Edit Build Text Node

The Edit Build Text Node dialog box enables you to define transformations for text columns. The transformed text columns can be used in data mining.

To open the Edit Build Text Node dialog box:

  1. Right-click the Build Text node and select Edit. Alternately, double-click the node. The Edit Build Text Node dialog box opens.

  2. The Edit Build Text Node dialog box has two panes.

    • In the top pane, you can perform the following tasks:

      • Specify the case ID (optional).

      • Open the Stoplist Editor.

      • View attributes: Select All or Text and Transformed from the drop-down list. For each attribute, the following are displayed:
        Type: The data type of the attribute. The type of an attribute that has a text transform applied is DM_NESTED_NUMERICALS.
        Source: The source column for a transformed column.
        Transform: The type of text transform—Token or Theme.
        Output: Indicates if the attribute is passed on to subsequent nodes. By default, all nodes are passed on.

      • Define transformation: To define a transformation, select a text attribute and click add. Define the text transformation in the Add/Edit Text Transform dialog box. Repeat the step for each text attribute.

      • Edit Transformation: Select the transformed attribute and click edit.

      • Delete Transformation: Select the transformed attribute and click delete.

      • Exclude attribute: To exclude attributes, select it and in the Output column of the grid, click pass. The icon changes to ignore. The excluded attribute is not passed on to subsequent operations. You may want to exclude the non-transformed version of a text column.

      • Include attribute: To include an attribute, click the ignore icon again. The icon changes to include, indicating that it is included.

    • In the lower pane, you can view the test transformation after the node is run.

  3. Click OK.
