汉—蒙机器翻译中源语言动词短语的转换及消歧方法

Conversion and Disambiguation of Verb Phrases in the Source Language in Chinese-Mongolian Machine Translation

本文以《汉蒙机器翻译系统》为对象,基于规则的机器翻译方法为例,阐述了从汉语动词短语,主要是附加式结构动词短语、祈使式动词短语、联合结构动词短语、述补结构动词短语、述宾结构动词短语、状中结构动词短语等六种短语,向蒙古语转换中的对应关系。研究表明,它们之间的对应关系不是一对一的关系,而是一对多的关系。所以对蒙古语短语的转换时采用了内部结构消岐法、原型消岐法、限定法和局部规则法等四种消岐方法。

Taking the regular machine translation methods as an example,the author studies the Chinese-Mongolian Machine Translation System and elaborates the corresponding relationship between Chinese verb phrases and Mongolian verb phrases（mainly additive verb phrases,imperative verb phrases,verb phrases in combined structure,verb phrases in predicate-complement structure,those in predicate-object structure or in adverbial-verb structure）.It shows that there is not a one-to-one,but one-to-multiple relationship between them.Therefore,the translation of mongolian phrases generally makes use of the following methods to eliminate ambiguities： inner structure disambiguation,prototype disambiguation,restriction and partiality.
