Natural Language Processing (NLP) for Data Science

Raw text data is everywhere, but turning unstructured language into actionable insights requires specialized data science skills. This text-based course guides you through the essential concepts and practical workflows of Natural Language Processing (NLP). You will progress from understanding foundational linguistic concepts to implementing sophisticated machine learning and neural network models that can classify text, analyze sentiment, and generate context-aware responses. What you'll learn: - Understand foundational NLP concepts including tokenization, stop-word removal, and text normalization - Apply vectorization techniques like TF-IDF and word embeddings to represent text numerically - Build and train machine learning models for sentiment analysis and text classification - Explore deep learning architectures and modern transformer models for complex language tasks - Implement basic retrieval-augmented generation (RAG) workflows and prompt engineering principles - Evaluate NLP model performance using industry-standard metrics like precision, recall, and F1-score The course starts with essential terminology and text-cleaning basics before moving systematically into machine learning classifiers, deep learning models, and modern transformer-based applications. Through structured written explanations and code examples, you will build a solid theoretical and practical foundation in NLP. This course is designed for aspiring data scientists, developers, and analytical thinkers who are new to natural language processing and want a clear, step-by-step introduction without complex prerequisites.
