Taxonomy

A system for organizing and categorizing information, often in a hierarchical structure.

In plain terms

A taxonomy is a way to organize and classify things. Think of it like a library's system for sorting books by genre, author, and subject. This helps people find what they are looking for more easily.

In AI, taxonomies are used to categorize data, identify different types of content, or group similar concepts. For example, a system might use a taxonomy to classify images into categories like 'animals', 'vehicles', and 'landscapes'. This helps the AI understand and process information more effectively.

The expert version

A taxonomy is a structured classification system, typically hierarchical, used to organize concepts, data, or entities. It defines relationships between categories, such as parent-child or sibling relationships, enabling systematic organization and retrieval. Taxonomies are fundamental in areas like knowledge representation, data labeling, and content moderation, providing a framework for understanding and managing complex information spaces.

In the context of AI safety, taxonomies are crucial for defining and detecting undesirable content. A well-defined taxonomy allows for granular classification of harmful or inappropriate material, aiding in the development of robust detection models and policy enforcement.

Why it matters now

Recent discussions around managing AI risks and improving developer tools highlight the need for clear categorization. Microsoft's work on open-weight model risk and GitHub Copilot's features for defining governance rules both rely on organizing information effectively. OpenAI's approach to content detection also involves classifying different types of undesirable outputs.

The term 'taxonomy' originates from biology, specifically from the work of Carl Linnaeus in the 18th century for classifying living organisms. The concept has since been adopted and adapted across many scientific and information management fields. Source ↗

Ask an AI chatbot to list different types of dogs and their breeds. Observe how it organizes the information, likely using a hierarchical structure similar to a taxonomy. You can then ask it to explain the relationship between different breeds or categories.
