Research Activity Classification based on Time Series Bibliometrics

INTRODUCTION In this paper, we aim to discover “distinguished” researchers who have not been widely known based on bibliometrics. In many cases, some criteria concerning the amount of research achievements, such as the number of papers published and citations received, are determined, and then the research activities are evaluated regarding whether the criteria are satisfied. However, the simple sum of the achievements is consequently beneficial to the elder researchers, and there is a problem in that researchers who have a significant achievement cannot be differentiated from those publishing a few papers over a long period of time. Also, it has been found that the transitions of the achievements of “distinguished” researchers exhibit some patterns (Bjork, Offer & Soederberg 2014). Therefore, this paper finds characteristic patterns from the time series changes of the international and domestic research achievements of “distinguished” researchers, and then it attempts to classify the researchers.
