修正赫希指数hm计及多合著者的案例研究
A Case Study of the Modified Hirsch Index hm Accounting for Multiple Co-authors
摘要:
J. E.赫希(2005年)引入了h指数,通过科学家论文的最大数量h来量化个人的科学研究成果,这些论文至少被引用了h次。这个所谓的赫希指数可以很容易地修改,以考虑到多个合著者,通过计算论文分数根据(倒数)的作者人数。我列举了26个物理学家的经验案例来说明这种修正的效果。虽然原始的和修改后的赫希指数之间的相关性是相对较强的,数据集的安排是显着不同的,这取决于它们是否被放入根据原始或修改后的指数的值的顺序。
英文摘要:
J. E. Hirsch (2005) introduced the h-index to quantify an individual's scientific research output by the largest number h of a scientist's papers, that received at least h citations. This so-called Hirsch index can be easily modified to take multiple co-authorship into account by counting the papers fractionally according to (the inverse of) the number of authors. I have worked out 26 empirical cases of physicists to illustrate the effect of this modification. Although the correlation between the original and the modified Hirsch index is relatively strong, the arrangement of the datasets is significantly different depending on whether they are put into order according to the values of either the original or the modified index.
