关于h指数的意义
On the meaning of the h-index
摘要：
h指数（h-index）是指一个人至少发表了h篇论文，被引用次数至少为h次的数值，它已经成为评估科学家被引用影响力的一个流行指标。正如赫希的原始著作中已经指出的那样，并从物理学家代表性样本的数据中得到证明，sqrt{c}以h为尺度，其中c是对个人的引用总数。因此，sqrt{c}似乎等价于h索引。作为这种等效性的进一步检验，该样品的比率s=sqrt{c}/2 h的分布在约1处尖锐地达到峰值。这种分布中的异常值揭示了个体出版记录的根本不同类型。
英文摘要：
The h-index -- the value for which an individual has published at least h papers with at least h citations -- has become a popular metric to assess the citation impact of scientists. As already noted in the original work of Hirsch and as evidenced from data of a representative sample of physicists, sqrt{c} scales as h, where c is the total number citations to an individual. Thus sqrt{c} appears to be equivalent to the h index. As a further check of this equivalence, the distribution of the ratio s=sqrt{c}/2h for this sample is sharply peaked about 1. The outliers in this distribution reveal fundamentally different types of individual publication records.
