重新审视相对指标和临时真理
Revisiting Relative Indicators and Provisional Truths
摘要:
在2010年和2011年的讨论之后,科学计量评估者越来越多地放弃了相对指标,而倾向于将观察到的引用率与预期的引用率进行比较。后一种方法提供了误差值的参数,允许对引用分数的差异进行统计测试。进一步的步骤将是进行非参数统计(例如,前10%)给出了引用分布的极端偏态(非正态性)。为了回应上一期时事通讯中关于回归相对指标的呼吁,我们主张在引文影响指标的发展方面取得进一步进展。
英文摘要:
Following discussions in 2010 and 2011, scientometric evaluators have increasingly abandoned relative indicators in favor of comparing observed with expected citation ratios. The latter method provides parameters with error values allowing for the statistical testing of differences in citation scores. A further step would be to proceed to non-parametric statistics (e.g., the top-10%) given the extreme skewness (non-normality) of the citation distributions. In response to a plea for returning to relative indicators in the previous issue of this newsletter, we argue in favor of further progress in the development of citation impact indicators.
