Text Summarization in Python: Build NLP Algorithms from Scratch

With the massive volume of digital text generated daily, extracting key insights quickly is a critical skill. Text summarization is a foundational Natural Language Processing (NLP) technique that automates this process, turning lengthy documents into concise overviews. This course guides you through the core concepts of NLP and text summarization. You will transition from understanding basic linguistic theory to writing your own summarization algorithms from scratch in Python, equipping you with a deep, practical understanding of how machines process and condense human language. What you'll learn: - Understand the core principles of text processing, tokenization, and parsing using NLTK and spaCy - Build frequency-based summarization algorithms to identify key sentences in a document - Implement Luhn's classic heuristic algorithm from scratch to evaluate sentence importance - Apply distance-based summarization using cosine similarity and graph-ranking techniques - Leverage modern pre-trained transformer models for advanced document summarization - Write clean, modern Python code utilizing type hints to structure your text-processing pipelines The course begins with foundational NLP definitions, text preprocessing techniques, and linguistic concepts. From there, you will progress step-by-step through the logic of classic summarization algorithms, culminating in the application of modern pre-trained libraries to handle real-world text summarization tasks. This course is designed for beginners in Python who want to explore Natural Language Processing. No prior experience with NLP or machine learning is required.
