社交媒体数据可视化分析综述

社交媒体的出现为人类提供了新的交流方式，同时也产生了大量的数据。这些数据蕴含着丰富的信息，也反映了人类的社会行为。利用可视化分析技术可以对社交媒体数据进行交互式分析，提高人类对抽象信息的理解和综合研判能力。本文首先介绍了可视化分析的步骤。在此基础上，阐述了社交网络可视化、时空信息可视化和文本可视化的实现方式。最后，对可视化分析过程中遇到的问题和挑战进行了讨论。

An Overview on Social Media Visual Analytics

The emergence of social media provides a new way of communication for human beings, and the everyday usage of social media results in big open social media data. The data offer fruitful information and reflect social behaviors of people. It can be analyzed interactively by using visual analytics. As a result, the ability of human beings can be improved by better understanding abstract information and making a comprehensive judgment. Firstly, we introduced the steps of visual analytics. We further explained the implementation methods of social network visualization, spatial temporal information visualization and text analysis visualization. Finally, we discussed the problems and challenges encountered in the visual analysis process.
