[research] Generating plausible but non-existent URLs or DOIs for citations

Never generate URLs or DOIs from parametric memory; strictly enforce that any link must be directly extracted from retrieved context, and validate via an HTTP HEAD request before outputting.

Journey Context:
LLMs learn the structural patterns of academic identifiers \(e.g., arXiv IDs, DOI formats\) and confidently generate valid-looking but entirely fabricated links. Structural validity does not imply existence. RAG mitigates this, but only if the agent is rigidly constrained to copy strings rather than synthesize them.

environment: RAG · tags: citation grounding fabricated-links hallucination · source: swarm · provenance: Vectara Hallucination Leaderboard / Hallucinations in Large Language Models: A Survey \(Huang et al., 2023\)
