The Document Understanding Process template is a fully functional UiPath Studio project template
based on a document processing flowchart. It provides logging, exception handling, retry
mechanisms, and all the methods that should be used in a Document Understanding workflow, out
of the box. The template has an architecture decoupled from other connected automations and
supports both attended and unattended processes with human-in-the-loop validation via Action
Center.🔍The template consists of the following components1:
Load Taxonomy: This component loads the taxonomy file that defines the document types and fields
to be extracted. The taxonomy file can be created using the Taxonomy Manager in Studio or the Data
Manager web application.
Digitization: This component converts the input document into a digital format that can be processed
by the subsequent components. It uses the Digitize Document activity to perform OCR (optical
character recognition) on the document and obtain a Document Object Model (DOM).
Classification: This component determines the document type of the input document using the
Classify Document Scope activity. It can use either a Keyword Based Classifier or a Machine Learning
Classifier, depending on the configuration. The classification result is stored in a ClassificationResult
variable.
Data Extraction: This component extracts the relevant data from the input document using the Data
Extraction Scope activity. It can use different extractors for different document types, such as the
Form Extractor, the Machine Learning Extractor, the Regex Based Extractor, or the Intelligent Form
Extractor. The extraction result is stored in an ExtractionResult variable.
Data Validation: This component allows human validation and correction of the extracted data using
the Present Validation Station activity. It opens the Validation Station window where the user can
review and edit the extracted data, as well as provide feedback for retraining the classifiers and
extractors. The validated data is stored in a DocumentValidationResult variable.
Export: This component exports the validated data to a desired output, such as an Excel file, a
database, or a downstream process. It uses the Export Extraction Results activity to convert the
DocumentValidationResult variable into a DataTable variable, which can then be manipulated or
written using other activities.
