# Automatic IAB Categorization: Organizing Your Curations

## The IAB Categorization Service is an enhanced, automated feature that brings industry-standard organization to all your content. It works in the background to ensure Curations are accurately and reliably tagged and easy to find.

#### What is Automatic IAB Categorization?

This service automatically assigns relevant content labels, known as **IAB Categories**, to your Curations. The IAB (Interactive Advertising Bureau) taxonomy is the industry standard for classifying digital content, ensuring your content is organized professionally and consistently.

**Note:** The IAB Categories cannot be created or edited. They are automatically applied to your curations.

#### Key Benefits

| Benefit | How it Helps You |
| --- | --- |
| **Effortless Organization** | The service runs automatically on the backend. You do not need to lift a finger, your content is categorized instantly as you create it. |
| **Powerful Filtering** | You can use the new, precise IAB tags to quickly filter and sort your Curations (e.g., show only content tagged "Science & Education" or "Travel"). |

| **Industry Standard** | Your content is classified using official IAB standards, ensuring high-quality, professional tagging. |

How It Works (Behind the Scenes)

The service is powered by a **deterministic, rule-based engine**—it does not use complex machine learning or statistical models.

1. **Keyword Analysis:** The system reads the keywords extracted from your content.
2. **Rule Check:** It compares these keywords against defined sets for major content topics (like Health, Politics, or Business).
3. **Refinement:** Based on these rules, the service confirms, adds, or refines the category tags on your content.
4. **Final Tagging:** Your content is labeled with the final, precise IAB Category (limited to the **Tier 2** level for simpler filtering).

#### Getting Started

The Automatic IAB Categorization Service is **immediately active** within Curations.

There are no steps required to activate the service. Simply view your Curations, and you will see the enhanced, rule-based IAB categories applied to your content, ready for filtering.
