对情报学1991至2007近16年来发表的17,000篇文献进行统计分析,检验其文献著者是否服从广义洛特卡分布。通过对合著作者的处理和高产作者的删除,得到相对应的学科参数,并分析各种方法之间的优劣以及洛特卡定律在大样本检验时存在的问题。
A statistical analysis of 17,000 articles published in Information Science from 1991 to 2007 in the past 16 years was conducted to examine whether their authors obey the generalized Lotka distribution. Through the co-author’s treatment and deletion of high-yield authors, the corresponding disciplinary parameters are obtained, and the merits and demerits of the various methods and the problems existing in the large sample test of Lotka’s law are analyzed.
