본 연구에서는 ‘학술지의 피인용횟수 순위’를 적용한 tapered h-지수의 변형지표 Kor-hT를 고안하여 제안하였다. Kor-hT의 의미를 평가하기 위하여 Kor-hT 지수 값의 중복률 및 지수 값과 평가요소 사이의 연관성 변화를 다른 학술지 평가지표인 h-지수, tapered h-지수 및 IF와 비교 분석하였다. 지수 값의 중복률 분석은 지표의 변별력을 살펴보기 위한 것이며, 지수 값과 평가요소와의 상관관계 분석은 지표의 평가요소인 피인용횟수 및 논문 수가 지수 값에 각각 어떻게 반영되는지를 알아보기 위한 것이다. 분석을 위해 2008년부터 2010년까지의 한국학술지인용색인(KCI) 3개년 데이터를 사용하였다. 분석 결과 본 연구에서 제안한 Kor-hT가 비교 대상 지표에 비해 지수 값의 중복률이 가장 낮아 높은 변별력을 보였으며, 지수 값과 평가요소와의 상관관계에 있어서도 피인용횟수와 논문 수 모두에서 상관관계가 가장 높은 것으로 나타났다.

Abstract

This study describes the meaning of and the formula for Kor-hT, which is a modified index built on the tapered h-index by applying ‘the ranking according to the number of citations of journals’. This study evaluated the de-duplication rate of index values of Kor-hT and analyzed the change in the correlation between the index values and evaluation elements using the Korea Citation Index data from 2008 to 2010. Kor-hT is compared with h-index, tapered h-index, and IF. As a result, Kor-hT appeared to be superior to other indexes on de-duplication rate. It is also shown that there is a very strong positive correlation between the evaluation elements, the number of citations and the number of articles of journals, and the index values of Kor-hT.

Abstract

Even though the overall scholarly community has recognized a dramatic growth and changes in the Information Science research in Korea over the last few decades, there are still only few studies that have identified the changes in terms of long-term and dynamic point of view. We have analyzed 1,007 IS-research articles from leading Korean journals in KCI (Korea Citation Index), published between 2000 and 2011. To discern the trendline of changes in research interests over time, we conducted a time-series analysis by developing grounded subject scheme from the article set and checking the growth rate of the number of published articles and title keywords. A comparative analysis was also conducted by constructing and comparing co-word maps over time to discover visible changes in research topics over this 12-year period of the IS-research in Korea. As a result, we identified some developments and transformations in major subject areas and knowledge structure of the IS-research in Korea over time. The major trend we discovered is that IS-studies over the 12-year period evolved from system-oriented research to library-application research. The changes are especially observed in knowledge management, Web-based system evaluation, and information retrieval areas. When compared to the results of other studies, the result of our study may serve as an evidence of the localization of Korean IS-studies in the first decade of the 21st century.
