统计出版物和引用:越多越好吗?

Counting publications and citations: Is more always better?

Ludo Waltman, Nees Jan van Eck, Paul Wouters

摘要:

越多总是越好吗?我们在文献计量学指数的背景下解决这个问题,该指数旨在通过计算高被引出版物的数量来评估单个研究人员的科学影响。我们提出了一个简单的模型,在该模型中,出版物的引用数量不仅取决于出版物的科学影响,而且还取决于其他“随机”因素。我们的模型表明,更多并不总是更好。事实证明,最有影响力的研究人员在高被引出版物方面的表现可能比他们一些影响力较小的同事系统性地低。该模型还提出了一种改进的计算高引用出版物的方法。

英文摘要:

Is more always better? We address this question in the context of bibliometric indices that aim to assess the scientific impact of individual researchers by counting their number of highly cited publications. We propose a simple model in which the number of citations of a publication depends not only on the scientific impact of the publication but also on other 'random' factors. Our model indicates that more need not always be better. It turns out that the most influential researchers may have a systematically lower performance, in terms of highly cited publications, than some of their less influential colleagues. The model also suggests an improved way of counting highly cited publications.
