Classifying text involves categorizing written content into predefined tags or labels. It typically utilizes machine learning algorithms like Naive Bayes, Support Vector Machines (SVM), or neural networks. Steps include data collection, preprocessing (e.g., removing stopwords), feature extraction (e.g., TF-IDF), and model training. Proper classification allows for efficient information retrieval, spam detection, and sentiment analysis, among other applications.
