Confusion Matrix for Analyze Sentiment Operator
Hello. I have not used RapidMiner for a while, so please forgive the noob question. I am trying to recreate a RapidMiner model that I had read in an academic journal. The model uses the Aylien "Analyze Sentiment" operator to do sentiment analysis of a movie review dataset. I need to generate a confusion matrix for this model. I tried to insert a performance operator, but it kept giving me an error saying it was expecting a label. Each item in the dataset comes with a "polarity" label, so I don't know what I am not doing correctly. Any suggestions?
