在对站间转移行为理论综述的基础上,基于齐普夫定律和复杂网络理论对站间转移行为的规律与特性进行了理论探讨与实证研究。研究结果表明站间转移行为具备下述规律与特性:特定和非特定任务环境下的访问者站间资源分配规律是一致的,符合齐普夫定律形式;访问者站间转移网络的度分布是非常不均匀的,但却并不服从幂律分布;具备小世界特征和高聚类系数,但总体结构是相对松散的;具备异类匹配特征,存在大量从大型网站向小型网站、从搜索引擎向小型网站的转移等异类匹配现象;具备对随机删除节点的高度鲁棒性和对topN删除节点的高度脆弱性。
Based on the review of the theory of transfer behavior between stations, the rules and characteristics of transfer behavior between stations based on Zipf’s law and complex network theory are discussed theoretically and empirically. The results show that the inter-station transfer behavior has the following regularities and characteristics: The resource allocation rules between the visitor stations in the specific and non-specific tasks are consistent and follow the Zipf’s law. The degree distribution of the inter-visitor station transfer networks is Very heterogeneous, but not obey the power law distribution; with small world features and high clustering coefficient, but the overall structure is relatively loose; with heterogeneous matching features, there are a large number of large sites from small sites, from search engines to Heterogeneous matching such as the transfer of small websites; with high robustness to randomly deleted nodes and high vulnerability to topN deleted nodes.
