王子文献的识别指标构建

Identification Index of Princes

[目的/意义]王子文献的准确识别有助于睡美人论文唤醒机制的研究,而前人的研究缺乏对王子文献识别方法的探索。为完善王子文献识别体系,该文提出了一个识别王子文献的客观指标——Pr指数,又称“王子系数”,通过量化标准来衡量王子文献,以减少主观识别带来的误差。[方法/过程]在前人研究的基础之上提取王子文献的基本特征,综合施引文献与“睡美人”唤醒年的时间跨度、施引文献与“睡美人”的同被引次数和自身被引频次3个参数构建Pr指数。选取WOS"information science&library science"领域1998-2007年间发表的4篇睡美人的565篇施引文献为研究对象。根据王子文献识别框架,计算施引文献的Pr指数并检验识别效果。[结果/结论]通过识别结果的分析发现:Pr指数对王子文献具有较强的敏感性,能够显著区分出王子文献,且识别出的王子文献特征明显,对睡美人的唤醒有着显著的牵拉作用,识别效果较好。

[Purpose/Significance]Accurate identification of prince literature will be help for studying on awakening mechanism of"Sleeping Beauties",but previous studies lack the exploration of prince literature identification methods.In order to perfect the prince literature identification system,this paper proposes an objective index-Pr index,also known as"prince coefficient",to measure the prince literature by quantitative criteria.[Method/Process]The authors have extracted three basic characteristics of princes on the basis of previous studies.Pr index was constructed by synthesizing three parameters:time span from citing literature publication year to"sleeping beauty"wake-up year,co-citation frequency of citing literature with"sleeping beauty"and citing literature's self-citation frequency.The 565 publications having cited one of 4 Sleeping Beauties articles published in the ISLS field from 1998 to 2007 were selected as research objects.Then,the authors calculate the PR index of these publications and test the identification effect.[Result/Conclusion]Experimental results show that this method of Pr index has a strong sensitivity to prince literature and identifies effectively prince literature,with a significant pulling effect on the awakening of sleeping beauty.
