Stale Knowledge Bases: When Policies Change but Search Still Hits Old PDFs, Agents Confidently Err

Veröffentlicht: 2025-06-06 Quelle: 许愿牛科技

Policies change while retrieval still ranks old PDFs—agents cite expired clauses with confidence. Knowledge needs effective dates, retirement, and a single current version.

Policies get a new version while old PDFs stay in the library—and retrieval still ranks them high. Agents cite expired clauses with confidence; the floor follows old rules. Knowledge must carry effective dates, retirement, and current-version flags. Q&A may only use current documents. Expired files may archive for reference—not default search.

Old PDFs are not harmless museum pieces. To the model, they are still on-duty policy.

Only One Current Version

Each policy gets one current ID. Revisions retire old retrieval entries. Publishing updates the knowledge base—email attachments alone are banned. Hits on expired docs must say "retired" or block outright.

  • No effective date—no ingest.
  • Department private drives do not feed the enterprise assistant.
  • Spot-check answers against current official docs; errors feed cleanup.

Confident wrong answers happen because old PDFs still index as authority.

Retire and Publish the Same Day

The XYN digital intelligence system binds policy versions to search—old items leave default recall on revision day. Agents can be fast, but not faster than what is currently in force. Faster than current means spreading expiry.

Take the last policy change—ask the assistant if old clauses still appear. If yes, pull old PDFs before the next AI scenario.

One current document—or none is current. Multiple "current" equals no current.
