摘要

Frequent and heavy rainfall in recent years has result into spontaneous damage in Japan. In this paper, we analyzed the open-ended answer text data of questionnaire survey from the municipal government officials who had experienced evacuation advisory or order publishing among heavy rain disasters in 2009. We applied a text mining system (TRENDREADER) to analyze the text data. The characteristics of these extracted learnt lessons and found issues suggest that, the local responders in heavy rainfall regions should reinforce their emergency response, decision-making of evacuation advisory and communication to the residents.
