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).

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. $\endgroup$
