Reliability calculation device, the translation reliability calculation use method and a program for the translation engine

摘要

Without assuming statistical machine translation as a machine translation, and so that it is possible to prompt the appropriate translation result to the can to obtain a reliable and properly re-input to the input-side user if it was a low confidence to. For the input sentence, and the translation unit 501 to perform the machine translation for the translation result, the reverse translation means 502 to perform the inverse translation process, based on the distance between the input sentence and the reverse translation result, translation confidence and translation reliability calculation means 503 calculated to, input sentence, the translation results and at least one or more of the reverse translation result, the input sentence, reliability presentation to be presented to the user along with the reliability corresponding to the translation results or reverse translation result and means 504, reliability presenting means 504, the translation confidence in the case was less than the predetermined threshold, at least the input sentence or reverse translation result, the side of which have entered the first of the language with the translation reliability and characterized in that it is presented to the user.
