摘 要: | Folksonomy是Web2.0环境下一种有效的网络信息组织方式。本文分析了Folksonomy的网络性质,基于社会化书签系统delicious数据集,发现了标签网络具有的两个基本性质:(1)网络的平均最短路径为3.16,聚集系数0.63,远大于相同参数下的随机网络,这揭示了标签网络的小世界效应;(2)网络中标签的度大体上呈幂律分布,表明标签网络具有无标度特性。

Abstract: | Folksonomy is a new kind of information organization methods emerging in Web2.0 environment.This paper analyzod network properties of folksonomy. Based on the dataset of social bookmarking site delicious, two fundamental characteristics were discovered. ( 1 ) Average node degree was 3.16 and clustering coefficient was 0.63, which exhibited a typical small world effect. (2) The degree distribution of tag network followed a power law distribution, i.e., the scale free property. |
