An Analysis of Research Trends in Institutional Repositories in South Korea (키워드 네트워크 분석을 활용한 국내 리포지터리 연구 동향 분석)

Abstract:  The purpose of this study is to analyze the research trends of repositories in Korea. We conducted keyword analysis and network analysis on repository-related papers indexed in the Korea Citation Index. The keyword frequency analysis identified major keywords including institutional repository, open access, collaborative preservation repository, data repository, and XML. Through keyword network analysis, seven clusters were identified. The largest cluster was related to cooperative shared storage, followed by clusters focusing on digital repository, data repository, open access and institutional repository, data standard technology, educational information systems, and metadata. A time series analysis showed that while XML-related research had been dominant in the early stage, recent trends indicate an increase in research related to research data and data repositories. This study is expected to contribute to diagnosing the current state of repository research in Korea, systematically analyzing trends, and suggesting future research directions.
