Outline of Final Research Achievements |
In this study, the author developed a method in which the descriptions of damage scenarios are collected from over a thousand people and the damage costs evaluated by examining the frequency of used words. Specifically, a questionnaire survey was first conducted to extract the people's views of disaster, and the frequencies of specific words used in these descriptions of disaster were used as indicators of damage. It was then assumed that the difference in the appearance of these words in newspaper articles before and after an actual disaster represents the damage impact, and this difference was used to estimate the damage costs. The results suggested the possibility of developing an evaluation method based on collective intelligence, as well as the need to improve refine the method in the future.
