In order to increase the efficiency of browsing and take the advantages of different type charts, the charts on page are interactive.This paper consists of three parts. The first part is about the requirement analysis of financial news hot information, news storage and data process. It includes the design of storage schema of financial news, and the data pre-processing based on whole application requirements. The second part aims at financial news hot information extraction. It includes the application of data mining methods based on intermediate data obtained from part one.The results of part two are part of the data for display. The last part is design and implementation of the final representation using data obtained in previous two parts.
