Comparative Analysis of Disaster and Safety Datasets, Data Quality, and Services in Korean and Australian Public Data Portals

Abstract

The objective of this study is to design improved plans for disaster and safety management through comparative analysis of datasets comprising details regarding the disaster and safety sector that are available in Korean and Australian public data portals and thereby examine the associated portal strategies and national operating systems To this end, based on previous studies and national public data portal evaluation standards, public data portal comparison standards were established. Furthermore, quantitative configuration analysis, data mining analysis, data quality analysis, and various service analyses were conducted. Consequently, it was found that compared to the Australian public data portal, the number and proportion of public data openings for disaster and safety management are significantly smaller in the Korean public data portal. The number of prevention datasets available in both countries accounts for the highest proportion in disaster and safety management. In addition, “supply management and resource support” accounts for the majority of Korean disaster response collaborations, whereas in the case of Australia, “comprehensive situation management” has a high proportion. In terms of data quality, Australian datasets include 69.54% of the total insoluble data, which implies inefficient data quality management. However, there are merely few Korean insoluble datasets. Through comparative analysis of the national operating systems, it was found that detailed guidelines for public data are available in Australia. However, the Korean public data portal is operated in accordance with the comprehensive Framework Act on Intelligence Informatization. Hence, a promotion strategy operation policy has to devise for the Korean public data portal to expand the usage of public data in the disaster and safety sector, along with quantitative growth policies that will increase the number and proportion of public data in the disaster and safety sector.
