General tab - Properties of Trainable Evaluator window

The Trainable Evaluator trains the correct alternative from the input locators for each subfield. This training information is applied during extraction, and for each subfield, the best alternative is chosen from their respective input locators.

During configuration, it is important to add representative training documents for each subfield.

The table has the following columns:

Name

Add a descriptive name for the subfield.

Input Locator

Select the input locator from the list.

Micro Layout

This setting indicates where this evaluator searches for useful keywords in relation to a candidate. During training, the candidate is the trained value. At runtime, the candidate refers to each of the input locator alternatives as they are evaluated.

The following values are available for this setting:

• Table based.

  Keywords are expected at the top or to the left of the candidate (N and W).

  Use this value when searching for content located in tables. This is the default value for this setting.

• Left top oriented.

  Keywords are expected at the top and left of the candidate (N, NW, and W).

  For example, if the keyword is located in the middle of the page, the candidate should be found in the top left quadrant of the document. Use this value when searching for content located in captions or before colons.

• Symmetric.

  Keywords are expected in all directions around the candidate.

  Use this value when searching for content that is located in running text.

• Line oriented.

  Keywords are expected to the left and to the right of the candidate. (W and E).

  Use this value when searching for content in the same line.

If you change the value for the Micro Layout for a subfield that has already been trained, you must train the project again to ensure that the knowledge base has the correct information.

In addition to the common Transformation Designer buttons, the following buttons are provided:

Add

Adds a new subfield row to the list where you can configure it as needed.

Delete

Deletes the selected subfield from the list.

Up

Moves the selected subfield up one position in the list.

This and the following setting is for organizational purposes only. The order of subfields does not affect the output of this evaluator.

Down

Moves the selected subfield down one position in the list.
