LLM-Empowered Class Imbalanced Graph Prompt Learning for Online Drug Trafficking Detection (2025.findings-acl)
Copied to clipboard
| Challenge: | Existing approaches to combat illicit drug trafficking are impractical due to the scarcity of labeled samples and imbalance of classes. |
| Approach: | They propose a Large Language Model-empowered Heterogeneous Graph Prompt Learning framework for illicit drug trafficking detection that leverages LLM to facilitate heterogeneous graph neural networks to effectively identify minority classes. |
| Outcome: | The proposed framework is able to identify minority classes in class-imbalanced scenarios. |
