In particular, Self-Attention has achieved significant results in NLP. However, it has been pointed out that although deep learning highly accurately classifies documents, it is difficult to interpret the basis of the decision. In this paper, we focus on the task of classifying news documents by their theme. We then propose methods for presenting the interpretability for classification decisions by deep learning. We first classify documents with LSTM Attention and show that this can classify documents with high accuracy. We second propose five methods for providing the basis of the decision by focusing on various values, e.g. Attention. Finally, we evaluate the methods and show that these methods can present interpretability.","subitem_description_type":"Other"}]},"item_4_biblio_info_10":{"attribute_name":"書誌情報","attribute_value_mlt":[{"bibliographicPageEnd":"7","bibliographic_titles":[{"bibliographic_title":"研究報告自然言語処理（NL）"}],"bibliographicPageStart":"1","bibliographicIssueDates":{"bibliographicIssueDate":"2021-07-20","bibliographicIssueDateType":"Issued"},"bibliographicIssueNumber":"1","bibliographicVolumeNumber":"2021-NL-249"}]},"relation_version_is_last":true,"weko_creator_id":"44499"},"id":212201,"updated":"2025-01-19T17:34:40.619222+00:00","links":{},"created":"2025-01-19T01:13:11.771595+00:00"}
