摘要
针对新的可视化方法以及成熟的技术在不同类型数据方面的应用需要不断提出和创新的问题,提出了一种用桑基图来展现时间序列文本数据的可视化方法,并设计了相关的可视化算法。使用金融文本数据集对提出方法进行了验证,证明了方法的有效性。这种可视化方法能够对时间序列文本数据形象展现,对隐含的知识能够有效挖掘,具有很好的实用性。
For the problems of the new visualization methods and the mature visualization technology need to be put forward and innovate in the application of different data, this paper proposed a Sankey diagram method to show the visualization for textual data including of time series,and designed a related visualization algorithm. It tested and verified the effectiveness of the proposed method using specific financial textual data. The results show that this method can clearly express the textual data including of time series,can be conducive to mine the implicit knowledge effectively and has very good practicality.
