How was the sentiment class and sentiment scores created? Which package was used to create that?

Course Name: Natural Language Processing in Trading, Section No: 4, Unit No: 5, Unit type: Notebook

Hi Gaurav,



As mentioned in the notebook in section 3, unit 4, the sentiment class and score are calculated using the lexical approach, VADER.



Also, note that some of the news data vendors also provide their propritary sentiment analysis data along with the news data.



Hope this helps!
