Scorer not working on different training and testing sets for SVM


I am working on sentiment classification of twitter data. I am comparing the accuracy of different models like SVM, Naive bayes and decision tree. But Scorer gives error : "Column "doument class" not found".

I am attaching screenshot of the process here. How to resolve it?


Hi Jasleen,

the workflow attached looks fine. The Scorer is executed successfully. Maybe there is a configuration problem?

Best, Iris
