How it works

Text classification is a fundamental natural language processing task. Given a piece of text, the goal is to assign it to one or more categories, such as spam detection, sentiment analysis, or topic labeling. Machine learning models, including deep learning networks, are trained on labeled text datasets to perform this task.
