Web服务的本质如何驱动社会化标记中的词汇创建
How the nature of web services drives vocabulary creation in social tagging
摘要：
社交标签系统允许用户在共享资源上添加任意字符串，称为“标签”，以组织和管理信息。Yule-Simon过程已经显示出捕获社会标记行为的群体动态的能力，但它不处理新词汇创建的机制，因为它假设新词汇创建是一个泊松随机过程。在本研究中，我们着重从微观角度探讨词汇的生成机制，并讨论它是否也遵循Yule-Simon过程中假设的随机过程。为了捕捉词汇创造的微观机制，我们专注于在同一条目中使用的标签的数量和本地词汇创造率之间的关系。我们发现，这种关系不是一个简单的随机过程的结果，不同的服务。此外，这些差异取决于用户的标记态度是私人的还是开放的。这些结果提供了一个新的指数，以确定服务的内在性质的潜力。
英文摘要：
A social tagging system allows users to add arbitrary strings, called "tags", on a shared resource to organize and manage information. The Yule--Simon process, which has shown the ability to capture the population dynamics of social tagging behavior, does not handle the mechanism of new vocabulary creation because it assumes that new vocabulary creation is a Poisson-like random process. In this research, we focus on the mechanism of vocabulary creation from the microscopic perspective and discuss whether it also follows the random process assumed in the Yule--Simon process. To capture the microscopic mechanism of vocabulary creation, we focus on the relationship between the number of tags used in the same entry and the local vocabulary creation rate. We find that the relationship is not the result of a simple random process, and differs between services. Furthermore, these differences depend on whether the user's tagging attitudes are private or open. These results provide the potential for a new index to identify the service's intrinsic nature.
