계량서지적 네트워크 분석을 위한 중심성 척도에 관한 연구
Centrality Measures for Bibliometric Network Analysis
초록
최근 일부 계량서지학 연구에서 사회 네트워크 분석 분야의 도구인 중심성 분석 기법을 도입하려는 시도가 나타나고 있다. 그런데 사회 네트워크를 대상으로 개발된 중심성 척도는 노드간 연결에 대한 가중치를 반영하지 않는 단점이 있다. 이 연구에서는 가중 네트워크인 계량서지적 자료에 대해서 중심성을 분석할 수 있는 새로운 척도를 네 가지 제시하였다. 제안된 척도의 유용성을 검증하기 위해서 저자동시인용 네트워크, 용어 동시출현 네트워크, 웹 사이트 동시링크 네트워크의 세 가지 실제 자료에 대해서 중심성 분석을 수행하였다. 분석 결과에서는 제안된 중심성 척도가 계량서지적 네트워크를 대상으로 개별 노드의 입지와 영향력을 파악하는데 있어서 매우 유용함이 확인되었다.

Abstract
Recently, some bibliometric researchers tried to use the centrality analysis methods and the centrality measures which are standard tools in social network analysis. However the traditional centrality measures originated from social network analysis could not deal with weighted networks such as co-citation networks. In this study, new centrality measures for analyzing bibliometric networks with link weights are suggested and applied to three real network data, including an author co-citation network, a co-word network, and a website co-link network. The results of centrality analyses in these three cases can be regarded as promising the usefulness of suggested centrality measures, especially in analyzing the position and influence of each node in a bibliometric network.
