Test a Model on Composed Text

  1. On the Models tab, go to the left-hand pane and select the root Models node.

  2. On the right-hand pane, select the model that you want to test, then right-click and select Test from the shortcut menu. A dialog box appears, titled Model: <modelname>. It contains a Subject box, a Text box, and a box for displaying the test results.

  3. Enter text in either or both of the Subject and Text boxes, then click Classification Test.
