Python Natural Language Processing

Overview of this book

This book starts off by laying the foundation for Natural Language Processing and why Python is one of the best options to build an NLP-based expert system with advantages such as Community support, availability of frameworks and so on. Later it gives you a better understanding of available free forms of corpus and different types of dataset. After this, you will know how to choose a dataset for natural language processing applications and find the right NLP techniques to process sentences in datasets and understand their structure. You will also learn how to tokenize different parts of sentences and ways to analyze them. During the course of the book, you will explore the semantic as well as syntactic analysis of text. You will understand how to solve various ambiguities in processing human language and will come across various scenarios while performing text analysis. You will learn the very basics of getting the environment ready for natural language processing, move on to the initial setup, and then quickly understand sentences and language parts. You will learn the power of Machine Learning and Deep Learning to extract information from text data. By the end of the book, you will have a clear understanding of natural language processing and will have worked on multiple examples that implement NLP in the real world.

Applications

In this section, I have divided the applications into two sections; one is the NLP application and the other one is the generalized AI application.

NLP applications using the rule-based system

Here, we mention some of the NLP applications that use the RB system:

  • Sentence boundary detection:
    • Sentence boundary detection is easy for general English writing but it will be complicated when you are dealing with research papers or other scientific documents
    • So, handcrafted post-processing rules will help us to identify the sentence boundary accurately
    • This approach has been used by Grammarly Inc. for the grammar correction system
  • Machine translation:
    • When we think of a machine translation system, in our mind, we...
