论文引用历史:有时富人更富,有时他们不会

Citation histories of papers: sometimes the rich get richer, sometimes they don't

摘要:

我们描述了一个简单的模型,如何出版物的引用随着时间的推移而变化,基于纯出生的随机过程与线性累积优势效应。该模型被应用到引用数据从物理评论语料库提供的APS。我们的模型显示,论文分为三个不同的集群:具有快速初始引用和最终高影响力的论文(快速-hi),快速上升但快速达到平台(快速-平坦),或晚开花(缓慢-晚),这些论文可能从未获得过很多引用,或者在出版后多年。在“快-高”和“慢-晚”中,存在一种富-更富效应:有很多引用的论文更快地积累额外的引用,而“快-平”论文则没有显示这种效应。我们的结论表明,只需要几年的出版后的统计数据,以确定高影响力(“快喜”)的论文。

英文摘要:

We describe a simple model of how a publication's citations change over time, based on pure-birth stochastic processes with a linear cumulative advantage effect. The model is applied to citation data from the Physical Review corpus provided by APS. Our model reveals that papers fall into three different clusters: papers that have rapid initial citations and ultimately high impact (fast-hi), fast to rise but quick to plateau (fast-flat), or late bloomers (slow-late), which may either never achieve many citations, or do so many years after publication. In "fast-hi" and "slow-late", there is a rich-get-richer effect: papers that have many citations accumulate additional citations more rapidly while the "fast-flat" papers do not display this effect. We conclude by showing that only a few years of post-publication statistics are needed to identify high impact ("fast-hi") papers.
