TRANSLITERATION MODEL GENERATION DEVICE, TRANSLITERATION APPARATUS, AND COMPUTER PROGRAM THEREFOR

摘要

PPROBLEM TO BE SOLVED: To provide a transliteration apparatus for generating a transliteration model in accordance with the actual use to transliterate a word between languages with high reliability using the transliteration model. PSOLUTION: The transliteration apparatus 20 includes: a transliteration pair storage apparatus 30 for storing a transliteration pair for a word in first and second languages; a transliteration model generation part 44 for associating characters or character strings constituting a word or a word string in the first and second languages for each transliteration pair, generating a transliteration model 48 in which each of the associated pair of characters in the first and second languages are defined as translated word for the other word, and outputting it as a transliteration model; a language model generation part 46 for generating an N-gram language model 50 by the character units in the second language; and an automatic translation apparatus 54 for transliterating a word 52 input in the first language to a word 56 in the second language to be output by a statistical automatic translation using the translation model 48 and the language model 50.
