Graph Traversal Context Crucial for Citation Faithfulness in Agentic GraphRAG

A recent paper on arXiv (2605.15109) examines the concept of citation faithfulness in Agentic GraphRAG, where an agent navigates a knowledge graph prior to generating responses and citations. The research presents faithfulness as an issue at the trajectory level, emphasizing that final citations should reflect the graph's traversal, its structure, and entities that were visited but not cited. Through controlled ablation studies, it is revealed that while cited evidence is often essential—its absence significantly alters answers and diminishes accuracy—it is not solely adequate, as precise answers can also rely on the context of uncited traversals and the surrounding graph structure. Thus, the study indicates that citation assessment should encompass the full traversal context.
