据悉,最新的2020JCR影响因子将于6月29日,也就是下周一公布。
除了这个俗称的SCI影响因子外,Elsevier基于Scopus数据库,也每年发布一个影响因子指标,正式名称为CiteScore,但每年发布均极为低调,小编刚刚发现:Elsevier又悄悄地发布了最新的CiteScore。
往年的CiteScore,我们可以看成是一个三年的影响因子,但根据刚刚公布的数据,今年的算法变动很大,我们稍后给出点简单的分析说明。
先看看这个公布数据中,CiteScore值在20分以上的期刊,后面我们会给出CiteScore的计算方法等,以及一些期刊的分值点评,比较一下CiteScore与JCR影响因子的差异。
注:以下数据全部来自于Scopus数据库,系人工整理,如有出错,尽请指出,也请谅解,注意以下排名,是在该数据库的Source Type中,选择了Journals排出来的,但有几个期刊小编没见到过。

几点点评
一. Ca-A Cancer Journal for Clinicians,最近各路神仙都预测其最新JCR影响因子将超过300,但CiteScore 今年计算方法一变后,达到了惊人的435,当然是因为计算了多年引用量的关系。理论上,现在很难拿JCR影响因子与CiteScore再来对比了。
二. 我们平时言必提Nature, Science, Cell 三个顶尖刊物,在CiteScore这个排名中,悄悄地躲在了后面,可见两个评价指标的差异之大。
三, 今年CiteScore的新的计算方式如下:
2016-2019年的发表的文献(特定类型)数作为分母,2016-2019年的发表的这些文献自发表来的所有引用(不限于当年)作为分子。
而JCR影响因子对应的则是,分母取前两年发表的特定类型文章数,分子取前两年发表的所有文献数在第三年的被引次数。
然后,JCR影响因子基于WOS数据库,CiteScore基于Scopus数据库,两者收录的期刊范围差别也非常大。
所有这些,都导致了两个指标的差异。
不过,今年的JCR影响因了也推迟了,鉴于这两年科技评价方式导向等的变化,JCR影响因子会不会也来个大改版呢??
