H指数

学者发表的论文按引用数逆序排列,得到其H指数

H指数(H index)是一个混合量化指标,可用于评估研究人员的学术产出数量与学术产出水平。H指数是2005年由美国加利福尼亚大学圣地亚哥分校的物理学家乔治·E·希尔施英语Jorge E. Hirsch[1]提出的。

定义

H指数的计算基于其研究者的论文数量及其论文被引用的次数。赫希认为:一个人在其所有学术文章中有N篇论文分别被引用了至少N次,他的H指数就是N。[1][2]美国耶鲁大学免疫学家理查德·弗来沃英语Richard A. Flavell发表的900篇文章中,有107篇被引用了107次以上,他的H指数是107。

可以按照如下方法确定某人的H指数:

  1. 将其发表的所有SCI论文[來源請求]按被引次数从高到低排序;
  2. 从前往后查找排序后的列表,只要当前的引用量大于当前的索引值,则H指数加1,最后得到的结果即为最终的H指数。
