Embodiment Construction

[0023] The present invention will now be further described in conjunction with the accompanying drawings and embodiments.

[0024] As an embodiment of the present invention, see figure 1 , its stock automatic matching classification method based on news data includes the following steps:

[0025] (A) Create a local database.

[0026] (B) Capture historical news data of at least one relevant stock from the outside world and store it in a local database. Sources of historical news data include mainstream news portals, announcements from relevant national departments, exchange transaction data, social networks, etc.; and then establish Corresponding stock serial number, and perform word segmentation and screening for each piece of historical news data, remove function words and some uninformative word segmentation, and extract keyword sequences related to individual stocks; assuming individual stock serial numbers are stock A, stock B, ... , stock N; the keyword sequence is key...

Abstract

The invention relates to a matching and classifying method and system for stock information, in particular to an automatic stock matching and classifying method and system based on news data. The automatic matching and classifying method is characterized by comprising the following steps: establishing a local data base; performing word segmentation and screening on historical news data, extracting key word sequences, constructing sequence models for individual share key word sequence correlation, calculating the correlation between the individual shares, and classifying stocks by combining a cluster analysis algorithm; and performing word segmentation and screening on real-time news data, extracting a real-time key word sequence, calculating sequences for real-time key word sequence correlation, and performing automatic matching with the sequence models for individual share key word sequence correlation. The automatic stock matching and classifying method and system adopt the stock key word sequence excavation technology based on the news data to achieve automatic classification of the stocks; the method is comprehensive, accurate, simple, convenient and feasible, and provides better investment reference for investors; and stocks with higher matching degree are given automatically aiming at breaking news events.

Description

technical field [0001] The invention relates to a method and system for matching and classifying stock information, in particular to a method and system for automatically matching and classifying stocks based on news data. Background technique [0002] Traditional Internet search engine technology uses specific keywords to mark website pages, and provides search results by matching user search keywords with webpage keywords. With the development of Web technology, a large number of pictures, blogs, and videos are published on the Internet every day. The extreme explosion of information makes it difficult to help people find the information they need through simple keywords. The emergence of recommendation engines has transformed the way users obtain information from simple keyword searches to more advanced and richer information discovery that is more in line with people's usage habits. By mining the correlation between web pages and user data, constructing keyword sequence...
