Abstract

The invention relates to an automatic stock selection method based on big data of news. According to the technical scheme, firstly, emotional vocabularies and industry vocabularies which come from a professional Chinese Financial Dictionary are stored in a storage; internet financial news are acquired in real time through RSS and updated every half hour; news text content of the day is analyzed through a server, text analysis of the news content comprises two sub-sections: 1) emotional dimension analysis of the news content: emotional tendency of the news content is obtained through calculation; 2) industry dimension analysis of the news content: industry attention embodied by the news content is obtained through calculation.
