Definitie

Knowledge Base: is the curated, permissioned store of an organization's documents and data that an AI system retrieves from — through Retrieval-Augmented Generation — to answer questions and act on grounded, current facts rather than guesses.

Directiesamenvatting

Directiesamenvatting

A knowledge base turns scattered documents, policies and records into a single source an AI system can search. Rather than relying on what a model happened to memorize during training, the system retrieves the relevant, permissioned facts at the moment they are needed.

Its value depends entirely on curation and access control: it must contain accurate, current content, and it must expose each piece of information only to the people and agents allowed to see it.

Kernpunten

Kernpunten
  • A knowledge base is what an AI system retrieves grounded facts from.
  • It is accessed through Retrieval-Augmented Generation, not stored inside the model.
  • Quality and permissions matter more than volume.
  • It reduces hallucination by grounding answers in real content.

Architectuur

A usable enterprise knowledge base is defined by a few properties:

  1. 1SourcesDocuments, records and systems ingested and kept current.
  2. 2IndexingContent is chunked and embedded, often in a Vector Database, for retrieval.
  3. 3PermissionsAccess is scoped so retrieval respects who may see what.
  4. 4RetrievalThe relevant passages are fetched and passed to the model at query time.

Without curation and permissions, a knowledge base becomes either stale or a data-leak risk.

Zakelijk voorbeeld

Voorbeeld van een implementatiescenario

A family office keeps procedures, entity records and correspondence in a permissioned knowledge base.

An assistant answers a staff question by retrieving the exact clause from the right document — with no access to entities the employee is not cleared for.

FAQ

Veelgestelde vragen

How is a knowledge base different from training an AI model?
A knowledge base is retrieved from at query time and can be updated instantly, while training bakes information into the model. Retrieval keeps answers current, auditable and permission-aware.
Does a knowledge base stop AI from making things up?
It substantially reduces hallucination by grounding answers in real content, but it does not eliminate it. Human oversight remains necessary for consequential decisions.
