Overview of this book

Natural Language Understanding facilitates the organization and structuring of language allowing computer systems to effectively process textual information for various practical applications. Natural Language Understanding with Python will help you explore practical techniques for harnessing NLU to create diverse applications. with step-by-step explanations of essential concepts and practical examples, you’ll begin by learning about NLU and its applications. You’ll then explore a wide range of current NLU techniques and their most appropriate use-case. In the process, you’ll be introduced to the most useful Python NLU libraries. Not only will you learn the basics of NLU, you’ll also discover practical issues such as acquiring data, evaluating systems, and deploying NLU applications along with their solutions. The book is a comprehensive guide that’ll help you explore techniques and resources that can be used for different applications in the future. By the end of this book, you’ll be well-versed with the concepts of natural language understanding, deep learning, and large language models (LLMs) for building various AI-based applications.

Summary

In this chapter, we surveyed the various techniques that can be used in NLU applications and learned several important skills.

We learned about what rule-based approaches are and the major rule-based techniques, including topics such as POS tagging and parsing. We then learned about the important traditional machine learning techniques, especially the ways that text documents can be represented numerically. Next, we focused on the benefits and drawbacks of the more modern deep learning techniques and the advantages of pre-trained models.

In the next chapter, we will review the basics of getting started with NLU – installing Python, using Jupyter Labs and GitHub, using NLU libraries such as NLTK and spaCy, and how to choose between libraries.
