Natural Language Processing (NLP)
“Cost us”, from the example sentences earlier, is a noun-pronoun combination but bears some negative sentiment. Even before you can analyze a sentence and phrase for sentiment, however, you need to understand the pieces that form it.

As the data is in text format, separated by semicolons and without column names, we will create the data frame with read_csv() and parameters as “delimiter” and “names”. The first review is definitely a positive one and it signifies that the customer was really happy with the sandwich.
