How Can We Elucidate the Lost Place Identity from the Great East Japan Earthquake by Using Spoken Memories and the Location of Victims?: Using Iwate Prefecture “Lost Homes”Project Data

Abstract

To elucidate the lost place identity using the memories told by the victims of the Great East Japan Earthquake Disaster, we conducted the following analysis. 1) Through text mining, we were able to extract characteristic keywords contained in the testimonies of residents recorded in each district. 2) Correspondence analysis using the selected keywords showing characteristics of community could classify four categories of communities such as urban, town, town + fishing, and fishing village. 3) By performing kernel density estimation on the distribution of location information of residents' testimonies, we were able to efficiently extract areas where testimonies in each district were concentrated.
