Natural Language Processing

Teach computers to read and understand text. Master text preprocessing, sentiment analysis, and classification using NLTK and Spacy libraries.

Natural Language Processing (NLP) is the foundation of modern AI interaction. This course covers the essential techniques required to process and analyze human language. You will learn to clean raw text (tokenization, stemming, lemmatization), perform part-of-speech tagging, and build models for sentiment analysis and text classification. Using libraries like NLTK and Spacy, you will transform unstructured text into structured data that machines can understand, paving the way for advanced LLM work.
