A novel clustering method for examining and analyzing the intellectual structure of a scholarly field

지적 구조 분석을 위한 새로운 클러스터링 기법에 관한 연구

Abstract

Recently there are many bibliometric studies attempting to utilize Pathfinder networks(PFNets) for examining and analyzing the intellectual structure of a scholarly field. Pathfinder network scaling has many advantages over traditional multidimensional scaling, including its ability to represent local details as well as global intellectual structure. However there are some limitations in PFNets including very high time complexity. And Pathfinder network scaling cannot be combined with cluster analysis, which has been combined well with traditional multidimensional scaling method. In this paper, a new method named as Parallel Nearest Neighbor Clustering (PNNC) are proposed for complementing those weak points of PFNets. Comparing the clustering performance with traditional hierarchical agglomerative clustering methods shows that PNNC is not only a complement to PFNets but also a fast and powerful clustering method for organizing informations.

패스파인더 네트워크를 사용하여 지적 구조의 분석과 규명을 시도한 여러 연구가 발표되었다. 패스파인더 네트워크는 다차원척도법에 비해서 여러 장점을 가지고 있지만 구축 알고리즘의 복잡도가 매우 높아서 실행 시간이 오래 걸리며, 전통적인 지적 구조 분석에 유용하게 사용되어온 군집분석을 함께 적용하기가 어려운 것이 단점이다. 이 연구에서는 이와 같은 패스파인더 네트워크의 약점을 보완할 수 있는 새로운 기법으로 병렬최근접이웃클러스터링(PNNC) 기법을 제안하였다. PNNC 기법의 클러스터링 성능을 전통적인 계층적 병합식 클러스터링 기법들과 비교해본 결과 효과성과 효율성 양면에서 기존 기법보다 우세한 것으로 확인되었다.
