pairs of simple sentences and semantically classified Japanese-English expression structure pattern pairs of complex, compound, and special structure sentences.(2)We verified the possibility and effectiveness as the machine translation methods by prototyping Japanese-English Machine translation system.
