自引修正对Egghe g指数的影响

The influence of self-citation corrections on Egghe's g index

Michael Schreiber

摘要:

g指数是由Leo Egghe引入的,作为Hirsch指数h的改进,用于衡量一组文章的整体引用记录。它比h指数更好地考虑了引文的高度倾斜的频率分布。我建议通过排除自我引用来提高g指数。我在物理学中计算了九个实际案例,并比较了有和没有自我引用的h和g值。正如预期的那样,g指数比h指数更好地表征数据集。自引的影响似乎是更显着的g指数比h指数。

英文摘要:

The g index was introduced by Leo Egghe as an improvement of Hirsch's index h for measuring the overall citation record of a set of articles. It better takes into account the highly skewed frequency distribution of citations than the h index. I propose to sharpen this g index by excluding the self-citations. I have worked out nine practical cases in physics and compare the h and g values with and without self-citations. As expected, the g index characterizes the data set better than the h index. The influence of the self-citations appears to be more significant for the g index than for the h index.
