【目的】 探讨基于InCites数据库中论文被引频次百分位创建期刊百分位数指标的方法,比较不同百分位数指标的期刊评价效果。【方法】 以2018年版JCR中多学科交叉科学期刊及其2017—2018年发表的论文为研究对象,根据InCites数据库中论文被引频次学科领域百分位(Percentile in Subject Area,PSA)创建期刊百分位数指标(Journal Indicator of Percentage Rank,JIPR),包括JIPR4、JIPR6、JIPR8、JIPR10、JIPR100和平均PSA(aPSA),比较不同JIPR对多学科交叉科学期刊的评价效果。【结果】 68种期刊的JIPR4呈偏态分布,其他JIPR呈正态分布,多数指标之间呈高度相关,不同等级JIPR之间相关度更高;影响因子与aPSA排序位次变化较大的期刊多是发表综述文献较多、单篇高被引论文对影响因子贡献较大的期刊。【结论】 与影响因子相比,多数JIPR有明显优势,其中aPSA可能是最理想的期刊评价指标。
[Purposes] This paper probes into the method of establishing journal indicator of percentage rank (JIPR) based on the percentile in subject area (PSA) of papers in InCites database and compares the journal evaluation results of different JIPRs. [Methods] JIPRs of papers published in 2017-2018 on journals of multidisciplinary science in 2018 JCR were established based on their PSAs in InCites database, including JIPR4, JIPR6, JIPR8, JIPR10, JIPR100, and average percentile in subject area (aPSA). The evaluation results of these journals based on different JIPRs were compared. [Findings] JIPR4s of the 68 journals show skewed distribution and other JIPRs show normal distribution. Most indicators are highly correlated, particularly the JIPRs. Journals with great variation in impact factor and aPSA rank are those with more review articles and great contribution of a single highly-cited paper to the impact factor. [Conclusions] Most JIPR indicators are superior to impact factor in journal evaluation, especially aPSA.
