Cleaning up your text
Unstructured text data cannot be directly used in most analyses. Multiple steps need to be taken to go from a long free form string to a set of numeric columns in the right format that can be ingested by a machine learning model. The first step of this process is to standardize the data and eliminate any characters that could cause problems later on in your analytic pipeline.
In this chapter you will be working with a new dataset containing the inaugural speeches of the presidents of the United States loaded as speech_df
, with the speeches stored in the text
column.
