高引论文与Ref.之间的相关性

根井正利,田村浩一郎的高引论文,特别是关于分子进化遗传学分析(MEGA,全称Molecular evolutionary genetics analysis)软件研究的相关论文与Ref.的相关性进行统计,结果显示:论文被引频次与Ref.之间呈现出负相关,并非参考文献数越多,论文的被引频次就会越高。

由表1可知,Ref.与论文被引频次的相关性无论是Google学术搜索的被引频次统计结果,还是AMinerScopus以及Web of Science的被引频次统计结果均表现出相关性差,而且有负相关出现;但是,Google学术搜索的被引频次统计结果与AMinerScopus以及Web of Science的被引频次统计结果之间的相关性均在0.99以上,在p=0.05的水平上,双尾检验结果显示出显著性相关。

不同数据库Ref.与论文被引频次的相关性统计结果

不同数据库Ref.与论文被引频次的相关性统计结果表明,除了相关性差的共同特点之外,就是有随着Ref.数量的增加,论文被引频次反而有下降趋势。
