摘　　要：【目的】为了更好地分析大众标注的语义关系,以层次可视化的方式增强用户感知。【应用背景】大众标注可以从普通用户的角度很好地反映网络资源的意义。层次信息可视化技术作为一种有效的表现抽象信息的工具,被广泛应用于辅助用户认知和分析层次数据集。【方法】提出五元组描述大众标注的语义的方法,借用归类方法使大众标注具有层次关系,基于层次结构提出信息可视化方法,用于显示大众标注集。【结果】实验表明,该方法可以清晰直观地揭示大众标注的层次关系,改善平面布局,而其他语义关系存储在大众标注节点中,不直接干扰用户感知。【结论】该方法简单有效,能够从优化整体布局的角度可视化层次信息,增强用户感知能力。[Objective] Hierarchy visualization is an intuitional way to analyze semantic relations between Folksonomies by enhancing users＇ cognition. [Context] Folksonomy reflects the meaning of Web resources well from the perspective of the common users. Hierarchy information visualization technology, as a precise tool of representing abstract information, is widely used to assist users to cognize and analyze hierarchy data set. [Methods] Firstly, a five-tuple method is improved to describe the semantics of Folksonomy. Secondly, the paper uses an existing classification to make the Folksonomies have hierarchy relations. At last, it puts forward an information visualization algorithm to display the Folksonomy set based on hierarchy structure. [Results] Experiments show that it reveals represents hierarchy relations of Folksonomies clearly and intuitively, improving the layout effectively. Other semantic relationships are stored in Folksonomy node for less influence on users＇ cognition. [Conclusions] It is proved to be an effective and simple way to visualize hierarchy information from the perspective of optimizing the overall layout and enhance the ability of user cognition.
