To enhance accuracy of machine translation, to obtain a translated document with high translation accuracy, and to faithfully translate a document to be translated.SOLUTION: A document to be translated is translated by using a neural network to generate a first translated document. A modification-target word or phrase is determined from words and phrases contained in the document to be translated on the basis of an analysis result for the first translated document. The modification-target word or phrase is replaced with a high frequency word in learning data used for learning in the neural network to modify the document to be translated. And the modified document to be translated is translated by using the neural network to generate a second translated document.SELECTED DRAWING: Figure 1 【課題】機械翻訳の精度を高める。翻訳精度の高い翻訳文書を得る。被翻訳文書に対して忠実に翻訳する。【解決手段】ニューラルネットワークを用いて被翻訳文書を翻訳することで、第１の翻訳文書を生成し、第１の翻訳文書の解析結果に基づき、被翻訳文書に含まれる語句の中から、修正対象語句を決定し、修正対象語句を、ニューラルネットワークの学習に用いた学習データにおける高頻度語に置き換えることで、被翻訳文書を修正し、ニューラルネットワークを用いて修正後の被翻訳文書を翻訳することで、第２の翻訳文書を生成する。【選択図】図１
