Analyzing Star Scientists through Researchers’ Collaborative Relations

Abstract

In this paper, we propose a new method to evaluate Star Scientists. Scientists, as researchers, are often evaluated by citation of their academic literatures which, however, has a problem in evaluating young researchers. In addition, researchers' competency of Collaborative Problem Solving is becoming important to promote Open Innovation. From these backgrounds, we focus on researchers' collaborative relations, and analyzed temporal transition of the centralities of co-authorship networks from academic literature database, as one of evaluation methods of researchers. As a result, we showed, this method identifies Rising Stars who are expected to be Star Scientists in the future. Furthermore, we discuss on effectiveness of the centralities of co-authorship networks as an evaluation index of researchers, comparing this proposed evaluation method with citation-based evaluation method from the viewpoints of (1) performance-based evaluation and ability-based evaluation, (2) leading indicator and lagging indicator and (3) knowledge accumulation and knowledge combination, etc.
