Natural Language Processing and Computational Linguistics

Overview of this book

Modern text analysis is now very accessible using Python and open source tools, so discover how you can now perform modern text analysis in this era of textual data. This book shows you how to use natural language processing, and computational linguistics algorithms, to make inferences and gain insights about data you have. These algorithms are based on statistical machine learning and artificial intelligence techniques. The tools to work with these algorithms are available to you right now - with Python, and tools like Gensim and spaCy. You'll start by learning about data cleaning, and then how to perform computational linguistics from first concepts. You're then ready to explore the more sophisticated areas of statistical NLP and deep learning using Python, with realistic language and text samples. You'll learn to tag, parse, and model text using the best tools. You'll gain hands-on knowledge of the best frameworks to use, and you'll know when to choose a tool like Gensim for topic models, and when to work with Keras for deep learning. This book balances theory and practical hands-on examples, so you can learn about and conduct your own natural language processing projects and computational linguistics. You'll discover the rich ecosystem of Python tools you have available to conduct NLP - and enter the interesting world of modern text analysis.

Summary


With the knowledge of the functions and strategies we have discussed, our text analysis can be aided; it is often when we are doing large scale text analysis that a small error can lead to completely nonsense results (remember garbage in, garbage out from Chapter 1, What is Text Analysis?).

We finish this mini-chapter with a few useful links on basic text manipulation:

  1. Printing and Manipulating Text [9]: Basic manipulation and printing of text, recommended if interested in how to display text in different ways.
  2. Manipulating Strings [10]: Basic String functions as well as exercises, useful for the further practice of string manipulation.
  3. Manipulating Strings in Python [11]: Similar to the two-preceding links includes a section on escape sequences as well.
  4. Text Processing in Python (book) [12]: Unlike the other links, this is a whole book. It covers the very fundamentals of text and string manipulation in Python and includes useful material on some uncovered topics such as regular expressions...
