EM和EM '-指数序列的构造及其在学者科学评价中的应用

EM and EM'-index sequence: Construction and application in scientific assessment of scholars

Anand Bihari, Sudhakar Tripathi, Akshay Deepak, Prabhat Kumar

摘要:

大多数科学计量指标只使用一篇文章的引用总数,并产生一个单一的数字来对学者进行科学评估。虽然这一概念计算起来非常简单,但它无法显示学者在一段时间或一年内的科学生产力和影响力。为了克服这一点,已经提出了几个时间序列指标,这些指标考虑了学者整个研究生涯的引文。然而,这些指标未能对具有相同或非常相似的指标值的两名学者进行比较评估。为了克服这一缺陷,提出了h指数序列来评估学者在特定时间跨度内的影响,并比较多个学者在他们的职业生涯中的相似阶段。h指数序列基于h指数公式。与h指数相关的一个主要问题是它完全忽略了科学评估中的过度引用; h指数序列也表现出类似的行为。为了克服这些局限性,本文讨论了EM和$EM^{'}$ -索引序列,并基于89位学者的全部出版物的年度引文计数进行了实证研究。给定年份的EM和$EM^{'}$ -索引序列的元素显示了该年学者的影响。我们的结论是,EM和$EM^{'}$ -索引序列可以作为一个替代指标来评估学者的影响。

英文摘要:

Most of the scientometric indicators use only the total number of citations of an article and produce a single number for scientific assessment of scholars. Although this concept is very simple to compute, it fails to show the scientific productivity and impact of scholars during a time-span or in a year. To overcome this, several time series indicators have been proposed that consider the citations from the entire research career of a scholar. However, these indicators fail to give a comparative assessment of two scholars having same or very similar index value. To overcome this shortcoming, h-index sequence was proposed to assess the impact of scholars during a particular time-span and to compare multiple scholars at a similar stage in their careers. The h-index sequence is based on the h-index formulation. One of the main issues related to the h-index is that it completely ignores the excess citation in scientific assessment; h-index sequence also exhibits a similar behaviour. To overcome these limitations, in this article, we have discussed the EM and $EM^{'}$-index sequence, and performed an empirical study based on yearly citation count earned from all publications of 89 scholars' publication data. The element of the EM and $EM^{'}$-index sequence for a given year shows the impact of a scholar for that year. We conclude that the EM and $EM^{'}$-index sequence could be used as an alternative metrics to asses the impact of scholars.
