Once the text data polarity is found, it can be assigned as a separate column in the dataframe. Subsequently, the sentence polarity can then be used for further analysis.
Polarity and Subjectivity are ...

Several aggregation rules come to mind:
simply calculate the sum of all binary features (and multiply by -5 if you ...

Manually assigning a value to a feature level can be done. However, it is often better to allow the machine learning algorithm to learn the importance of different features during the training process.
The general machine learning process starts with labeled data. If the labels are numeric, it is a regression problem. In the specific case of fake tweets, a ...
