The invention particularly relates to a false news detection method based on large
language model cognition enhancement, which comprises the following steps of: constructing a user portrait model and a personality characteristic model by a
cognition-based comment generation module, interacting the user portrait model and the personality characteristic model with a large
language model, and generating a personification comment conforming to a user
cognition mode; the multi-view comment learning module is used for extracting semantic, emotion and style characteristics from the generated anthropomorphic comments, analyzing the consistency and inconsistency of the comments and news contents based on a large
language model, and generating a comment summary; the expert intelligent automatic screening module is used for guiding a large language model to generate expert opinions matched with the news samples through an experience matching strategy and
a domain enhancement strategy; and the interactive fusion and classification module fuses the news content, the comment summary and the expert opinions, and outputs the news authenticity probability through a cross attention mechanism and a classifier. Through the design of a plurality of modules, the accuracy and robustness of false news detection are improved.
