协作标注与符号学动态
Collaborative Tagging and Semiotic Dynamics
摘要：
协作标记已经迅速获得了地面，因为它能够招募网络用户的活动，以有效地组织和共享大量的信息。在这里，我们从一个流行的系统收集数据，并调查标签共现的统计特性。我们引入了一个随机模型的用户行为体现两个主要方面的协同标记：（一）一个频率偏置机制的想法，用户暴露在对方的标记活动;（二）记忆的概念-或老化的资源-在形式的重尾访问系统的过去状态。值得注意的是，我们简单的建模能够定量地解释所观察到的实验特征，具有令人惊讶的高精度。这指向了用户的普遍行为的方向，尽管他们自己的认知过程很复杂，他们的标记活动具有不协调和自私的性质，但他们似乎遵循简单的活动模式。
英文摘要：
Collaborative tagging has been quickly gaining ground because of its ability to recruit the activity of web users into effectively organizing and sharing vast amounts of information. Here we collect data from a popular system and investigate the statistical properties of tag co-occurrence. We introduce a stochastic model of user behavior embodying two main aspects of collaborative tagging: (i) a frequency-bias mechanism related to the idea that users are exposed to each other's tagging activity; (ii) a notion of memory - or aging of resources - in the form of a heavy-tailed access to the past state of the system. Remarkably, our simple modeling is able to account quantitatively for the observed experimental features, with a surprisingly high accuracy. This points in the direction of a universal behavior of users, who - despite the complexity of their own cognitive processes and the uncoordinated and selfish nature of their tagging activity - appear to follow simple activity patterns.
