Knowledge Base Auditor
Software componentKnowledge & DataKnowledge & Dataarc:KnowledgeBaseAuditor
A curation component that periodically verifies knowledge base content against authoritative sources and validates source credibility, flagging inaccurate or unattributed entries.
Responsibility. Audits knowledge base accuracy and source credibility against authoritative references.
Also known as: Knowledge base quality assurance, Automated fact-checking of knowledge base, Cross-reference accuracy validation, Routine quality audit, Cross-reference validation

Design guidance
- SHOULD audit knowledge base content regularly (e.g., quarterly) against authoritative sources such as official filings.
- SHOULD admit only high-credibility sources into the knowledge base.
- SHOULD cross-check claims against authoritative external sources (official price lists, government databases, manufacturer specs) where ground truth is accessible.
- SHOULD remove or update stale documents, fix missing embeddings and deduplicate the corpus (Ref8.04).
Quantitative guidance
As stated by the sources; verify before use.
- A routine audit found 1.5% metadata errors in a legal research corpus after six months, costing over $500,000 in attorney review (Ch6.4 case study).
