摘要: 背景:随着城市的发展和信息的爆炸式增长,产生了大量与POI有关的带有地理标签的纹理数据。从这些数据中提取有用信息并检测其空间分布是一个具有很大挑战性的问题。 创新:这篇文章提出了一种可视设计,将城市地铁线路与文本可视化的wordle方法有机结合起来,可以对城市中大量的地理位置及其语言信息进行有效的可视化,使用户可以有效的检索和选择目的地。在这个可视化中,我们利用地铁线将城市划分成几个分区,同时设定每个分区内的wordle的边界。wordles是从各POIs的文本信息中提取的关键字(包括评论、描述等)生成的,并且根据它们的地理位置被嵌入到各个分区中。通过交互式可视化和直观的结果呈现来研究文本分布的模式,可以指导用户探索城市中与空间相关的特征并高效地检索某一位置。 应用:本文以中国上海的餐厅数据为案例实现了本方法。

Abstract:
With the development of cities and the explosion of information, vast amounts of geo-tagged textural data about Points of Interests (POIs) have been generated. Extracting useful information and discovering text spatial distributions from the data are challenging and meaningful. Also, the huge numbers of POIs in modern cities make it important to have efficient approaches to retrieve and choose a destination. This paper provides a visual design combing metro map and wordles to meet the needs. In this visualization, metro lines serve as the divider lines splitting the city into several subareas and the boundaries to constrain wordles within each subarea. The wordles are generated from keywords extracted from the text about POIs (including reviews, descriptions, etc.) and embedded into the subareas based on their geographical locations. By generating intuitive results and providing an interactive visualization to support exploring text distribution patterns, our strategy can guide the users to explore urban spatial characteristics and retrieve a location efficiently. Finally, we implement a visual analysis of the restaurants data in Shanghai, China as a case study to evaluate our strategy.
