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.

Applications of Parts of Speech Tagging

Just like text pre-processing techniques help the machine understand natural language better by encouraging it to focus on only the important details, POS tagging helps the machine actually interpret the context of text and thus make sense of it. While text pre-processing is more of a cleaning phase, parts of speech tagging is actually the part where the machine is beginning to output valuable information about corpora on its own.

Understanding what words correspond to which parts of speech can be beneficial in processing natural language in several ways for a machine:

  • POS tagging is useful in differentiating between homonyms – words that have the same spelling but mean different things. For example, the word "play" can mean the verb to play, as in engage in an activity, and also the noun, as in a dramatic work to be performed on stage. A POS tagger can help the machine understand what context the word "play" is being...
