摘要
【目的】比较不同学科期刊的Cite Score(CS)与影响因子(IF),分析CS和IF在学术期刊评价中的异同。【方法】选择《期刊引证报告》(JCR)中集合引用半衰期不同的8个学科,全方位统计分析这8个学科期刊的CS和IF。IF来源于科睿唯安公司2016年6月发布的2015年度的JCR,CS来源于Elsevier出版集团2016年12月发布的2015年度Journal Metrics。【结果】选取的8个学科380种期刊,CS与IF相关系数r为0.922,P为0.000。8个学科中均表现为CS大于IF的期刊居多,对于统计与概率论、传播学、政治学和历史学等引用半衰期较长的学科,二者差异具有统计学意义。多数多学科和综合性医学期刊的IF大于CS,但二者的相关系数依然达到了0.871。【结论】CS和IF在期刊影响力评价中具有高度的一致性。对于评价被引半衰期较长的学科期刊,CS表现出一定的优越性。
[Purposes] This study aims to analyze the difference between Cite Score（ CS） and impact factor（ IF） in academic journal evaluation by comparing CS in different discipline journals. [Methods]Eight disciplines with different aggregated cited halflife in the Journal Citation Report（ JCR） database were selected. All-round statistical analysis was adopted to discuss journal CS and IF in different disciplines. The IF was derived from the JCR in 2015 published by Clarivate Analytics,and CS was collected from the Journal Metrics database in 2015 published by the Elsevier Group. [Findings]The correlation coefficient of CS and IF is 0.922（ P = 0.000） in the 380 journals from the selected 8 disciplines. The CSs of most journals in the eight disciplines are larger than IFs. The differences between CS and IF have statistical significance in four disciplines,namely statistics and probability theory,communication,political science,and history. The IFs of most journals in multidisciplinary and comprehensive medicine journals are larger than CSs,but the correlation coefficient of CS and IF is 0.871. [Conclusions] CS has a high level of consistency with IF in journal impact evaluation. The CS shows a certain degree of superiority for journal evaluation in longer cited half-life discipline.
