XGRAG: A Graph-Native Framework for Explaining KG-based Retrieval-Augmented Generation
A framework that generates causally grounded explanations for GraphRAG systems.
The paper introduces XGRAG, a graph-native framework for explaining knowledge graph-based retrieval-augmented generation. It employs graph-based perturbation strategies to quantify the contribution of individual graph components on the model answer. The authors conduct experiments comparing XGRAG against an existing explainability baseline and evaluate its robustness across various question types and LLMs.
