최근 다양한 학문 분야는 대내외적 요인으로 인해 학제적 연구 흐름에 영향을 받고 있는 추세이다. 본 연구는 문헌정보학 분야를 대상으로 학제성과 연구 영향력의 상관관계를 분석하고자 하였다. 이를 위해 2011년 JCR(Journal Citation Reports)의 학술지 영향력 지수 상위에 해당하는 문헌정보학 학술지 10종을 선정하여 WoS(Web of Science) 인용색인 DB에서 2006년부터 2010년까지 1,873편의 논문의 참고문헌 데이터를 대상으로 분석하였다. 동시인용 네트워크 분석과 선정된 4가지 학제성 지수를 사용하여 문헌정보학 분야의 학제적 구조를 파악하고 학제성과 연구 영향력 사이의 상관관계를 분석하였다. 분석 결과를 통해 문헌정보학의 학제적 구조를 제시하였으며, 학제성 지수 중 매개중심성은 학술지 영향력 지수(5년) 그리고 논문당 영향도(Article Influence Score)와 통계적으로 유의한 상관관계가 있음이 밝혀졌다.

Abstract

As interdisciplinary research has been dominant in various fields, the purpose of this study is to analyze the relationship between interdisciplinarity and research impact in the field of Library and Information Science. For a data set, ten journals ranked as the top of 2011 JCR’s in terms of JIF (Journal Impact Factor) were selected. The citation data of 1,873 articles from the ten journals were collected from the WoS during the period from 2006 to 2010. In order to achieve the purpose of this study, as network analysis was conducted to investigate the interdisciplinarity of LIS field, interdisciplinarity indicators, and research impact factors were statistically analyzed. The findings of this study confirmed the interdisciplinary knowledge structure of the LIS field as previous studies identified. More importantly, this study demonstrated that a positive correlation existed between interdisciplinarity represented as betweenness centrality and research impact.

Abstract

Since information scientists have begun trying to quantify significant research trends in scientific publications, ‘-metrics’ research such as ‘bibliometrics’, ‘scientometrics’, ‘informetrics’, ‘webometrics’, and ‘citation analysis’ have been identified as crucial areas of information science. To illustrate the dynamic research activities in these areas, this study investigated the major contributors of ‘-metrics’ research for the last decade at three levels: nations, institutions, and documents. ‘-metrics’ literature of this study was obtained from the Science Citation Index for the years 2001-2011. In this analysis, we used Pathfinder network, PNNC algorithm, PageRank and several indicators based on h-index. In terms of international collaborations, USA and England were identified as major countries. At the institutional level, Katholieke University, Leuven and the University of Amsterdam in Europe and Indiana University and the Office of Naval Research in the USA have led co-research projects in informetrics areas. At the document level, Hirsch’s h-index paper and Ingwersen’s web impact factor paper were identified as the most influential work by two methods: PageRank and single paper h-index.

이 연구는 한국에서 SCIE 논문을 가장 활발하게 발표하고 있는 분야인 재료공학과 대학교수 449명이 2006년부터 2010년까지 발표한 SCIE 논문수와 피인용 횟수를 측정하고 이에 영향을 미치는 요인을 구체적으로 규명하고자 하였다. 연구 결과 논문수가 많은 교수가 피인용 횟수도 높은 것으로 나타나 외국의 선행연구 결과와 유사하였고, 논문수에 영향을 주는 요인은 교수의 직급, 출신학부, 재직 대학의 소재지일 수 있다는 것을 확인하였다. 피인용에 영향을 주는 요인으로 인적 특성 가운데 출신학부가 있었고, 환경적 특성으로 재직 대학의 소재지가 서울인지 지방인지에 따라 피인용 횟수에 뚜렷한 차이가 있음을 확인하였다. 장기적으로 국내 SCIE 논문의 피인용을 증진하기 위해서는 피인용을 촉발할 수 있는 기초 연구에 보다 많은 지원을 해야 하고, 대학과 연구비 지원기관의 연구성과 평가에 피인용 횟수도 포함시키는 등 평가방식도 보완할 필요성이 제기되었다.

Abstract

This study pointed the factors affecting the number of articles and citations in material science which is the most active publishing disciplinary in South Korea. This was conducted by gathering the information on SCIE which had been published by 449 Korean professors in material science from 2006 to 2010. One of the results was that the professors who had published more papers received more citations than those who did not, reconfirming former studies abroad. It was observed that the factors majors impacting on the number of papers may be their academic positions, educational backgrounds (particularly undergraduates), and places of work. The number of citations was affected by the authors’ undergraduate and their locations of the work. This study suggested a need for more supports on basic researches by universities and funding bodies and an amendment of performance measures to include the number of citations.
