What is text classification and why is it important?

Categorizing text is the first step to understanding language at scale.
Christopher Manning

How It Works:

Text classification assigns labels (like ?spam? or ?positive?) to documents by feeding tokenized text into a trained model that predicts the most likely category.

Key Benefits:

  • Automates sorting of large volumes of text
  • Enables sentiment analysis, topic tagging, and filtering
  • Provides structured insights from unstructured data

Real-World Use Cases:

  • Email spam detection
  • Customer review sentiment scoring
