Overview of this book

Applying deep learning approaches to various NLP tasks can take your computational algorithms to a completely new level in terms of speed and accuracy. Deep Learning for Natural Language Processing starts by highlighting the basic building blocks of the natural language processing domain. The book goes on to introduce the problems that you can solve using state-of-the-art neural network models. After this, delving into the various neural network architectures and their specific areas of application will help you to understand how to select the best model to suit your needs. As you advance through this deep learning book, you’ll study convolutional, recurrent, and recursive neural networks, in addition to covering long short-term memory networks (LSTM). Understanding these networks will help you to implement their models using Keras. In later chapters, you will be able to develop a trigger word detection application using NLP techniques such as attention model and beam search. By the end of this book, you will not only have sound knowledge of natural language processing, but also be able to select the best text preprocessing and neural network models to solve a number of NLP issues.

Activity 11: Build a Text Summarization Model

We will use the attention mechanism model architecture we built for neural machine translation to build a text summarization model. The goal of text summarization is to write a summary of a given large text corpus. You can imagine using text summarizers for the summarization of books or the generation of headlines for news articles.

As an example, use the given input text:

"Celebrating its 25th year, Mercedes-Benz India is set to redefine India's luxury space in the automotive segment by launching the new V-Class. The V-Class is powered by a 2.1-litre BS VI diesel engine that generates 120kW power, 380Nm torque, and can go from 0-100km/h in 10.9 seconds. It features LED headlamps, a multi-functional steering wheel, and 17-inch alloy wheels."

A good text summarization model should be able to produce a meaningful summary, such as:

"Mercedes-Benz India launches the new V-Class"

From an architectural viewpoint, a text summarization...
