Abstract

There are many metrics to evaluate the performance and status of journals. Among these, the journal impact factor (JIF) has become the dominant metric. The influence of JIF is illustrated by its widespread use to evaluate academic status, compensation, and funding decisions. However, as noted by Clarivate Analytics, the parent company of the Web of Science (WoS), the JIF should not be used without careful attention to the many phenomena that influence citation rates. To facilitate transparency, Clarivate Analytics provides all data used to determine the JIF. In addition, WoS provides other metrics for journal evaluation, including the article citation median and the review citation median. These metrics are represented as medians to minimize the confounding influence of a small number of highly cited articles that may occur when data are represented as means. Another feature of these WoS metrics is that data are separated according to different publication types of article (original research and review). To systematically compare these selected metrics, we used the data provided on the WoS web site to analyze 25 top ranked cardiovascular journals in the same mode as represented in the WoS citation distribution window. The results indicate that the article citation median and review citation median overcome several concerns that have been raised about the JIF and seem to provide enhanced objectivity as an indicator of journal impact in publishing original research and reviews. Therefore, we advocate that these additional WoS metrics might be preferentially considered as indicators of journal performance.

摘要

有许多指标可用于评估期刊的表现和地位。在这些指标中,期刊影响因子(JIF)已成为主导指标。JIF 的影响力体现在它被广泛用于评估学术地位、薪酬和资金决策。然而,正如科睿唯安(Clarivate Analytics)——Web of Science(WoS)的母公司所指出的,在使用 JIF 时,需要谨慎关注影响引文率的诸多现象。为了提高透明度,科睿唯安提供了用于确定 JIF 的所有数据。此外,WoS 还提供了其他用于期刊评估的指标,包括论文引文中位数和综述引文中位数。这些指标以中位数表示,以最大程度地减少因少数高被引论文而产生的混杂影响,而如果以平均值表示数据,则会产生这种影响。这些 WoS 指标的另一个特点是,根据不同的文章类型(原始研究和综述)对数据进行了分离。为了系统地比较这些选定的指标,我们以 WoS 引文分布窗口中表示的相同模式,使用 WoS 网站上提供的数据对 25 种排名最高的心血管期刊进行了分析。结果表明,论文引文中位数和综述引文中位数克服了对 JIF 的一些担忧,并且似乎作为发表原始研究和综述的期刊影响力的指标提供了更高的客观性。因此,我们主张优先考虑这些额外的 WoS 指标作为期刊绩效的指标。
