Machine translation apparatus and non-transitory computer readable medium

A technical term dictionary stores terms of a first language and each translated term of a second language. A translation memory stores source sentences of the first language and each target sentence of the second language. A translation unit translates a text of the first language into an output text of the second language by the technical term dictionary and the translation memory. A corresponding translation pair extraction unit extracts, from a source sentence matched with a sentence of the text and a target sentence corresponding to the source sentence stored in the translation memory, a corresponding translation pair comprising a word in the source sentence and a translated word corresponding to the word in the target sentence. An unmatch check unit checks whether the translated word does not match with a translated term corresponding to the word in the output text.
