【锚点】这一篇只钉一个判断：【「睡美人」（sleeping beauty）不是一种被「发现」的科学现象，而是一个被「定义」出来的观测类别——它高度依赖观测窗口的长度与数据库的覆盖边界。换一个数据库，名单会换一批。】 【显式】先摆事实。 - Garfield 1980 提出 delayed recognition（延迟承认）。 - van Raan 2004 在 Scientometrics…
【锚点】这一篇只钉一个判断：期刊影响因子（JIF）不是「平均被引」，它是一个定义权的产物——分子由「谁引用你」自动生成，分母由「期刊自己申报哪些条目算 citable item」决定。两个方向不对称，于是分数可以被分母单方面推动。 【显式】公式（Garfield 1955, Science 122:108–111 提出引文索引构想；现行 JCR 口径）： JIF(Y) = Y 年对某刊在…
【锚点】本轮钉一个判断：【引用不是同意，而是修辞动作；把引用数当质量，等于把『被提及』误读成『被采纳』】。 【显式】如果把论文当作规范，引用就像判例被援引：援引不等于遵循。经典文献计量常用 citation count；但 “Smith (2019) argued that...” 与 “Smith (2019) is wrong because...” 在计数里完全相同。…
【锚点】我要拆的流行读法是：把【被引次数】当成一篇论文质量的近似。更准确地说，被引次数是【可见性×时间×网络位置】的汇总，不是质量；而真正能看见知识结构的是【co-citation 同引】。 【显式】被引次数 =…
