More and more users are enthusiastically involved in the discussion of hot topics in social media, and user-generated content can quickly reach a wide audience due to the convenience of the platform and the like. However, a great amount of false information is generated and spread in social media, which brings harm to social stability and seriously affects the daily life of people and the healthy development of society. Therefore, how to automatically detect false information is an urgent research subject in the field of social network analysis, and has important research significance and practical application significance.
Over time, the source blog forms its particular propagation structure through a series of forwarding or replying to propagation relationships. Existing studies have found that spurious information presents a faster, wider, deeper propagation structure than real information. These structural features provide the opportunity for researchers to detect false information using the propagated data. With the development of Deep Learning (Deep Learning), data Mining (Data Mining) and Graph Learning (Graph Learning) technologies, many methods model propagation Data of source blog text into a tree structure or a Graph structure, learn feature representations of the source blog text by using a Deep Learning tool, and construct a classifier for detection.
