Abstract

A controlled group is closed compared to other organizations, which hinders collection of data and accurate analysis, so that it is hard to evaluate a controlled group's power structure and predict future changes using usual analytical methods including sociological approach. Analyzing a controlled group using SNA can allow for evaluation of inner power structure by revealing the relationships between members and identifying members with central roles given limited data. In this study, in order to evaluate changes in power structure, time-sequential SNA research was conducted by analyzing eigenvector centrality, which reflects individual influence and reveals the overall power structure. The result showed an improvement in accuracy compared to other centralities that contain individual degree or closeness, and made it possible to presume structural changes such as promotion or purge of a member.

통제조직은 외부로 정보가 공개되지 않으므로 그 속성을 직접 확인할 수 없어 사회학적 접근 등 일반적인 분석방법으로는 내부 권력 구조와 그 변화를 분석하기 어렵다. 직접적인 접근이 어려운 통제조직을 SNA를 활용하여 분석하는 방법은 간접적인 정보를 이용하여 구성원 간의 관계를 분석, 연결망을 식별하여 중앙성이 높은 인물을 판별함으로써 내부적인 권력 구조를 추정할 수 있다. 본 논문에서는 구성원 개인의 영향력과 전반적인 권력 구조를 고려하는 위세 중앙성 분석을 통해 실질적인 권력 서열의 변화를 평가하였다. 실험 결과 개인의 활동량이나 구성원간의 친밀도 등으로 산출되는 다른 중앙성 척도에 비하여 보다 정확하게 권력 구조의 추정이 가능하였으며, 새로운 구성원의 등장이나 탈퇴 등의 변화하는 구성원간의 상황을 포함한 변화 추정이 가능하였다.
