Method and device for machine translation

The invention discloses a machine translation method and a machine translation device, related to the field of natural language processing. The device includes: a source language input unit, which inputs source language sentences; a source language analysis unit, which analyses the morphology and syntax to acquire the syntactic structure, and sets property features for the nodes of the syntactic structure; a storage unit of any-genitive determination model, which saves the any-genitive determination model; a determination unit of any-genitive, which determines whether the sentence contains any-genitive; an extraction unit of any-genitive phrases, which obtains any-genitive phrases; a translation unit of any-genitive phrases, which translates any-genitive phrases; a first extraction unit, which obtains the remaining part of the source language sentence; a machine translation unit, which translates the remaining part of the source language sentence; an integration unit of translation results, which integrates the translation results to obtain a target language; a target language output unit, which outputs the target language. The invention can decrease the complexity of the source language syntactic structure, and improve the generation efficiency of the target language, thus improving translation accuracy, and appropriately decreasing decoding computation of machine translation.
