Definition
Text classification is a supervised learning task where algorithms assign predefined categories to unstructured text data. Common techniques include Naive Bayes, Support Vector Machines, and Deep Learning models like LSTMs or Transformers. Applications range from sentiment analysis and spam detection to topic labeling and intent recognition, forming a foundational component of Natural Language Processing systems.
