How to Measure Whether AI Answers Stay Grounded After a Knowledge Base Update

11/10/2026

Updating a knowledge base can improve coverage but also introduce duplicate, contradictory, or poorly structured sources. The assistant may cite a document while still using unsupported details in its answer.

What to check

Build before-and-after questions tied to the changed documents, inspect citations and quoted evidence, and measure unsupported claims, retrieval relevance, and abstention behavior. Include questions with conflicting or missing sources.

Recommended next step

Review representative outputs with subject-matter owners, fix source organization or retrieval settings, and monitor grounding metrics after the index refresh. Keep source version and effective date visible for important guidance.
