基于改进的h指数的学者评价研究

Scholar Evaluation Research Based on an Improved h-index

h指数是目前常用的科学计量指标之一,其通常被用来衡量学者的学术能力。针对h指数忽略高被引论文等问题,本文对不同h指数时论文的被引情况进行了深入分析,计算出了h指数一定时的论文平均被引数。在此基础上,提出了一个新的指标:hc指数。该指标由hc_1指数与hc_2指数构成,hc_1指数用来衡量学者的学术能力是否超出或低于当前h指数下的平均数值,hc_2指数用来衡量作者近年来的学术活跃程度。以数字图书馆、数字档案馆与数字博物馆领域的学者为对象进行的实证研究表明,hc指数能够较好地衡量作者的学术能力,缓解了h指数忽略高被引论文等问题,可用来发现近年来的活跃学者,并能依据不同领域的实际情况来进行评价。

The h-index is one of the common scientific indicators that are used to measure the academic ability of scholars.In view of the shortcomings of the h-index,which ignores often-cited papers,this paper analyzes the frequency of citation of papers with different h-indexes and calculates the average number of citations of papers with a certain h-index.On this basis,a new index is proposed:the hc index,which consists of an hc1 index and an hc2 index.The hc1 index is used to measure whether the scholar’s academic ability is higher or lower than the average value of the current h index;the hc2 index is used to measure the author’s academic activity in recent years.Scholars in the fields of digital libraries,digital archives,and digital museums have been selected for empirical research.The research shows that the hc index can better measure the author’s academic ability and that it can solve the problem of the h index ignoring often-cited papers.It can also be used to find scholars who have been active in recent years,and it can evaluate scholars according to the characteristics of different fields.
