The invention discloses a multi-
modal social network public opinion hidden danger
troubleshooting method and
system, and the method comprises the steps: collecting the multi-
modal data of a
social platform in real time through a distributed
edge node, and the multi-
modal data comprise text, image and audio data; dividing a plurality of
social network communities based on user interaction relationships, wherein the user interaction relationships include but are not limited to topic circles, friend relationships, comment interaction and forwarding likes;
community propagation dynamic features, group topological features and content features are extracted from the multiple
social network communities one by one based on the multi-
modal data; screening out a plurality of suspected hidden danger communities from the plurality of social network communities based on the
community propagation dynamic characteristics, the group topological characteristics, the content characteristics and a preset screening strategy; and after carrying out hidden danger detection and hidden danger classification on the plurality of suspected hidden danger communities based on the multi-
modal data, outputting a plurality of hidden danger classifications corresponding to the plurality of suspected hidden danger communities. According to the method and the
system, the comprehensiveness and the accuracy of public opinion hidden danger recognition are remarkably improved.
