Abstract

The invention discloses a news authentication early warning method and system based on user generated content. The method includes the steps of obtaining reference data by conducting semantic extension on news clues; conducting oriented collection on the reference data so as to obtain information content, transmission modes, user groups and behavior information, attribute information and the like of the user groups, wherein the information content, the transmission modes, the user groups and the behavior information, attribute information and the like of the user groups are related to the news clues; conducting semantic knowledge extraction on the information content; conducting clustering and similarity calculation on semantic knowledge; recognizing the news clues which are not matched with a history news clue database; conducting credibility evaluation on the news clues on the aspects of semantic knowledge comparison, the user groups, the spreading modes, the information content and the like. Finally, the classified measurement and early warning of the UGC news authenticity are achieved, and the decision support is provided for judging whether news is true or not.
