In an age where technology is intertwined with every facet of our lives, the ability of machines to understand and process human language has become increasingly significant. This book, "Natural Language Processing: Teaching Machines to Understand Us," aims to demystify the fascinating field of Natural Language Processing (NLP) and provide a comprehensive guide to its principles, applications, and future directions.NLP bridges the gap between human communication and computer understanding, enabling machines to comprehend, interpret, and generate human language. From the text processing techniques that break down sentences into understandable units to the complex algorithms that enable machine translation and sentiment analysis, NLP is a cornerstone of modern artificial intelligence. The book begins with an introduction to NLP, defining its scope and highlighting the key challenges that researchers and developers face. It then delves into the core components of NLP, including text processing and analysis, information retrieval and extraction, and machine translation. Each chapter provides detailed explanations and practical examples.
