Information sorting retrieval system and method

Abstract

The invention relates to an information classification and retrieval system, which comprises a stock name classification database, an index association module and a news index database. The stock name classification database stores at least one stock name classification. The stock name classification also comprises a stock name, a stock code and a stock classification. The index association module is used for analyzing the key words related to stock in the news, finding out the stock classification corresponding to the key words in the stock name classification database, and building the index association between the news and the stock name classification. Afterwards, the news and the corresponding index association are stored in the news index database and the system can find out the consistent news in the news index database and transmit to the user terminal, thus having the advantages of shortening the time for news search, decreasing the calculation load of the user terminal and reducing the data transmission bandwidth.

Description

technical field [0001] The present invention relates to an information classification retrieval system and method, in particular to a method for shortening the time for retrieving news, reducing the computing burden on the user end, and reducing the bandwidth of data transmission by establishing an index association between news and stock names. An information classification retrieval system and method. Background technique [0002] With the rapid development of information technology, people's demand for real-time and convenient information acquisition and communication is still showing explosive growth. Portable wireless communication devices with various functions are constantly being developed in order to meet the convenience and needs of people's lives. For example, various mobile phones (or mobile phones, Cellular Phones), smart phones (Smart Phones), stock machines, and personal digital assistants (Personal Digital Assistants; PDAs for short) with mobile communicatio...

Problems solved by technology

Users have to find and filter the news they want to read one by one from these news data. Not only can they not provide the news that users really need in real time, but also waste the limited transmission bandwidth of wireless communication, and occupy a large amount of time.
