Elsevier的影响因子正式公布！
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。
注：具体详细的计算规则以官方的说明更新为准
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？？
