A local SNS supports not only activities of the local society but is expected as a network infrastructure to support activities responding to disasters. Studies on SNSs are almost all based on network analysis or qualitative analysis. However, there have been no studies on text-mining for disaster recovery. The purpose of this study is to clarify the role of SNSs during disaster recovery by network and text-mining analysis.
