# Taxonomies

> Create hierarchical classification systems for organizing knowledge

## Overview

Taxonomies provide structured, hierarchical vocabularies for classifying and categorizing entities in the knowledge graph. They help ensure consistent tagging and enable structured browsing of your organization's knowledge.

Navigate to **Admin > Graph > Taxonomies**.

## Viewing Taxonomies

The taxonomies page displays a hierarchical tree table showing:

* Taxonomy name
* Parent-child relationships
* Full path from root to leaf
* Associated synonyms
* Status information

You can filter taxonomies by **type** to focus on a specific classification system.

## Creating Taxonomies

Click **Add New Taxonomy** to create a new entry:

| Field        | Description                                                                  |
| ------------ | ---------------------------------------------------------------------------- |
| **Name**     | The taxonomy term (e.g., "Healthcare", "Federal Contracting")                |
| **Type**     | The classification system this belongs to (e.g., "Industry", "Service Line") |
| **Parent**   | Optional parent taxonomy for hierarchical nesting                            |
| **Synonyms** | Alternative terms that should be treated as equivalent                       |

### Hierarchical Structure

Taxonomies support unlimited nesting depth. For example:

```
Industry
├── Healthcare
│   ├── Pharmaceuticals
│   └── Medical Devices
├── Technology
│   ├── Software
│   └── Hardware
└── Government
    ├── Federal
    └── State & Local
```

## Type-Specific Views

Click on a taxonomy type in the sidebar to see a filtered view showing only taxonomies of that type. This provides a focused view for managing a single classification system.

## Synonyms

Each taxonomy entry can have multiple synonyms — alternative terms that the AI treats as equivalent during classification. For example:

* **Healthcare** → "Health Care", "HC", "Medical"
* **Federal** → "Fed", "US Government", "USG"

Synonyms improve classification accuracy by helping the AI recognize variations in terminology.

## Managing Taxonomies

### Editing

Click any taxonomy entry to edit its name, parent, type, or synonyms.

### Deleting

Remove taxonomy entries that are no longer needed. Deleting a parent entry does not automatically delete its children — you'll need to reassign or remove them separately.

<Tip>
  Build your taxonomy before ingesting documents. The AI uses taxonomies during classification, so having a well-defined vocabulary from the start produces better results.

## Related: Inference Rules

Taxonomies are also used in [Enrichment Rules](/admin-guide/enrichment-rules) via the `@TaxonomyName` syntax. When you reference a taxonomy in an enrichment prompt (e.g., `@Domain`), the system expands it to the full list of values, helping the LLM classify and tag nodes consistently.
