摘要 通过收集整理图书漂流(bookcrossing)网站一个月内的图书漂流信息,建立图书与用户的数据库模型,并且构建两者间关系的二分图。从复杂网络的角度分析计算该网络的相关参数,如度分布、聚集系数、平均最短路径、节点项目度、项目大小、点强度及节点兴趣度,得到的图书漂流网络模型同时具有无标度特性和小世界网络的特性。 By collecting the data of bookcrossing website as data source in one month,this paper constructed the database model of books and the users,and then structured the bipartite graphs to describe the relationship between them.From the perspective of complex network,this paper analyzed and calculated the network related parameters,such as degree distribution,clustering coefficient,the average path length,node strength distribution,act degree distribution,act size distribution and node interest,and the conclusion is that the book-crossing network model has scale-free characteristics and small-world network characteristics in the same time.
