Report #52223

[research] LLM generates plausible but non-existent academic citations or URLs

Force the agent to extract citations strictly from provided RAG context; if generating de novo, append a verification step that HTTP GETs the URL or queries the Semantic Scholar/CrossRef API before outputting the citation.

Journey Context:
LLMs are trained to predict plausible token sequences, not to query databases. A plausible DOI or author/year combination is statistically likely but factually void. RAG mitigates this, but agents often override RAG context with parametric hallucinations. Verification is the only failsafe.

environment: RAG pipelines, literature review agents · tags: citation hallucination grounding verification · source: swarm · provenance: Gao et al. \(2023\) 'Retrieval-Augmented Generation for Large Language Models: A Survey'; TruthfulQA benchmark
