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.

Sentiment Analysis with GRU

Sentiment analysis is a popular use case for applying natural language processing techniques. The aim of sentiment analysis is to determine whether a given piece of text can be considered as conveying a 'positive' sentiment or a 'negative' sentiment. For example, consider the following text reviewing a book:

"The book had its moments of glory, but seemed to be missing the point quite frequently. An author of such calibre certainly had more in him than what was delivered through this particular work."

To a human reader, it is perfectly clear that the mentioned book review conveys a negative sentiment. So, how would you go about building a machine learning model for the classification of sentiments? As always, for using a supervised learning approach, a text corpus containing several samples is needed. Each piece of text in this corpus should have a label indicating whether the text can be mapped to a positive or a negative sentiment...
