learning, in which a phrase extraction such as key phrase extraction and named entity extraction is chosen for a sub-task, has shown improvements for the accuracy of text classification. However, multi-task learning requires extra annotations for sub-tasks in addition to the annotation for the mainstream text classification task. That extra annotation incurs extra human and financial costs, which are typically not small. These costs are therefore a barrier to the practical application of multi-task learning. To deal with this issue, the authors conducted research on realizing sub-tasks by automatic labeling for sub-tasks using a heuristic method, and confirmed that it improved classification accuracy. Although the previous findings can be widely applicable to other heuristic-based labeling methods to create sub-tasks, their availability has not been discussed. In addition, the requirements that such sub-tasks should satisfy have not been revealed. Therefore, this study attemps to clarify the requirements for improving the accuracy of text classification by using generic subtasks in multi-task learning.","subitem_description_type":"Other"}]},"item_4_biblio_info_10":{"attribute_name":"書誌情報","attribute_value_mlt":[{"bibliographicPageEnd":"6","bibliographic_titles":[{"bibliographic_title":"研究報告自然言語処理（NL）"}],"bibliographicPageStart":"1","bibliographicIssueDates":{"bibliographicIssueDate":"2023-03-11","bibliographicIssueDateType":"Issued"},"bibliographicIssueNumber":"12","bibliographicVolumeNumber":"2023-NL-255"}]},"relation_version_is_last":true,"weko_creator_id":"44499"}}
