PROBLEM TO BE SOLVED: To realize a device, a method and a program for applying translation probability, by which words in a first language can be highly accurately made correspondent to second words by using a sentence example in the first language and a sentence example in the second language, which are not in a translation relation mutually. SOLUTION: This translation probability applying device is characterized in that it has a first language/language corresponding to words in the first language as word correspondence couples, a translation probability model for estimating a statistic quantity concerning the appearance of a word in the second language from a statistic quantity found by a first language statistic quantity calculation module from a sentence example collection in the first language while using a translation probability applied to each of word correspondence couples on the translation dictionary as a parameter and a translation probability applying part for finding a parameter so that a difference between the statistic quantity found by the second language statistic quantity calculation module from the sentence example collection in the second language and the statistic quantity in the second language estimated from the first language by the translation probability model can be minimized. |
