[@himjanand2034]

thanks ! great tutorial

[@naderbouchnag3]

thanks for the video ! i want to know how to calculate the compound score ? it's clear that it's not the mean of the neg , post and neut score

[@aslearning4818]

he compound score is the sum of positive, negative & neutral scores which is then normalized between -1(most extreme negative) and +1 (most extreme positive).

Good one. But why you say, its a machine learning library. Where as its basicllay a rule based library isn't it ?

[@aslearning4818]

It is a rule based library. Rule based libraries are a part of artificial intelligence whose heart is machine learning...🙂

How to handle these types of sentences "No problems with it and does job well. Using it for Apple TV and works great. I would buy again no problem" as in vader it is consider as negative sentence

[@aslearning4818]

Either you can customise VADER as your client data or try other library. Their is no perfect model,everyone will have it's pros and cons.

[@GoneFishingPuntaCana]

I don't know how you got negative, score for your example is pos: 41.6 / neu: 58.4 / neg: 0 / comp: 77.16

How would you use Vader to undergo a sentiment analysis for a dataset in a cvs file ? Like a series of tweets
