在线书签系统中标签分布特性的仿真研究

摘要

在线社会化书签的出现迎合了用户的需求,并给人们带来了很大的方便.采用目前最流行的Delicious系统中的标签作为对象,研究其分布特性,试验结果表明标签的分布也服从幂率分布,具有胖尾的幂律分布的特征,说明如同社会环境中人类行为,互联网环境下的标签也具有类似的动力特性.%The online social bookmarks systems not only meet users' needs and also bring great conveniences.This paper studies the distribution characteristics of tags attached bookmarks which are popular in Delicious systems.The results show that the tags of online bookmarking systems follow the power-law distribution of fat tails, explain that tags also have similar dynamic characteristics as the human behavior in the social environment.
