Rate this book
Develop your NLP skills from scratch, with an open source toolbox of Python packages, Transformers, Hugging Face, vector databases, and your own Large Language Models.

Natural Language Processing in Action, Second Edition has helped thousands of data scientists build machines that understand human language. In this new and revised edition, you’ll discover state-of-the art Natural Language Processing (NLP) models like BERT and HuggingFace transformers, popular open-source frameworks for chatbots, and more. You’ll create NLP tools that can detect fake news, filter spam, deliver exceptional search results and even build truthfulness and reasoning into Large Language Models (LLMs).

In Natural Language Processing in Action, Second Edition you will learn how

• Process, analyze, understand, and generate natural language text
• Build production-quality NLP pipelines with spaCy
• Build neural networks for NLP using Pytorch
• BERT and GPT transformers for English composition, writing code, and even organizing your thoughts
• Create chatbots and other conversational AI agents

In this new and revised edition, you’ll discover state-of-the art NLP models like BERT and HuggingFace transformers, popular open-source frameworks for chatbots, and more. Plus, you’ll discover vital skills and techniques for optimizing LLMs including conversational design, and automating the “trial and error” of LLM interactions for effective and accurate results.

About the technology

From nearly human chatbots to ultra-personalized business reports to AI-generated email, news stories, and novels, natural language processing (NLP) has never been more powerful! Groundbreaking advances in deep learning have made high-quality open source models and powerful NLP tools like spaCy and PyTorch widely available and ready for production applications. This book is your entrance ticket—and backstage pass—into the next generation of natural language processing.

About the book

The second edition of Natural Language Processing in Action by Hobson Lane and Maria Dyshel is a valuable resource for anyone looking to master NLP. Building on the strengths of the first edition, this updated version introduces cutting-edge techniques while maintaining its hands-on, accessible approach. Whether you're a data scientist, AI researcher, or software engineer, this book is an invaluable guide to building practical NLP solutions using Python.
The second edition significantly expands on the original by incorporating recent advancements in NLP, particularly in deep learning and transformer models. Some major enhancements include:
• Expanded Coverage of Transformers – While the first edition introduced basic neural networks, this edition provides an in-depth look at state-of-the-art models like BERT, GPT, and T5, with practical implementations.
• More Hands-On Projects – This edition places even greater emphasis on real-world applications, offering projects such as semantic search engines, text classification, and multilingual translation.
• Integration with Modern Libraries – The first edition focused on foundational NLP with TensorFlow and scikit-learn, whereas the second edition updates the tech stack to include PyTorch and spaCy, ensuring compatibility with the latest industry trends.
• Conversational AI Development – Unlike the previous edition, this book dedicates a full section to chatbot development, covering dialogue management, response generation, and real-world deployment strategies.
In particular the following chapters stood out for me:
• Introduction to NLP Pipelines – This foundational chapter sets the stage by explaining tokenization, stemming, and lemmatization using spaCy, making it easier for newcomers to grasp core concepts.
• Building Neural Networks for NLP – Readers are guided through creating deep learning models with PyTorch, bridging the gap between traditional machine learning and modern AI techniques.
• Transformers and Transfer Learning – This is one of the most valuable chapters, as it walks through implementing cutting-edge transformer models, a topic that was only briefly touched upon in the first edition.
• Conversational AI and Chatbots – A brand-new addition, this chapter provides a roadmap for building interactive AI-driven assistants using open-source tools.
• Deploying NLP Models – Unlike the first edition, which focused mostly on model training, this chapter emphasizes real-world deployment strategies using cloud services and APIs.
What makes the second edition of Natural Language Processing in Action stand out is its ability to balance theory with practice. The authors' expertise shines through in their clear explanations, step-by-step code examples, and engaging writing style. With its inclusion of transformers, conversational AI, and modern NLP frameworks, it is undoubtedly one of the best resources for mastering natural language processing today. Whether you're just starting out or looking to advance your expertise, this book will be a valuable addition to your library.

...Unlike a programming language, where each keyword has an unambiguous interpretation, natural languages are much more fuzzy. Think about the sentence, “The chicken is ready to eat.” This could mean that a live chicken is about to eat its breakfast—or that a cooked chicken is ready in the oven. This fuzziness of natural language leaves the interpretation of each word open to you and introduces interesting challenges in understanding and generating human language...

This book is great for both beginners and experienced ( NLP experts ) learners. It explains topics like preprocessing, TF-IDF, LDA, LSA, CNN, RNN, LSTM, and Attention in a clear and easy way. After each explanation, there are code examples to help us understand concepts better. Author uses real-life examples to show how the concepts work.
Yet to finish the book , will update the review(detailed review) once I finish the book.
