I am using the workflow for Lexicon Based Sentiment Analysis and I am trying to understand the formula that was used in this workflow for sentiment prediction. I attached the screenshot of it and would be glad if someone can help me to understand this better. In addition to that, what I want to do is, I want to assign “POSITIVE” sentiment for all sentiment scores higher than “0”, assign “NEGATIVE” sentiment for all scores lower than “0” and all else assign “NEUTRAL”. How can I can do that? Thanks in advance for your help.
