基于二次函数曲线拟合的睡美人文献识别研究

Recognition of Sleeping Beauty Articles Based on Quadratic Function Fitting

[目的/意义]为了弥补已有睡美人文献识别方法的不足,在前人研究的基础上,提出基于二次函数曲线拟合的识别方法。[方法/过程]利用Origin Pro的批量曲线拟合功能,对1998-2002年发表的图书情报领域的文献引文轨迹进行曲线拟合,通过观察函数曲线对称轴的位置识别睡美人文献,并分析其社会影响力和社会价值。[结果/结论]通过引文曲线和SC、WC、LC等指标的对比分析,发现相对K指标识别方法,提出的睡美人文献识别方法更能体现睡美人文献的特征,为睡美人文献的识别提供了新的研究思路,是对睡美人文献识别方法的丰富与拓展。

[Purpose/Significance]In order to make up for the downsides of the existing methods of sleeping articles,this paper proposes a recognition method based on quadratic function on the basis of predecessors＇ research.[Method/Process]Using Origin Pro ＇s batch curve fitting function,the document citation trajectory of Library and Information Science published in 1998-2002 is curve-fitted.By observing the position of the symmetry axis of the function curve,the sleeping beauty literature is identified and its influence and social value are analyzed.[Result/Conclusion]Through the comparison and analysis of citation curve and SC,WC,LC and other indicators,we find that the citation curve corresponding to K index is better to reflect the characteristics of sleeping beauty articles. Based on the quadratic function method,it provides a newresearch idea for the identification of sleeping literature.It is the enrichment and development of the method of recognizing the articles of sleeping beauty.
