The Application And Research Of Web Information Extraction Technology In The Graphical Stock Analysis System

The rapid developments of the stock market at home and abroad,attracts more and more people joining the stock market to investment.At the same time,the vast majority of the shares of people do not understand basic common sense,are unable to understand how the relationship between stock market and the national policy goes,and are not familiar with the basic information of the listed companies on the stock market,which is unable to correctly estimate the stock market trends,investment results are not ideal.In order to pass the simple mode of operation to provide accurate intuitive to the shareholder of the stock market information,provide the operator with the system using graphical form clear real-time stock index chart,helps the operator in the judgments of the stock market better.The following is the system in the process of building the core research direction and the innovation function.(1)collect the data and establish a system to clear the operation of the users needs,to determine the overall structure of the system,and construct the concept of basic functional modules and database model.It design and implement that data acquisition,graphic display,information display and smart stock selection,and other functions(2)determine the stock information collection channels,namely full search the Internet and all kinds of securities system,through the Web page extraction technology and some regular expression form of information extract relevant information.(3)when it is concluded that the corresponding charts,the main use of GDI + technology,at the same time,in order to well coordinate system transformation,and improve the speed of K line drawing,the system also provides Graphics transformation matrix and bitble technology.Using this system,people can more clear and accurate grasp of stock information,predict the stock market development.At the same time,in order to make the system to provide the data more accurate,But still in the aspect of data extraction and data analysis have greatly improve space,still need further study and analysis,in order to improve the correctness of the data analysis.
