MACHINE TRANSLATION DEVICE, COMPUTER PROGRAM, AND COMPUTER

摘要

PROBLEM TO BE SOLVED: To provide a statistical machine translation device capable of performing machine translation with high precision between greatly different languages.

SOLUTION: This machine translation device 80 is provided with a chunk translation part 90 and a chunk rearrangement processing part 92. The chunk translation part 90 receives an input sentence 78 and outputs a plurality of chunk lines with high possibility from translated chunk lines obtained for optional chunk divisions of the input sentence by using a dictionary stored in a dictionary storage part 84 and a translation model stored in a translation model storage part 74. The chunk rearrangement processing part 92 rearranges chunks of each of the output chunk lines outputted from the chunk translation part 90 and outputs the arrangement of the chunks with the highest likelihood, which is computed according to the translation model stored in the translation model storage part 74 and a chunk pair appearance frequency stored in a chunk pair storage part 76, as a translated sentence 82.
