摘要随着互联网的发展，Web2.0网站为互联网用户的信息生成、信息共享及信息获取提供了便利的平台。用户已经从过去的被动接受信息转变到现在的主动发布信息，产生了许多的用户生成内容，标签就是其中的一种。标签可以用于Web 资源的自动分类、信息检索、信息推荐等不同应用场合，用户可以根据自己的意愿给标注对象添加标签，而标签多采取自由标引方式，部分标签并不能有效地揭示资源的内容或主题，就产生了许多低质量的标签，干扰了社会标注系统中资源组织的秩序，降低了标签在应用场合中的质量和用户满意度。64307

本文首先从有关标签质量的文献出发，简要介绍现有标签质量评估的研究工作，同时对标签类型进行划分，根据以上的研究成果，设计了标签质量评测系统，用于用户对中文IT专业博客网的标签进行打分和标签类型选择，收集标签质量评估和标签类型分类用的训练数据集与测试数据集，为以后标签质量的评估提供数据支持。最后根据用户的评价结果对中文IT专业博客网的标签质量进行分析，并发现标签类型为内容相关的标签拥有很高的质量。
