Book Description
Natural Language Processing (NLP) is a collection of techniques to analyze,interpret,and create human-understandable text and speech. Advances in machine learning have pushed NLP to new levels of accuracy and uncanny realism. Natural Language Processing for Hackers lays out everything you need to crawl,clean,build,fine-tune,and deploy natural language models from scratch—all with easy-to-read Python code.
Thanks to NLP,computers are capable of highly accurate text and speech-based interaction with humans. NLP capitalizes on powerful machine learning techniques that can detect patterns and extract meaning from human-generated text. As well as improving raw data processing,NLP technology is behind cutting edge UI developments such as chatbots and voice assistants that can process written and spoken commands and generate realistic and helpful responses.
Natural Language Processing for Hackers covers NLP end-to-end,giving you the skills and techniques that allow your computers to speak human. Unlike many research-oriented books that use the kind of clean datasets you would never find in the real world,this practical guide takes on NLP as you’ll actually use it. You’ll learn the key concepts of NLP by coding your own tools and projects,from a text analysis service right up to a full-featured chatbot. Everything is written in concise,easy-to-read Python code to ensure you’ll grok the most important aspects of Natural Language Processing. When you’re done,you will be able to apply the complete range of NLP techniques to build practical applications—even with messy real-world data.
