한국과 일본의 공공데이터포털 재난안전 데이터셋 및 서비스 비교 분석

초록

The purpose of this study is to obtain implications through comparative analysis of disaster safety datasets and servicesof representative public data portals in Korea and Japan. Comparative standards were established first. Then, dataset weightanalysis of disaster-type and safety-management -stage components, trend analysis through text mining on data-setdescriptions, and data quality and portal services analysis were performed. As a result public data sets were lower in Koreaboth numerically and proportionally than in Japan. Japan had a high proportion of disaster preparation and recovery datasetsin terms of disaster safety management, while Korea had a high proportion of prevention data-sets. In addition, in termsof disaster response collaboration, most of Korea has material management and resource support, but Japan has highproportion of emergency recovery and situation management of damaged facilities. In terms of data quality, Japan has manydatasets with four levels of Berners-Lee rating. However Korea has a high proportion of datasets with three levels ofBeners-Lee rating. However, Korea has a better data format for big-data utilization. Portal services are mainly centered onnatural disasters in Japan, but in Korea, they are centered on social disasters. The results of this study provide a referencefor the future direction of disaster safety public data portals in Korea.
