Abstract

The invention belongs to the field of user behavior prediction, and relates to a method and device for predicting the propagation trend of microblog rumors or / and rumor refuting topics. The method comprises the steps of obtaining data source information participating in a microblog rumor topic or / and a rumor refuting topic, and extracting related attributes; constructing an influence function by using a multiple linear regression algorithm; constructing a game strategy for forwarding rumor information and rumor refuting information, establishing a rumor and rumor refuting mutual influence model, and calculating the mutual influence of rumor and rumor refuting; mapping the user node to a pixel space based on a representation learning method, constructing a user forwarding image at the current moment, and predicting the user forwarding image at the next moment by using a convolutional neural network; fusing the mutual influence with the image forwarded by the user at the next moment, establishing a logistic regression prediction model, and predicting whether the user participates in a rumor topic or / and a rumor refuting topic at the next moment; according to the method, the propagation trends of the microblog rumor topics and the rumor refuting topics can be effectively predicted, and public opinion control and processing are facilitated.

Description

technical field [0001] The invention belongs to the field of network public opinion analysis, and relates to user forwarding analysis technology, in particular to the analysis of co-propagation of rumors and rumor refuting information in social networks, and specifically relates to a method and device for predicting the propagation trend of Weibo rumors or / and rumor refuting topics. Background technique [0002] Rumors have existed since ancient times. Traditionally, rumors are spread by word of mouth from person to person, with slow speed and small scope. With the rapid development of the Internet today, social media such as WeChat, Weibo, and blogs have penetrated into every aspect of people's daily lives. The emergence of social networks has brought great convenience to people, but it also provides a channel for rumors to spread. It can spread between strangers in different regions and far apart through social networks, which means that the speed and reach of rumors can...
