# Structured Ontology Architecture

## Definition

A world model architecture that relies on explicitly defined objects, relationships, and actions to constrain AI reasoning.

## How It Works

The Structured Ontology approach, heavily utilized by [[entity-palantir-d15]], solves the interpretation problem of [[concept-semantic-retrieval]] by drawing a hard, conservative line. In this architecture:

- The business explicitly defines every object (e.g., 'Customer', 'Work Order')
- The exact relationships and actions permitted between them are defined
- The AI is only allowed to reason within this bounded structure
- It cannot hallucinate relationships that do not exist in the schema

This ensures the system handles structured queries flawlessly while leaving all ambiguous interpretation to humans.

## The Boundary Failure: Blindness to Emergence

The boundary failure of this approach is its blindness to emergence. The ontology can only represent what the company has *already* categorized. It is completely blind to:

- Unnamed patterns
- Novel relationships
- Emergent signals that fall outside the predefined schema

By drawing the line so conservatively, the system gains precision but loses the ability to surface unexpected, exploratory insights that a human manager might naturally notice.

See [[claim-ontology-blindspot]] for the formal claim and [[question-ontology-discovery]] for the open architectural question this raises.
