# Semantic Retrieval Architecture

## Definition

A world model architecture that uses vector databases to embed and retrieve company data based on semantic similarity.

## How It Works

Semantic Retrieval is the most popular and fastest-to-deploy architecture for building a [[concept-world-model]]. It involves:

1. Wiring up all company data sources (Slack, Google Docs, Jira)
2. Embedding the text into a vector database
3. Allowing AI agents to retrieve information based on semantic similarity

This approach is highly effective for pure information logistics: synthesizing status, detecting dependencies, and generating reports.

## The Boundary Failure

Its critical boundary failure is that it possesses no structural mechanism to distinguish between *surfacing* information and *interpreting* it. When the system returns a ranked list of relevant documents, that ranking is inherently an editorial claim about what matters — the [[concept-editorial-function]] re-emerging by accident.

Yet, nothing in the vector architecture actually 'knows' what matters to the business. The output arrives with high confidence, leaving the user with no way to tell which results are genuinely critical and which are just semantically adjacent noise.

- At a **small scale**, senior leaders can override this with their own context.
- At a **large scale**, the system's flawed rankings become the company's unintended reality.

See [[claim-semantic-retrieval-flaw]] for the formal claim.
