摘要 为了揭示科研人员网络文献采纳行为及相关变量概率分布的幂律渐近行为,选取了中文社会科学引文索引CSSCI(1998-2009年)情报学和图书馆学期刊发表文献中引证的网络文献作为数据样本,结果表明网络文献采纳行为存在集中现象,且与加菲尔德提出的文献引用集中定律较为一致;同时运用KS统计量和极大似然估计拟合幂律分布xmin值和a指数进行幂律分布检验,并通过非参数Bootstrap方法估计出xmin不确定性,其结果证明网络文献采纳频次服从幂律分布。 This paper is to examine the behaviors of web-based resources citation and Power-law of probability for researchers. Using Web-based resources cited by published papers of Information Science and Library Science extracted from Chinese Social Science Index as data sample, this paper applied Kolmogorov - Smirnov (KS) and maximum likelihood estimation to calculate Xmi. andafor Power-law test of cited frequency, and used Bootstrap to estimate uncertainty of Xmax The results demonstrate that there exists the phenomenon of concentration of web-based resources adoption, the laws of adoption are more consistent with Garfield' s Law of Concentration and Power -law distribution.
