인천광역시 국가유산 정책의 시기별 변화 분석:텍스트마이닝 기법을 활용한 정책 흐름 비교 연구 = Analyzing temporal shifts in Incheon’s Korea Heritage policies: A text mining approach to Policy Trend Analysis

다국어 초록 (Multilingual Abstract)

This study analyzes the policy trajectory of Incheon Metropolitan City's national heritage governance, focusing on its official implementation plans in light of the systemic changes following the enactment of the FRAMEWORK ACT ON NATIONAL HERITAGE. By applying text mining techniques, this research identifies key embedded keywords and traces the thematic evolution within these policy documents over time.
The analysis reveals a distinct three-phase transition. Phase 1 (2012–2016) was characterized by preservation-focused policies centered on World Heritage and the Ganghwa region. Phase 2 (2017–2021) saw a shift towards strengthening the transmission of intangible heritage while concurrently promoting initiatives related to Goryeo Dynasty history, inter-Korean exchanges, and World Heritage. Finally, the current Phase 3 emphasizes region-based strategies for both preservation and utilization, coupled with a significant expansion of citizen participation.
This study is significant in that it quantitatively analyzes a local government's policy documents to empirically illuminate the diachronic shifts in Incheon’s strategic priorities. Future research is warranted to complement this analysis by examining its linkages with national-level plans and actual policy implementation outcomes.
