METHOD FOR PROVIDING TRANSLATION INFORMATION, NON-TRANSITORY COMPUTER-READABLE RECORDING MEDIUM, AND TRANSLATION INFORMATION PROVIDING APPARATUS

A translation information providing apparatus includes a forward translator that generates a first translation by translating a first original sentence in a first language into a second language, a back translator that generates a first back translation by back-translating the first translation into the first language, and a translation result outputter that outputs at least either the first original sentence or the first translation and, as the first back translation, a back translation that semantically matches or is semantically similar to the first original sentence.
