Text classification is a core NLP task where text documents are assigned to predefined categories. Common applications include spam detection, sentiment analysis, and topic categorization. The process involves converting raw text into numerical features and training a model to predict labels.
A typical workflow includes:
Data gathering – e.g., IMDB reviews or 20 Newsgroups dataset.
Exploration – understanding class distribution and text patterns.
Preprocessing – cleaning, tokenizing, and vectorizing text (e.g., TF-IDF or embeddings).
Model training – using algorithms like SVM, Logistic Regression, or Neural Networks.
Evaluation – measuring accuracy, precision, recall, and F1-score.
Deployment – integrating the model into production systems.
Example: Text Classification with Scikit-learn (SVM + TF-IDF)
