Abstract

In this study, we analyzed the current research state of Library and Information science in top 20 journals from 1990 to 2015, in subject and method perspectives. We developed weighted subject-method network to investigate on centralities of a subject and a method as well as their relations. This network is composed of subject nodes and method nodes and gives a weight on each node by topic occurrence. As a result, for 25 years, management information system, information need analysis, bibliometrics, information policy were top topics. Modeling, literature review, scientific research impact analysis, web data analysis were top methods. A recent rise of text mining is highlighted. We also analyzed communities made from the past 25 years and the recent 5 years. Bibliometrics is extending its field by applying various network analyzing algorithms. Text mining is specialized in medical information system and user interface. This result identifies the interests of excellent studies in Library and Information Science. It also can be fundamental resource for the development of Library and Information Science.

본 연구는 1990년부터 2014년까지 25년 간 국외 유수 문헌정보학 학술지들에 게재된 논문들을 대상으로 연구 주제와 연구 방법을 구분하여 현 선도 학술지의 연구 누적 현황을 분석하였다. 연구 주제와 연구 방법을 구분하고 그들 간의 관계를 살펴보기 위해 가중 주제-방법 네트워크를 개발하였다. 이는 주제와 방법으로 구성된 네트워크이며, 해당 토픽 소속 단어의 동시 출현 빈도를 기초로 주제와 방법에 가중치를 준다. 본 연구 결과에 따르면, 지난 25년간 경영정보시스템, 정보요구분석, 계량서지연구, 정보정책 등이 상위 연구 주제들이었다. 또한, 모델링, 개념/문헌연구, 연구협업분석, 웹데이터 분석 등이 상위 연구 방법들이었으며, 최근 텍스트 마이닝의 비상이 괄목할 만하다. 빈번히 짝을 이루는 연구 주제들과 연구 방법들의 지난 25년간의 군집들과 최근 5년간의 군집들을 살펴보면, 계량서지연구가 네트워크분석 방법들을 다수 적용하면서 그 저변을 넓히며 자리를 확고하게 하고 있으며, 텍스트 마이닝이 의료정보시스템, 이용자인터페이스에 특화되고 있음을 확인할 수 있다. 이러한 연구 결과는 문헌정보학의 선도 연구자들의 관심 연구 영역과 관점을 확인시켜주고, 향후 문헌정보학 발전을 위한 연구 설계의 기초자료로 활용될 수 있다.
