Summary

In this chapter, we saw that a corpus is the basic building block for NLP applications. We also got an idea about the different types of corpora and their data attributes. We touched upon the practical analysis aspects of a corpus. We used the nltk API to make corpus analysis easy.

In the next chapter, we will address the basic and effective aspects of natural language using linguistic concepts such as parts of speech, lexical items, and tokenization, which will further help us in preprocessing and feature engineering.
