通过分析用户浏览网站的访问日志,建立用户.网站的二部图。其次分别通过对用户和网站进行投影,构建出用户网和网站网。然后通过计算节点间的相似度来确定边的权值。最后计算了用户网和网站网进行了度分布、平均最短路径、平均群聚系数、点强度等拓扑参数以及时间间隔分布等人类动力学特性。证实了该网络是无标度网络,且具有“小世界”效应特性。
The Bipartite network ofuser-website network is built by analysing the internet browsing history. Secondly, it builds two networks of users and websites by mapping the users and websites respectively. The value of edge is the similarity of two nodes. By calculating the topological parameters, including degree distribution, average shortest path length, average clustering coefficient and node strength, the conclusion is that both the network of users and network of websites are scale-free networks with small world effect.
