社会标签系统中的自组织

Self-organization in social tagging systems

Chuang Liu, Chi Ho Yeung, Zi-Ke Zhang

摘要:

个体之间往往相互模仿,从而形成典型群体,从而形成群体中典型行为的自组织状态。在本文中,我们在社会标签系统的自组织模型,并说明了潜在的相互作用和动态。具体来说,我们引入了一个模型,其中个人调整自己的标记倾向,模仿平均标记倾向。我们发现,当用户的信心低,他们倾向于模仿别人,并导致一个自组织的状态与积极的标签。另一方面,当用户具有高信心并且对改变顽固时,标记变得不活跃。我们观察到一个相变在用户的信心,当系统从一个政权改变到其他的临界水平。将该模型得到的杆长分布与实际数据进行了比较,结果表明两者吻合较好。

英文摘要:

Individuals often imitate each other to fall into the typical group, leading to a self-organized state of typical behaviors in a community. In this paper, we model self-organization in social tagging systems and illustrate the underlying interaction and dynamics. Specifically, we introduce a model in which individuals adjust their own tagging tendency to imitate the average tagging tendency. We found that when users are of low confidence, they tend to imitate others and lead to a self-organized state with active tagging. On the other hand, when users are of high confidence and are stubborn for changes, tagging becomes inactive. We observe a phase transition at a critical level of user confidence when the system changes from one regime to the other. The distributions of post length obtained from the model are compared to real data which show good agreements.
