Teams spend months picking the perfect vector database and embedding model, launch their RAG-powered assistant, and then watch it confidently return wrong answers. The instinct is to blame the model. The real culprit is almost always the knowledge base feeding it.
Retrieval-Augmented Generation is only as good as what it retrieves. Garbage in, confident garbage out.
Why RAG quality is a curation problem
RAG fails in predictable, fixable ways:
- Bad chunking – documents split mid-thought, so retrieved passages lack context.
- Duplicates and contradictions – the system retrieves three conflicting versions of the same policy.
- Stale content – last year’s pricing answered as if it’s current.
- Missing metadata – no way to filter or rank by recency, source, or authority.
- No coverage check – the KB simply doesn’t contain the answer, so the model invents one.
None of these are model problems. They’re data curation problems.
What good RAG curation looks like
- Document ingestion & parsing that preserves structure.
- De-duplication and conflict resolution so there’s one source of truth.
- Smart chunking (roughly 200-500 token, context-aware) instead of blind splits.
- Metadata and lineage tagging for filtering, ranking, and auditability.
- Human-in-the-loop entity validation – people checking that the right things are linked and labeled.
- Freshness re-curation – the KB stays accurate as your data changes.
- Retrieval QA – measuring precision against real query logs, then tuning.
The part tools won’t do for you
Vector DBs and frameworks handle the plumbing. They don’t decide what’s authoritative, resolve contradictions, or validate entities – that’s human judgment. Which is exactly why a managed, human-in-the-loop curation layer is what turns a demo-quality RAG bot into a production-quality one.
How AB7 helps
AB7 provides managed RAG knowledge-base curation – ingestion, parsing, de-duplication, context-aware chunking, metadata/lineage tagging, HITL entity validation, and freshness re-curation – so retrieval stays accurate as your enterprise data changes. It pairs human reviewers with automated pipelines under a security-first process.
