I wanted to perform Twitter sentiment analysis on Twitter tweets. When I googled it, I found a stanfordNLPstanfordNLP code of sentiment class. I used it for finding Twitter sentiment later I came to know twitter GateTwitterGate model is made for Twitter tweets only.
Then I replaced the stanfordNLPstanfordNLP model with TwitterGateTwitterGate model. I did not find any difference in the sentiment results. Both models give the same result. But
However, when I tested the same tweets with monkeylearn apiMonkeylearn API and datumbox apiDatumbox API sentiment results., I got confused with results. In NLP and twitterGate most tweets sentiment is given as negative, where the same Tweetstweets sentiment is given as neutral in MonkeylearnMonkeylearn & Datumbox apisDatumbox APIs code.
How can I know model which model is giving the correct sentiment?
