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.

POS Tagging

Before we dive straight into the algorithm, let's understand what parts of speech are. Parts of speech are something most of us are taught in our early years of learning the English language. They are categories assigned to words based on their syntactic or grammatical functions. These functions are the functional relationships that exist between different words.

Parts of Speech

The English language has nine main parts of speech:

  • Nouns: Things or people
  • Examples: table, dog, piano, London, towel
  • Pronouns: Words that replace nouns
  • Examples: I, you, he, she, it
  • Verbs: Action words
  • Examples: to be, to have, to study, to learn, to play
  • Adjectives: Words that describe nouns
  • Examples: intelligent, small, silly, intriguing, blue
  • Determiners: Words that limit nouns
  • Examples: a few, many, some, three
