GRID: Graph Representation of Intelligence Data for Security Text Knowledge Graph Construction

In three linesGRID is an end-to-end framework for constructing security knowledge graphs from cyber threat intelligence articles. Using Qwen3-4B-Instruct, it combines graph extraction, text revision, and a task bank (multi-choice questions + regex) to generate stable rewards. On 249 CTI articles, the Task-bank Reward model achieves 84.62% precision, 64.91% recall, and 68.53% Avg F1.
