Critical node identification for emergencies

Abstract

The rapid identification of key nodes in large-scale social networks is important for the guidance and control of public opinion. The model proposes a key node identification method that considers user attributes, behavioural attributes, historical text attributes, user expertise and rationality values. Compared with methods that only consider user attributes, behavioral attributes and historical text attributes, this method can identify key nodes more quickly. Limitations: This method cannot identify key nodes in the network in real time.
