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.

Applying Convolutions to Text

The relationships between words can be derived by looking at their relative placement with respect to each other. These relationships can be viewed as a time series wherein words that are spoken can be thought of as constituting a time series database. On the other hand, we can view their relative positions and derive relationships out of these. These approaches are used by more complex and modern forms of Artificial Neural Networks (ANNs), known as Convolutional Neural Networks (CNNs) and Recurrent Neural Networks (RNNs). Here, we will deep dive into CNNs and understand how they help us solve problems for the textual domain.

We will begin by understanding what a CNN is and view the various components in the CNN architecture. We will try and form an understanding of convolutions as an operation, followed by exploring the various layers that comprise...
