# Latent Semantic Mapping

Classify text and other token-based content into developer-defined categories.

## Overview

The Latent Semantic Mapping framework classifies texts based on latent semantic information. The C-based functions of this API are designed to be language-independent and are Unicode-based.

For other natural language processing functionality, see <doc://com.apple.documentation/documentation/NaturalLanguage>.
