no. 1 Embodiment approach
[0030] refer to figure 1 The machine translation device of the first embodiment will be described.
[0031] The machine translation device 100 of the first embodiment includes an acquisition unit 101, a translation unit 102, a translation candidate acquisition unit 103, a fluency calculation unit 104, a reverse translation unit 105, a similarity calculation unit 106, a translation selection unit 107, and an output unit. 108 . The translation dictionary database 109 , the fluency database 110 and the similarity database 111 .
[0032] The acquisition unit 101 acquires the original text in the first language to be translated from the outside. The original text can be obtained by various methods of receiving input from the user that are generally used, such as a keyboard, a pointing device, handwritten character recognition, OCR, and voice recognition. Alternatively, regardless of the user's input, it may be set so that original texts are acquired sequentially from the outside....
no. 2 Embodiment approach
[0089] In the first embodiment, words included in the translation dictionary are used as translated word candidates. However, in the second embodiment, the translated word candidates are also acquired from the fluency database. In this way, it is possible to select translation word candidates that also take into account the fluency of the translation in the second language, and generate a more natural translation.
[0090] refer to Figure 13 The block diagram of the figure shows the machine translation device of the second embodiment.
[0091] The machine translation device 1300 of the second embodiment includes: an acquisition unit 101, a translation unit 102, a translation candidate acquisition unit 1301, a fluency calculation unit 104, a reverse translation unit 105, a similarity calculation unit 106, a translation selection unit 107, an output unit 108 , translation dictionary database 109 , fluency database 110 and similarity database 111 .

Abstract
The invention provides a machine translation apparatus, a method and a program. The machine translation apparatus includes a translation unit for translating an original text of a first language into a translated text of a second language; a translated word candidate acquisition unit for acquiring more than one second translated word different from the first translated word for an original word in the original text corresponding to the first translated word in the translated text, and taking the first translated word and the second translated word as translated word candidates; a fluency calculating unit for calculating the fluency of the translated word candidates, wherein the fluency represents the suitability of the translated word candidates when the candidates are inserted into the insertion position of the first translated word in the translated text to generate a natural translated text; a reverse translation unit for obtaining more than one reverse-translated word for each of the translated word candidates by reverse-translating each translated word candidate into the first language; a similarity calculating unit for calculating the semantic similarity of the reverse-translated words to the original words in the first language; and a translated word selection unit for selecting a corrected translated word to be replaced with the first translated word from among the translated word candidates based on the similarity and fluency.
Description
technical field [0001] Embodiments of the present invention relate to a machine translation device, method, and program for translating a first language into a second language. Background technique [0002] In recent years, with the improvement of computer performance and the rapid spread of broadband infrastructure, a large number of machine translation devices and machine translation services that translate original texts in a first language into translations in a second language have become popular. Generally speaking, in machine translation, a plurality of translated word candidates in the second language are held in units of words in the first language and sections of the first original word. In such machine translation, it is important to select an appropriate translation word in consideration of the identity of meaning between the sentence on the source text side and the sentence on the translation side and the fluency of the translation, based on the input original t...
