迈向新冠指标:实证分析

Towards a new crown indicator: An empirical analysis

摘要:

我们提出了一个实证比较两个规范化机制的研究绩效的引文为基础的指标。这些机制的目的是使该领域的引文计数和出版物的出版年份标准化。一种机制应用于我们研究所目前所谓的冠状指示器中。另一种机制应用在我院拟采用的新冠指标中。我们发现,在高聚集水平,如在大型研究机构一级或在国家一级,两种机制之间的差异非常小。在较低的汇总级别,如在研究小组一级或在期刊一级,这两种机制之间的差异稍大。我们特别注意最近出版物的处理方式。这些出版物的引用次数通常很低,因此应特别小心处理。

英文摘要:

We present an empirical comparison between two normalization mechanisms for citation-based indicators of research performance. These mechanisms aim to normalize citation counts for the field and the year in which a publication was published. One mechanism is applied in the current so-called crown indicator of our institute. The other mechanism is applied in the new crown indicator that our institute is planning to adopt. We find that at high aggregation levels, such as at the level of large research institutions or at the level of countries, the differences between the two mechanisms are very small. At lower aggregation levels, such as at the level of research groups or at the level of journals, the differences between the two mechanisms are somewhat larger. We pay special attention to the way in which recent publications are handled. These publications typically have very low citation counts and should therefore be handled with special care.
