Summary:To recognize whether or not contents of a plurality of summaries have consistency in a learner which outputs the plurality of summaries from an input text in line with mutually different policies.SOLUTION: A plurality of output units 30 included in a learner 20 output a plurality of summaries from an input text T in line with mutually different policies. When outputting the summary, each of the output units 30 generates an attention map AM where a weight αi,j of each input word WIi included in the input text T, for each output word WOj included in the summary are set. The weight αi,j shows the degree of importance of each of the input words WIi when the output unit 30 outputs the summary. A consistency calculation unit 36 calculates an importance vector EV which shows the degree of importance of each of the input words WIi when the summary is output, on the basis of the attention map AM relating to each of the summaries, and calculates the degree of difference between the importance vectors EV corresponding to the respective summaries.SELECTED DRAWING: Figure 3 【課題】入力文章から互いに異なる方針に沿って複数の要旨を出力する学習器において、複数の要旨の内容が一貫性を有するものであるか否かを把握可能とする。【解決手段】学習器20に含まれる複数の出力部30は、互いに異なる方針に沿って、入力文章Tから複数の要旨を出力する。各出力部30は、要旨を出力するにあたり、要旨に含まれる各出力単語WOjに対する、入力文章Tに含まれる各入力単語WIiの重みαi,jが設定されたアテンションマップAMを生成する。重みαi,jは、出力部30が要旨を出力する際に各入力単語WIiを重要視する度合いを示すものである。一貫性演算部36は、各要旨に関するアテンションマップAMに基づいて、各要旨を出力した際の各入力単語WIiの重要度を示す重要度ベクトルEVを演算し、各要旨に対応する各重要度ベクトルEV間の相違度を演算する。【選択図】図3
