Embodiment Construction

[0023] The present invention will be further described below in conjunction with the accompanying drawings.

[0024] by figure 1 As an example, the propagation tree optimization problems based on breadth-first and depth-first based on consistent standpoints are introduced successively. figure 1 The structure tree diagram of rumor propagation in some original social media, figure 2 and image 3 The tree diagrams of the social media rumor propagation structure after applying the propagation tree optimization methods based on breadth-first and depth-first respectively. In the present invention, it is intended to propose a propagation tree optimization algorithm based on consistent standpoints applied to social media rumor detection scenarios, including a breadth-first-based propagation tree optimization method and a depth-first-based propagation tree optimization method, which can greatly reduce Propagate the number of branches and nodes in the tree, thereby reducing the comp...

Abstract

The invention belongs to the technical field of authenticity of social media information release, and particularly relates to a rumor propagation tree structure optimization method based on site consistency. For a top-down recurrent neural network model rumor detection scene based on a tree structure in social media, nodes with a same standing field in a rumor propagation tree structure can be merged into a super node. Standing field representation of the node to father nodes of the node is enhanced, the propagation tree structure is optimized, and rumor detection performance is improved. Thenumber of branches and the number of nodes in the propagation tree can be greatly reduced, so that the calculation time complexity of rumor detection is reduced, and the rumor detection performance isoptimized.

Description

technical field [0001] The invention belongs to the technical field of authenticity of social media information release, and in particular relates to a rumor propagation tree structure optimization method based on consistent positions. Background technique [0002] Rumors are generally defined as information that arises and spreads among people of unproven truth value or is deliberately false. The spread of rumors has been further facilitated in recent years as the popularity of social media on Twitter, Facebook, etc. has enabled unreliable sources to spread a lot of unverified information among people. Therefore, it becomes even more important to track and debunk rumors in real time. However, traditional feature-based methods extract features from the statistical information of fake news, the author of the message and their responses, and form a flat feature vector for rumor detection. However, this method ignores the propagation structure of the message, which leads to t...
