摘要
文本可视化是数据可视化的新兴主题,其目的是让人直观地认识数据,敏捷地发现数据中隐藏的规律。首先介绍了文本可视化的过程,包括信息收集、预处理、视觉呈现和交互功能等;然后通过分析和使用各种中文文本可视化的工具,从基于标签云、树图、关联和时间序列等多方面研究可视化技术;最后对比了这几种技术的差异和优缺点,并指出各技术的适用场景。文本可视化能够更好地帮助用户处理日益增长的文本信息,提高数据的可视化效率和转换成利益的效率。
The text visualization process was introduced at first,including information collection,preprocessing,visual presentation and interactive functions.Then based on the analysis of various Chinese text visualization tools,the visualization technology areas such as multi-based tag cloud,tree map,association and time sequences were researched.At last,the advantages and disadvantages of these techniques were compared from a few aspects and the various technologies applicable to the scene were pointed out.Text visualization can help users to better deal with the growing text information to improve the efficiency of data visualization and converted into efficiency benefits.
