Abstract

The aim of this study is to examine the research trends of global scientific production of Geospatial Information (GI) papers from 1998 to 2013 by using keyword network analysis. This study constructed keyword network model through papers and keywords related to GI research retrieved from the Web of Science DB and performed keyword network analysis such as Degree Centrality, Betweenness Centrality, and Closeness Centrality. The results show that GI has been steadily applied to various fields, and also the research trends of GI techniques could be quantitatively characterized through keyword network analysis. This study result can be applied to establish the policies and the national R&D planning of geospatial information.

본 연구는 1998년부터 2013년까지 지리공간정보와 관련된 연구 논문에 대해 키워드 네트워크 분석 기법을 적용하여 분석하고 글로벌 차원에서 지리공간정보 연구의 흐름을 도출하는데 목적이 있다. 이를 위해 Web of Science 학술 자료 검색 엔진을 이용하여 지리공간정보와 관련된 논문과 주요 키워드를 추출하였다. 그리고 추출된 키워드를 이용해 키워드 네트워크 자료를 구축하고 시기별 키워드의 연결중심성과 매개중심성, 근접중심성을 분석하였다. 그 결과 다양한 분야에서 지리공간정보가 활용되어 왔음을 확인할 수 있었고 관련된 기술의 연구 동향을 계량적으로 파악할 수 있었다. 이러한 연구 결과는 지리공간정보에 대한 정책과 연구 개발 계획을 과학적으로 수립하는데 활용될 수 있을 것으로 판단된다.
