2026年自然指数的重大变化

2026年发布的最新自然指数“研究领导者”排名在范围和方法上发生了重大变化,是数据库发展的一个里程碑。有两个关键的发展:应用科学和社会科学期刊的增加,以及对研究文章如何分配主题的彻底改革。

在对来自不同学科和领域的4000多名研究人员进行调查后,选择了额外的期刊(和会议),以确定他们希望发表最重要研究的出版场所。

根据本次调查后提出的应用科学场所进行了初步排名,17种新期刊和一次会议的最终名单中的文章现已完全整合到数据库中。此外,通过同一调查过程确定的15种社会科学期刊的研究文章现在也被添加进来,以进一步扩大学科覆盖面。

自然指数中有哪些出版物?

当前的12个月窗口期包括来自以下178种科学期刊和会议记录的主要研究文章的数据:

尽管每个学科领域添加到数据库中的标题数量相似,但应用科学期刊包含的文章要多得多,到2025年约为20200篇,而社会科学期刊向数据库中添加了约2000篇文章。

第二个重大变化与主题分类有关

到目前为止,数据库中的大多数文章都是根据其期刊的主要学科分配到一个主题领域的。例如,《柳叶刀》中的所有文章都被归类为健康科学文章,《高级功能材料》中的全部文章都被归入物理科学等。唯一的例外是五种被归类为多学科的期刊(包括《自然》和《科学》)。

从这些排名发布之日起,数据库中的所有出版场所实际上都将被视为多学科,每篇文章都被分配到一个主题领域。

这些变化如何影响与前几年排名的比较?

2024年和2025年的新期刊文章已被添加,以帮助比较,新的主题方法已针对2015年以来的所有排名进行了计算。

这意味着我们可以继续关注自那一年以来数据库广泛涵盖的学科的长期趋势,换句话说,是物理科学、化学、地球与环境科学和生物科学这四个自然科学领域。对于后来引入关键期刊的学科——2022年的健康科学,现在的应用科学和2024年的社会科学——在添加标题时应该考虑年份之间的比较,但可能会有一些“同比”分析。
