To provide a learning method capable of suppressing learning of models that generate less readable summary.SOLUTION: The learning method of machine learning of a model that generates a summary from an input sentence, causes a computer to execute a series of processing including: acquiring an input sentence and a correct summary; generating a pseudo sentence in which a non-grammatical expression is simulated by changing the word order of the words included in the correct summary; and updating model parameters on the basis of the probability of generation of a pseudo sentence from the input sentence by model and the probability of generation of a correct summary by the model from the input sentence.SELECTED DRAWING: Figure 1 【課題】可読性が低い要約文を生成するモデルが学習されるのを抑制すること。【解決手段】入力文から要約文を生成するモデルの機械学習を行う学習方法において、入力文および正解の要約文を取得し、正解の要約文に含まれる単語の語順を入れ替えることにより非文法的な表現が擬似的に再現された擬似文を生成し、モデルによって擬似文が入力文から生成される擬似文の生成確率、および、モデルによって正解の要約文が入力文から生成される正解の要約文の生成確率に基づいてモデルのパラメータを更新する、処理をコンピュータが実行する。【選択図】図１
