Exercise

Multiple text columns

In this exercise, you will continue working with the airline Twitter data. A dataset tweets has been imported for you.

In some situations, you might have more than one text column in a dataset and you might want to create a numeric representation for each of the text columns. Here, besides the text column, which contains the body of the tweet, there is a second text column, called negativereason. It contains the reason the customer left a negative review.

Your task is to build BOW representations for both columns and specify the required stop words.
