01Motivation

AI medical citations: can we trust them?

  • When a medical AI cites, one question decides trust: does the cited article really support the statement?
  • Existing systems answer without citations, or attach references that may not back the claim.
Without verifiable citations a clinician cannot check whether each statement is supported.

02Method

End-to-end citation generation and evaluation

  • A citation seeker re-retrieves and reranks the sources behind each generated statement.
  • An attribution judge then checks whether each cited article actually supports its claim.
