Embodiment Construction

[0027] Exemplary embodiments of the machine translation apparatus and method according to the present invention will be described in detail below with reference to the accompanying drawings. In the following, translation between Japanese and English will be used as an example, but the language to be translated is not limited to these two languages, and any language can be the target.

[0028] A machine translation apparatus according to an embodiment of the present invention narrows down translation candidates obtained by an example-based translation system by referring to translation results obtained by a rule-based translation system.

[0029] As shown in FIG. 1 , the machine translation device 100 includes an example storage unit 120, a receiving unit 101, an example translation unit 102, a translation word candidate generation unit 103, a translation word candidate addition unit 104, a candidate evaluation unit 105, and an output control unit 106.

[0030] The example stor...

Abstract

A receiving unit receives an input sentence in a source language. An example translation candidate translated from the input sentence into a target sentence and a first likelihood of the example translation candidate are obtained. A generating unit translates the input sentence into the target language by a process different from a process of an example translating unit, and among candidates for a translation result with each word in the input sentence, generates a translation word candidate showing a candidate whose second likelihood is equal to or more than a first threshold value. When a translation word included in the example translation candidate is not included in the translation word candidate, a changing unit lowers the first likelihood by only a predetermined value. A selecting unit selects the example translation candidate whose first likelihood is a maximum, from the example translation candidate.

Description

technical field [0001] The present invention relates to an apparatus and method for translating a sentence in a source language into a sentence in a target language by combining multiple translation systems including a translation system that performs translation by referring to similar translation examples. Background technique [0002] As a translation system in a machine translation device in the related art that converts a source language sentence expressed in a first language into a second language for output, there are known a rule-based translation system, a statistical-based translation system, and an example-based translation system. translation system, etc. [0003] A rule-based translation system is a translation system that uses rules to give a translation method with conditions such as words forming a source language sentence, grammatical structure and semantic interpretation of the source language sentence. A statistics-based translation system is a translatio...
