Due to the disaster, there were more than 200 dead and missing people. To minimize the damage in the event of such a large-scale disaster, it is important to collect and distribute information quickly and accurately. Therefore, the use of Twitter in the event of disasters has gotten much attention worldwide. The authors' research group is paying attention to utilizing Twitter at the time of disaster. For example, we have researched on the classification and mapping of tweets at the time of the Great East Japan Earthquake, and the implementation of a disaster-related information sharing system utilizing Twitter. The number of tweets explosively increases in large-scale disasters, therefore, it is important to analyze the characteristics of tweets for practical use of Twitter in the event of a disaster. In this paper, we report the analysis results of tweets posted in the 2018 Western Japan Heavy Rain Disaster.","subitem_description_type":"Other"}]},"item_4_biblio_info_10":{"attribute_name":"書誌情報","attribute_value_mlt":[{"bibliographicPageEnd":"7","bibliographic_titles":[{"bibliographic_title":"研究報告情報システムと社会環境(IS)"}],"bibliographicPageStart":"1","bibliographicIssueDates":{"bibliographicIssueDate":"2018-08-31","bibliographicIssueDateType":"Issued"},"bibliographicIssueNumber":"3","bibliographicVolumeNumber":"2018-IS-145"}]},"relation_version_is_last":true,"weko_creator_id":"11"},"id":191127,"updated":"2025-01-20T00:55:34.759674+00:00","links":{},"created":"2025-01-19T00:57:02.381205+00:00"}
