天文学论文的作者越多被引用的次数越多吗?

Are astronomical papers with more authors cited more?

K. Z. Stanek

摘要:

在我之前的研究论文长度与天文学引用数量(Stanek 2008)之后,一些同事表示有兴趣了解天文学论文的引用和作者数量之间是否存在任何相关性。至少天真地认为,作者越多的论文被引用的次数越多。我用Stanek(2008)分析的相同论文样本来检验这一预期,选择了2000年至2004年之间发表的A&A,AJ,ApJ和MNRAS的所有(约30,000)篇参考论文。(...)我发现,作者越多的论文平均被引用次数越多,但也只是微弱地增加:粗略地说,作者人数增加10倍,引用次数就会增加一倍。2位作者的论文被引用的中位数是17,而10到20位作者的论文被引用的中位数是32。我发现大部分的论文都是由少数作者撰写的,模式为2位作者,中位数为3位作者。我还发现,作者多的论文并不比作者少的论文长,事实上,对于任何数量的作者,每篇论文的中位数都是8到10页。对于相同的论文样本,每篇论文的引用中位数从2008年6月的15(Stanek 2008)增长到2009年11月的19。与Stanek(2008)不同,我不会以任何职业建议作为结论,半幽默或其他。

英文摘要:

Following my previous study of paper length vs. number of citations in astronomy (Stanek 2008), some colleagues expressed an interest in knowing if any correlation exists between citations and the number of authors on an astronomical paper. At least naively, one would expect papers with more authors to be cited more. I test this expectation with the same sample of papers as analyzed in Stanek (2008), selecting all (~30,000) refereed papers from A&A, AJ, ApJ and MNRAS published between 2000 and 2004. (...) I find that indeed papers with more authors are on average cited more, but only weakly so: roughly, the number of citations doubles with ten-fold increase in the number of authors. While the median number of citations to a 2 author paper is 17, the median number of citations to a paper with 10 to 20 authors is 32. I find that most of the papers are written by a small number of authors, with a mode of 2 authors and a median of 3 authors. I also find that papers with more authors are not longer than papers with fewer authors, in fact a median number of 8 to 10 pages per paper holds for any number of authors. For the same sample of papers, a median number of citations per paper grew from 15 in June 2008 (Stanek 2008) to 19 in November 2009. Unlike Stanek (2008), I do not conclude with any career advice, semi-humorous or otherwise.
