유해화학물질 취급시설 관련 뉴스와 국민신문고 민원 트렌드 빅데이터 분석 = Big Data Analysis on News and Civil Complaint Trends Related to Hazardous Chemical Handling Facilities

다국어 초록 (Multilingual Abstract)

Since the 2013 revision of the Toxic Chemicals Management Act to the Chemical Substances Control Act, the evaluation of how internal and external environmental changes affect legal systems for facilities handling hazardous chemicals is crucial for prospective system enhancements. Through an analysis of news and civil complaints from 2014 to 2023, it was observed that both external news and internal civil complaints related to handling facilities peaked in 2019, declining as the legal system stabilized. News trends were tracked using Term Frequency(TF), while civil complaints were assessed using TF-IDF (Inverse Document Frequency) to identify significant keywords. The entity name analysis algorithm, Structured Support Vector Machine, was applied to investigate keyword relationships. Among the notices concerning handling facilities, civil complaints related to small quantity standards and small quantity handling facilities were the highest. Inquiries regarding damage reduction facility standards, such as bund walls and detectors, ranked prominently, suggesting a need for policy service improvements in this area.
