信息可视化是常用的数据挖掘方法之一，它通过把海量的数据转化成可视化的形式让人们更容易观察、浏览和理解信息，并且找到数据中隐藏的模式。目前，国家已经建立海量的科技文献资源，但仅限于查询、浏览、全文传递等服务，没有得到充分的开发利用。本文介绍了利用信息可视化技术科技文献资源进行深度挖掘的方法，并介绍了一种监测模型CiteSpaceⅡ，它可以对科技文献中涌现的趋势和临时模式进行监测和可视化。最后总结出了利用信息可视化技术对科技文献资源进行深度挖掘的一般步骤和常用的开发工具。

Information visualization is commonly used method of data mining, which transform mass data into a visual form enabling the viewer to observe, browse, understand the information and find some models hidden in data easily. At present, there are mass literature resources which only serve for search, explore and fuN-text transfer, not developed and utilized fully. This paper introduce the method of using information visualization technology to mine science and technology resources, and describe a model CiteSpace Ⅱ , which can detect and visualize emerging trends and transient patterns in science and technology literature. According to this, the general procedures and tool of mining science and technology literature deeply are summarized.
