Sentiment Classification
We finally made it to the final chapter of this project! Now that we know how to understand the sentiment of a tweet we will iterate over our DataFrame and append the results in a new column called "sentiment_predicted"
.
Methods description
-
for index, row in data.iterrows():
: Iterates through the rows of the DataFramedata
; -
blob = TextBlob(row["text"])
: Creates a TextBlob object for each text in the "text" column of the DataFrame; -
sentiment = blob.sentiment.polarity
: Calculates the sentiment polarity of the text using thesentiment
attribute of the TextBlob object. Polarity is a float value within the range [-1.0, 1.0], where negative values indicate negative sentiment, positive values indicate positive sentiment, and zero indicates neutral sentiment; -
data.at[index, "sentiment_predicted"] = sentiment
: Assigns the calculated sentiment polarity to the "sentiment_predicted" column of the corresponding row in the DataFramedata
using theat
method.
