Sentiment Analysis - Better performance with Naive Bayes model
Just a general question. I'm trying to do SentimentAnalysis with Naive Bayes. For that i build a trainingset with about 2.5k facebookposts and gave them their polartiy manuely. When i run my process now, i get an accurency of about 44.7%. My question now is, how can i get a better performance?
I know, more or less, how Naive Bayes works. But i can't figure out how the Perfomance operator calculate it.
Thanks and kind regards
