基于引文曲线导数的睡美人文献识别研究

Research on Sleeping Beauty Document Recognition Based on Citation Curve Derivative

文章借鉴微分学中的导数概念,提出利用引文导数对睡美人文献进行识别,以丰富识别睡美人文献的方法体系。选取WOS"information science & library science"领域1998—2003年发表的7553篇期刊文献为研究对象,利用Origin的微分功能计算其引文导数,识别其中的睡美人文献。通过对比实验发现,与被引速率相对比,引文导数对具有高影响力、深度睡眠、觉醒强度大的睡美人文献具有更好的识别效果。

Based on the derivative concept in differential calculus,this paper proposes to use the citation derivative to identify the sleeping beauty literature,so as to enrich the method system for identifying the sleeping beauty literature.The 7553 journal articles published in the field of WOS'information science&library science'from 1998 to 2003 were selected as the research objects.The derivative function of Origin was used to calculate the citation derivatives and identify the sleeping beauty literature.Through comparison experiments,it is found that compared with the rate of citation,the citation derivative has a better recognition effect on the sleeping beauty literature with high influence,deep sleep and strong arousal intensity.
