| Abstract(in English) | In the event of a large-scale disaster, prompt and accurate information gathering and dissemination is critical to minimize damage. Against this background, the social media platform Twitter is expected to be utilized because of its high immediacy and large number of users. In this study, we focused on tweets posted in July 2022, when record-setting short-time heavy rainfall information was announced in various regions of Japan, and analyzed them by extracting keywords in time series and visualizing their co-occurrence networks. In addition, we report the analysis results from a qualitative perspective by tabulating the retweeted images. |
