In a pair of previous posts, we first discussed a framework for approaching textual data science tasks, and followed that up with a discussion on a general approach to preprocessing text data. This post will serve as a practical walkthrough of a text data preprocessing task using some common Python tools.
Preprocessing, in the context of the textual data science framework.Our goal is to go from what we will describe as a chunk of text (not to be confused with text chunking), a lengthy, unprocessed single string, and end up with a list (or several lists) of cleaned tokens that would be useful for further text mining and/or natural language processing tasks.
