Evaluation Settings tab - Properties of Advanced Evaluator window
Use the
Advanced Evaluator to return the best extraction results from multiple input locators for a set of
subfields commonly found on invoice and purchase order documents. For each subfield, define evaluation steps and confidence
thresholds for the input locators to find the correct result in a voting process.
This evaluator provides comparisons for up to three input
locators for typical invoice header data, such as invoice number, order date, different amounts, or other custom subfields.
Each subfield that was added to the Evaluator Subfields list on the Subfields tab has its own set of settings. These settings are as follows:
- Formatter
-
Select a formatter in the list so that the alternatives from the selected input locator can be compared based on their formats. (Default: none)
You can edit the selected formatter by clicking on its properties
button. Alternatively, if the desired formatter is not available, you can click on the
Formatting button. The
Formatting tab on the
Project Settings window is displayed so you can add a new formatter.
- Input Locator 1 / Input Locator 2 / Input Locator 3
-
Select a locator for one or more of the input locators from the lists. Once selected, additional settings become available. (Default: none)
The area below the input locator list contains the evaluation steps for each of the selected locators. You can manage the evaluation steps using the following settings:
- Use this evaluation step for processing
-
Each evaluation step has a check box with a corresponding number above it. When selected, the input locators are evaluated as configured. (Default: Selected)
- Use alternatives for input locator / Ignore alternatives for input locator
-
If an input locator is selected, additional settings are available in the column directly below. Click the Ignore
button to use the above locator in this evaluation step. When clicked, the button changes to the
Use
button.
(Default:
Ignore)
- Training
-
If a trainable locator is selected as the input locator, additional buttons are available. Select the G button
to use alternatives returned by the generic training algorithm. Select the S button
for alternatives returned by the specific training algorithm, and select the § button
to use rules based alternatives for this locator. All three settings are selected by default.
- Input Locator Minimum Confidence
-
This setting is only available if the input locator is set to Use
. Alternatives need to be greater or equal to the specified confidence in order to be returned for evaluation.
(Default: 60)
- Output confidence set to
-
If selected, this setting changes the output confidence of the best alternative to the specified value to the right. This effectively increases the overall confidence of an alternative because it is returned by locators. (Default: Cleared)
- Output minimum confidence
-
This setting is only available if the Output confidence set to setting is selected. Set the confidence for the found alternative. (Default: 60)
Use the following buttons to manage your evaluation steps:
Add
-
Creates a new row so you can have additional evaluation settings.
Delete
-
Removes the selected row of evaluation settings.
-
Move Up
-
Moves the selected evaluation setting up one position in the list so it is evaluated earlier in the process.
Move Down
-
Moves the selected evaluation setting down one position in the list so it is evaluated later in the process.
