The authors propose path pooling, a simple and plug-and-play method that introduces structure information through a novel path-centric pooling operation. This approach seamlessly integrates into existing KG-RAG methods, enabling richer structure information utilization.

Extensive experiments demonstrate improved performance with negligible additional cost.
