HEDGE: Hyperbolic-Enhanced and Dynamic Edge-Aware Graph Network for Social Bot Detection
- Published
- Record updated
Summary
HEDGE is a graph neural network for social bot detection that targets bots mimicking human behavior and injecting unreliable interaction edges. It combines a Hyperbolic Space Linear Transformation (HSLT) to model hierarchical user features, a variational graph auto-encoder with an edge feature optimizer, and a dynamic graph network that weights edges by reliability scores. The authors report that HEDGE outperforms 14 baselines on three real-world datasets.
