Overview of this book

Natural Language Processing (NLP) is the subfield in computational linguistics that enables computers to understand, process, and analyze text. This book caters to the unmet demand for hands-on training of NLP concepts and provides exposure to real-world applications along with a solid theoretical grounding. This book starts by introducing you to the field of NLP and its applications, along with the modern Python libraries that you'll use to build your NLP-powered apps. With the help of practical examples, you’ll learn how to build reasonably sophisticated NLP applications, and cover various methodologies and challenges in deploying NLP applications in the real world. You'll cover key NLP tasks such as text classification, semantic embedding, sentiment analysis, machine translation, and developing a chatbot using machine learning and deep learning techniques. The book will also help you discover how machine learning techniques play a vital role in making your linguistic apps smart. Every chapter is accompanied by examples of real-world applications to help you build impressive NLP applications of your own. By the end of this NLP book, you’ll be able to work with language data, use machine learning to identify patterns in text, and get acquainted with the advancements in NLP.

Summary

In this chapter, we understood a specialized form of neural network, that is, CNNs, which help us capture spatial relationships and patterns in data. We looked at the various components involved in a CNN for encompassing convolutions, pooling, fully connected layers, and their functionality. We understood the way spatial relationships can exist in text and how can we extract them using CNNs. Finally, we applied all our understanding to solve a fairly complex problem regarding detecting sarcasm from text data using CNNs and pre-trained word embeddings from the Word2Vec algorithm.

In the next chapter, we will expand on the knowledge we gained in this chapter and look at another specialized form of neural network known as RNNs. We will look at the improvements we can make to the RNN architecture, which are suited for natural language data as they tend to capture temporal relationships in data.
