摘要
词云是一种近年来颇为流行的文本可视化方式,它提取出文本中的关键词并在二维空间上美观地排布,通常用于展示文本内容、辅助文本分析以及吸引读者阅读等.从视觉编码、布局方法和交互方式这3个方面介绍词云的设计空间;将现有的词云设计分为语义词云、形状词云、可编辑词云和多文档词云4类进行概括,并总结了目前对于词云进行实验评价的若干工作;最后分别从语义词云、形状词云、多文档词云和中文词云4个方面分析了词云可视化领域面临的挑战,并对未来工作进行了展望.
Word cloud is a popular text visualization technique that extracts keywords from text and displays them on the 2D space aesthetically.Word cloud is often used to display contents,aid text analysis and attract readers.In this work,the design space of word cloud is introduced from three aspects:visual encoding,layout and interaction.Then current word cloud design researches are summarized by four categories:semantic word clouds,shape-constrained word clouds,interactive word clouds and multi-document word clouds.Several works related to word cloud evaluation are also concluded.Finally,research challenges in semantic word clouds,shape-constrained word clouds,multi-document word clouds and Chinese word clouds,and suggest future work of word cloud visualization are discussed.
