社会化标签应用已经成为人们组织和分享信息资源的重要手段。在用户标注信息资源过程中，用户是如何使用具有不同流行性的标签进行标注的，这些不同流行性的标签使用是否与用户的活跃度和资源的受关注度有关，这些问题的回答不管是对于标注资源的用户在标注资源时的标签选择，还是对于社会化标注应用的服务商提高服务质量都具有现实意义。

我们从用户的标注行为出发，以标注次数来区分标签的流行性、用户的活跃度和资源的受关注度，在构建用户、资源和标签的超网络基础上，定义了该超网络的超度及其分布、余平均超度和超度条件概率分布等指标，利用来自Delicious的数据展开研究。通过研究发现用户在标注过程中倾向于同时使用个性化标签和流行性标签对资源进行标注，且使用个性化标签的个数往往多于流行性标签的个数。此外用户的活跃度和资源的受关注度也与用户选择不同流行性标签具有相关性。而这些现象和规律的出现与不同流行性标签的功能以及用户的标注动机紧密关联。据此可以为不同类型的用户在标注不同资源时该如何使用不同流行性的标签以及社会化标注应用服务商如何根据用户和资源特性的不同提供标签服务提出更好的建议。

Thispaper focuses on exploring theusage patterns and regularities of coemploymentof various popular tags andtheir relationships with the activeness of users and the interest level ofresources in social tagging. A hypernetwork for social tagging is constructed,in which a tagging action is expressed as a hyperedge, and the user, resourceand tag are expressed as nodes. Quantitative measures for the constructedhypernetwork are defined, including the hyperdegree and its distribution, theexcess average hyperdegree and the hyperdegree conditional probabilitydistribution. Using the dataset from the Delicious, an empirical study is conducted.The empirical results show that multiple individual tags and one or a very fewpopular tags are generally employed together in one tagging action, and theusage patterns and regularities of tags with varying popularity are correlatedto both user activity and resource interest. The empirical results are furtherdiscussed and explained from the perspectives of tag functions and motivations.Finally, suggestions regarding the usage of various popular tags forboth tagging users and service providers of social tagging are given.
