Generative Extractor

UiPath.DocumentUnderstanding.ML.Activities.GenerativeExtractor

Allows you to extract documents using generative models. The Generative Extractor can't extract table fields, as defined in the Taxonomy Manager, but it can extract text and tables from documents.

Tip: For good practices on how to use generative prompts, check the Generative extractor - Good practices page.
Note:

The supported languages for the generative models are the same as the used OCR engine used. For more information, check the OCR Supported languages page.

Properties

Common

  • DisplayName - The display name of the activity.

Misc

  • Private - If selected, the values of variables and arguments are no longer logged at Verbose level.

Server

  • RetryOnFailure - Automatically retries the machine learning model execution, to eliminate transient network errors. If checked, the activity retries the execution.
  • Timeout (milliseconds) - Specifies the amount of time (in milliseconds) to wait for a response from the server before an error is thrown. The default value is 100000 milliseconds (100 seconds).

Using the Manage Prompt Wizard

The Manage Prompt wizard allows you to select a document type and a field, and an optional value to define the prompt. The prompt is used to identify the fields to be extracted, provided as key-value pairs, where the key represents the name of the field and the value a description for it, helping the extractor identify the corresponding value. The same prompt cannot be used for different fields within the same document type.



  1. Select a Document Type and Fields from the list of document types defined. The field selection is done in the Configure Extractors wizard and the prompt is defined in the Manage Prompt wizard.
  2. Add an optional value to define the prompt. This can be a short description of the document type. The maximum number of characters allowed is 1000.
