You can connect the output of the sentiment analysis to Test&Score widget together with SVM learner. Test&Score widget can perform different validations (e.g. cross-validation).

enter image description here

If you want to perform testing on different data please use Predictions widget. For more information please check widgets help available with pressing f1 shortcut in Orange.

  • $\begingroup$ The error on the Test&Score widget you get since you are connecting another corpus to SVM widget. In case you are using Test&Score widget SVM does not need an input. It just outputs the Learner. I do not understand the error you have. File widget should also accept CSV file. $\endgroup$
