Citation evaluation guide

How to evaluate AI citations claim by claim

How to check whether a cited passage supports the claim it sits on, and how to count the material claims in an answer that carry no citation at all.

Updated 21 Aug 2026

Definition

A citation does not prove an answer correct. Citation correctness asks whether a cited source supports the claim attached to it; citation completeness asks whether the material claims in an answer have adequate citations at all. They are separate measurements and a system can fail either one on its own.

01

Prepare reference questions

Write the expected evidence and acceptable behaviour before seeing system output.

  • Lookup and synthesis questions
  • Comparison questions
  • Absent-answer and conflict cases
  • Expected evidence written first
02

Split answers into material claims

Do not give an entire paragraph one score when its claims have different support.

  • Mark each factual proposition
  • Mark decision-relevant claims
  • No single paragraph score
03

Judge citation correctness

For each citation, inspect the source passage, document identity, version and context. Record supported, partially supported, contradicted, irrelevant or inaccessible.

  • Inspect the source passage
  • Check document identity and version
  • Record support or contradiction
  • Flag irrelevant or inaccessible
04

Judge citation completeness

Identify material claims without adequate supporting citations. Separate a missing citation from a cited passage that is itself weak.

  • Find material uncited claims
  • Check citation adequacy
  • Missing versus weak citation
05

Test difficult evidence

Include definitions, tables, footnotes, cross-references, amendments, stale versions and sources that disagree.

  • Correct source and version
  • Correct page or passage
  • Claim-level support
  • Material uncited claims
  • Conflict visibility
  • No-answer behaviour
06

Report counts, not a single score

Publish counts and rates only when the denominator, scoring rules, evaluator process and failed cases are available.

  • Publish the denominator
  • Publish scoring rules and process
  • Include failed cases
  • Keep correctness and completeness separate

What this page does not prove

  1. B1Citation presence is not citation correctness.
  2. B2A correct citation does not prove the answer is complete.
  3. B3Page highlighting depends on source parsing.
  4. B4Evaluation results apply to the tested document set and configuration.
