First, we will provide a hands-on overview of NLTK by working on some basic NLP tasks, such as text preprocessing and exploratory analysis. The text preprocessing step involves tasks such as tokenization, stemming, and stop word removal. An exploratory analysis of prepared text data can be performed to understand its main characteristics, such as the main topic of the text and word frequency distributions.
Text preprocessing and exploratory analysis
Tokenization
Word tokens are the basic units of text involved in any NLP task. The first step, when processing text, is to split it into tokens. NLTK provides different types of tokenizers for doing this. We will look at how to tokenize Twitter comments from the Twitter samples...
