Document Understanding Activities
Last updated Feb 14, 2025
Manual validation for digitize documents
The example below explains how to manually extract data from an image and present the output in a separate file. It presents activities such as Digitize Document or Present Validation Station. You can find these activities in the UiPath.IntelligentOCR.Activities package.
Note: This workflow is using an older version of the UiPath.IntelligentOCR.Activities package.
Steps:
- Open Studio and create a new Process named
by default Main.
Note: Make sure to add all the needed files (
.jsonfiles and all the images) inside the project folder. - Add a Sequence container in the
Workflow Designer and create the variables shown in
the following table:
Table 1. Variables to be created Variable Type
Default Value
TextString
DOMUiPath.DocumentProcessing.Contracts.Dom.Document
DataUiPath.DocumentProcessing.Contracts.Taxonomy.DocumentTaxonomy
DocumentTaxonomyUiPath.DocumentProcessing.Contracts.Taxonomy.DocumentTaxonomy
TaxonomyJSONString
HumanValidatedUiPath.DocumentProcessing.Contracts.Results.ExtractionResult
- Add a Read Text File activity inside the
sequence.
- In the
Properties panel, add the name of the file,
in this case
"taxonomy.json", in the FileName field. - Add the
variable
TaxonomyJSONin the Content field.
- In the
Properties panel, add the name of the file,
in this case
- Add an Assign activity after the Read
Text File activity.
- Add the
variable
Datain the To field and the expressionDocumentTaxonomy.Deserialize(TaxonomyJSON)in the Value field. This activity builds the taxonomy for extraction.
- Add the
variable
- Add a Digitize Document activity after the
Assign activity.
- In the
Properties panel, add the value
1in the DegreeOfParallelism field. - Add the
expression
"Input\Invoice01.tif"in the DocumentPath field. - Add the
variable
DOMin the DocumentObjectModel field. - Add the
variable
Textin the DocumentText field.
- In the
Properties panel, add the value
- Add a Google OCR engine inside the
Digitize Document activity.
- In the
Properties panel, add the variable
Imagein the Image field. - Select the check box for the ExtractWords option. This option extracts the on-screen position of all detected words.
- Add the
expression
"eng"in the Language field. - Select
the option
Legacyfrom the Profile drop-down list. - Add the
value
2in the Scale field.
- In the
Properties panel, add the variable
- Add a Present Validation Station activity
after the Digitize Document activity.
- In the
Properties panel, add the variable
DOMin the DocumentObjectModel field. - Add the
expression
"Input\Invoice01.tif"in the DocumentPath field. - Add the
variable
Textin the DocumentText field. - Add the
variable
Datain the Taxonomy field. - Add the
variable
HumanValidatedin the ValidatedExtractionResults field.
- In the
Properties panel, add the variable
- Add a For Each activity under the
Present Validation Station activity.
- In the
Properties panel, select the option
UiPath.DocumentProcessing.Contracts.Results.ResultsDataPointfrom the TypeArgument drop-down list. - Add the
expression
HumanValidated.ResultsDocument.Fieldsin the Values field.
- In the
Properties panel, select the option
- Add a Log Message activity inside the
Body of the For Each activity.
- Select
the option
Infofrom the Level drop-down list. - Add the
expression
item.FieldNamein the Message field.
- Select
the option
- Add a Log Message activity below the first
Log Message activity.
- Select
the option
Infofrom the Level dropdown list. - Add the
expression
item.Values(0).Value.ToStringin the Message field.
- Select
the option
- Add a Write Line activity under the Log
Message activities.
- Add the
value
""in the Text field.
- Add the
value
- Run the process. The robot uses the IntelligentOCR activities to manually process the data and to present the results.
