可视化就是把数据、信息和知识转化为可视的表示形式的过程。一般来讲,可视化可分为数据可视化、科学计算可视化、信息可视化和知识可视化。可视化可以看做是人类与计算机这两个信息处理系统之间的一个接1:3单元。本文在给出可视化定义基础上,简要介绍了国际近年出现的可视化分析学情况,讨论了可视化在数据挖掘、复杂网络等领域的应用。最后指出了可视化研究存在的问题和重要发展方向。
Visualizations is a process that transform data, information and knowledge into a visual representation. Visualizations provides an interface between the human and computer information processing system. Data visualization, scientific visualization, information visualization and knowledge visualization is reviewed, then the emerging visual analytics and the visualization applications in data mining and complex network is discussed. Finally, the visualization problems are discussed.
