Natural Language Processing and Computational Linguistics

By: Bhargav Srinivasa-Desikan

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


We've had a look at the incredible power of text analysis, and the kind of things we can do with it – as well as the kind of tools we would be using to take advantage of this. Data has become increasingly easy for us to access, and with the growth of social media, we have continuous access to both new data, as well as standardized annotated datasets.

This book will aim at walking the reader through the tools and knowledge required to conduct textual analysis on their own personal data or own standardized datasets. We will discuss methods to access and clean data to make it ready for pre-processing, as well as how to explore and organize our textual data. Classification and clustering are two other commonly conducted text processing tasks, and we will figure out how to perform this as well, before finishing up with how to use deep learning for text.

In the next chapter, we will introduce how and why Python is the right choice for our purposes, as well as discuss some python tricks and tips to help us with text analysis.
