一个多世纪以来《物理评论》的引文统计

Citation Statistics From More Than a Century of Physical Review

S. Redner

摘要:

我们研究了1893年至2003年110年期间所有《物理评论》期刊的引文统计数据。除了表征引文分布和识别具有最高引文影响力的出版物外,我们还研究了引文如何随时间演变。论文被引次数与被引平均年龄呈正相关。来自出版物的引用具有指数衰减的年龄分布;也就是说,旧论文往往不会被引用。相反,对出版物的引用符合幂律年龄分布,在2 - 20年的时间范围内指数接近-1。我们还确定了一些强相关的引用突发和其他戏剧性的特点,在引用的时间历史,以个别出版物。

英文摘要:

We study the statistics of citations from all Physical Review journals for the 110-year period 1893 until 2003. In addition to characterizing the citation distribution and identifying publications with the highest citation impact, we investigate how citations evolve with time. There is a positive correlation between the number of citations to a paper and the average age of citations. Citations from a publication have an exponentially decaying age distribution; that is, old papers tend to not get cited. In contrast, the citations to a publication are consistent with a power-law age distribution, with an exponent close to -1 over a time range of 2 -- 20 years. We also identify a number of strongly-correlated citation bursts and other dramatic features in the time history of citations to individual publications.
