Selecting entity type handling options from the preview
You can use the preview to select the entity type handling option for each entity type. The options are:
Redaction - This is the default value. Textual replaces the value with the name of the entity type followed by a unique identifier.
For example, the first name John is replaced with NAME_GIVEN_12345. Note that the identifier is only visible in the downloaded file. It does not display on the preview.
Synthesize - Textual replaces the value with a realistic generated value.
For example, the first name John is replaced with the first name Michael. The replacement values are consistent, which means that a given value always has the same replacement. For example, Michael is always the replacement value for John.
Ignore - Textual ignores the value and copies it as is to the output file.
To select the entity type handling option:
In the results panel, click a detected value.
For a PDF file, you can click the value in either the source or the results panel.
On the details panel, click the entity type handling option. Textual applies the same option to all entity values of that type.
Selecting an entity type handling option From the preview, you can only select the entity type handling option. For the Synthesis option, you cannot configure synthesis options for an entity type. You must configure those options from the dataset details page. For more information, go to Configuring entity type synthesis options.
