Abstract

For many decisions in science, evaluators have to select, assess, and rank authors based on their scientific achievements. However, the most diffused scientific performance bibliometric metric – the h index – produces many ties, precluding its use to define a full ranking of the authors. In turn, recently, Jorge Hirsch proposes the h-alpha index (which measures the number of papers of the h core in which the author was the scientific leader)and the associated r-alpha index(percentage of papers belonging to the h core in which the author was leader)to capture the concept of scientific leadership. We suggest using this last measure to break the ties of the h index. The method is extremely simple and provides a complete solution to this critical problem of the h index. To that end, we develop a two steps procedure, which is able to produce a more granulated ranking of the authors.

无条件地衡量科学绩效:科学领导力是解决方案吗?
在许多科学决策中,评价者必须根据作者的科学成就来选择、评估和排名。然而,最广泛的科学绩效文献计量指标——h指数——产生了许多联系,因此无法使用它来确定作者的完整排名。最近,豪尔赫·赫希(Jorge Hirsch)提出了h-alpha指数(衡量作者在h核心中担任科学领导者的论文数量)和相关的r-alpha指数(作者在h核心中担任领导者的论文的百分比)来描述科学领导力的概念。我们建议使用最后一种方法来打破h指数的联系。该方法非常简单,完全解决了h指数这一关键问题。为此,我们开发了一个两步程序,它能够产生更细粒度的作者排名。
