Feedback-Assisted Trust Propagation over Document Relation Graphs for Retrieval-Augmented Generation

Read the original on arXiv AI →

The paper introduces TrustPropRAG, a method that builds a document relation graph to propagate reliability signals across documents in retrieval‑augmented generation systems. By anchoring this propagation with a limited set of human feedback on document reliability, the approach estimates trust scores through an optimization problem that incorporates pairwise relations and user input. These trust scores are then used to select more reliable documents and generate answers that are aware of document trustworthiness, leading to improved retrieval quality and exact match performance compared to baselines, even with sparse or noisy feedback.

ReliableRAG: Combating Misinformation in Retrieval-Augmented Generation via Reliability-Guided Reasoning Chains

ReliableRAG is a new framework for Retrieval-Augmented Generation that tackles misinformation in multi‑hop question answering. It extracts structured triples from retrieved documents, evaluates each triple’s reliability by combining semantic relevance to the query with credibility, and keeps only the top‑K reliable, non‑redundant triples. Using these refined triples, the system builds robust reasoning chains that filter out deceptive misinformation and produce accurate, trustworthy answers.
