以网络计量学领域的网站链接数为基础,研究网址入链分布规律。首先,通过研究中网站之间的链接关系,选定入链数作为研究对象,并获取原始数据;接着,利用最小二乘法、K-S检验算法以及M.L.Pao教授提出的指数不为2时的逼近c值的估计公式对数据进行洛特卡定律拟合,发现网络计量学领域的网址入链分布并不服从洛特卡定律。最后,讨论造成不服从洛特卡定律的原因。
Based on the number of website links in the field of econometrics, this paper studies the distribution rules of URLs into web sites. First of all, through the study of the link between the Web site, selected into the chain as the research object and access to the original data; Then, using least squares, KS test algorithm and Professor MLPao index is not 2 when the approximation c The value estimation formula fitted Lotka’s law to the data and found that the distribution of URLs in network metrology did not obey Lotka’s law. Finally, discuss the reasons for not conforming to Lotka’s law.
