The purpose of this study is the preliminary index was derived through the literature review and comparison of public design indices of Korea and other nations and then, its indicators were verified through the text mining analysis using big data to suggest the final index for utilization of abolished school facilities. The results of this study are summarized as follows.
First, with the review on relevant previous studies, public design indices of Korean and other nations, and possibility of applicability for each abolished school facility type, 5 upper categories (economical, public spatial, physical, regional, and environmental and design aspects) and 15 indicators and detailed indicators were deduced. Second, for the verification of the preliminary index for utilization of abolished school facilities, the TF analysis and the TF-IDF analysis, of text mining techniques, were performed. Third, with the analysis of association between keywords, additional indicators were deduced. With the algorithm, calculated using this equation, association rules with a support value of 0.01 or above and a confidence value of 0.3 or above were identified among the screened articles, and among them, 15 association rules having the highest lift values are as follows. Fourth, the final index classification system could classify indicators into the economic, public space, physical, business planning, facility, and local environment. In addition, by stereotyping the indicators dentified by the linkage analysis in Chapter 6.2, population distribution characteristics, and facilities and land characteristics were added as indicatore categories.
