| Abstract(in English) | To minimize damage during disasters, the rapid collection and delivery of accurate information are essential. Because of this, the potentiality of social media, especially Twitter, in the case of a disaster has attracted worldwide attention. In this study, by extracting words representing areas (prefecture names and municipality names) from tweets posted during a large-scale disaster occurred in 201 in Japan (such as 2018 Osaka North Earthquake and 2018 Western Japan Heavy Rain Disaster), we analyze the attention areas (areas mentioned a lot in tweets). Moreover, we report the consideration results of the change of attention areas by time and disaster type by visualizing the analysis result on the map. |
