In this paper, first, we describe the construction of the previous system and its problems. Second, we describe how DISAANA solves them by focusing on modality analysis, which prevents the extraction of incorrect answer candidates. We evaluated the question answering performance of the tweets posted during the 2011 Great East Japan Earthquake using 192 manually constructed questions and their answers. DISAANA achieved a 63.0 F-measure, which outperformed the previous system's 56.0 score. We discuss further directions based on error analysis and report the results of demonstration experiments of DISAANA for a local government context.","subitem_description_type":"Other"}]},"item_3_biblio_info_10":{"attribute_name":"書誌情報","attribute_value_mlt":[{"bibliographicPageEnd":"120","bibliographic_titles":[{"bibliographic_title":"情報処理学会論文誌コンシューマ・デバイス＆システム（CDS）"}],"bibliographicPageStart":"106","bibliographicIssueDates":{"bibliographicIssueDate":"2016-05-24","bibliographicIssueDateType":"Issued"},"bibliographicIssueNumber":"1","bibliographicVolumeNumber":"6"}]},"relation_version_is_last":true,"weko_creator_id":"11"},"created":"2025-01-19T00:34:34.527040+00:00","id":162234,"links":{}}
