Release Date: 9 May 2022
We have been working hard to give a new face to some of our wizards, hence, the Validation Station, Classification Station, and Taxonomy Manager now all have a brand-new interface that is very user friendly and presents multiple new functionalities.
Some of the features worth mentioning from Validation Station are the confidence scores shown for each extracted field. They can be sorted by OCR or Extractor and show you exactly the confidence score for each extracted field. The confidence score should be used only for guidance purposes. You can always improve that score by manually validating the data.
The Validation Station wizard also has a restyled header in the PDF viewer from where you can choose to swipe the document view from left to right, to hide the extracted tokens for a clean view of the document, or to visualize the keyboard shortcuts. Don't hesitate anymore and go, try it out!
The Classification Station wizard presents itself with the same restyled header in the PDF viewer as its peer, the Validation Station. Here, you can also choose to display the document on the left or right side of the screen, or you can check the available keyboard shortcuts. The rotate option is also available in the new header, making document manipulation easier than ever!
The Taxonomy Manager wizard has, among other improvements, a new, particularly useful one, a Delete option available in the header of the document type that also enables a bulk delete.
The UiPath.IntelligentOCR.Activities package has been upgraded to .NET5 portable, allowing you to run them on Linux robots.
The UiPath Studio MSI size has been optimized and the UiPath.IntelligentOCR.Activities package is not anymore a core package of the UiPath Studio MSI, but an optional one. All functionalities remain the same. The only change is that you need to manually install the package in UiPath Studio.
The Digitize Document activity and the Intelligent Keyword Classifier activity have been updated and the ForceApplyOCR option has been replaced by the ApplyOcrOnPdf option. The Apply OCR on PDF has three options available in the dropdown list: True, False, and Auto. If set to True, the OCR is applied to all PDF pages of the document, if set to False, only digitally typed text is extracted. The default value is Auto, determining if the document requires to apply the OCR algorithm depending on the input document.
In Classification Station wizard, the value of the Not Classified groups is now set as N/A.
The Intelligent Form Extractor activity deprecation is planned for October 2022. We recommend using the Form Extractor activity.
The Form Extractor activity can now process documents with detected signatures on them.
- Fixed a bug occurring on the Validation Station wizard. Certain Asian fonts were not correctly displayed in the PDF Viewer of the Validation Station.
- Fixed a bug occurring while using the Digitize Document activity with UiPath Studio v19.10 and v20.10. An error was thrown when trying to process
.tifffiles. Now, everything works as expected. - Fixed a bug occurring on the Validation Station while using the TAB shortcut key. Instead of saving the changes, the TAB key was reverting the field to the previous value. Now, everything works as expected.
- Fixed a bug occurring on the Form Extractor activity. The wrong error message was displayed when a template was imported.
- In case you use an Intel Xe GPU and Taxonomy Manager, Validation Station, or Classification Station are not displayed properly, we recommend updating the graphics driver to the latest version. For more information, please visit this page.
Release Date: 19 October 2021
The Taxonomy Manager received a complete overhaul, with an improved UI and user experience. You can now add document types without group or category, configure colors and hotkeys for fields, and more. Consult the documentation for a complete description.
The UiPath.IntelligentOCR.Activities package has been upgraded to .NET5. While both .NET versions continue to be supported, the .NET5 projects can only work on 64-bit architectures.
The digitization process has been improved for the entire framework throughout Document Understanding and Data Manager.
Improvements have been made to optimize the OCR results on scanned documents. Best results are obtained by keeping the skew angle between +/- 20 degrees.
Image processing dimensions have been improved for better results. For an image to be successfully digitized/processed, its width and height dimensions should be between 50 and 10000 pixels. Any image below or above this range is to be rejected, with an exception message. An image validated with the previously mentioned dimensions and with a total size bigger than 14MP is to be scaled down to 14MP, while maintaining the aspect ratio (width/height ratio).
DocumentRejectedByUserException is thrown and the process is stopped.
Improved the load time of Validation Station for document types with large taxonomies.
For derived parts in Validation Station, numbers with more than two decimals are not rounded up anymore.
Due to improvements to image processing algorithms, changes might appear in the digitization of certain documents.
A new checkbox has been added to the Template Manager wizard, allowing you to choose if the added synonyms are case sensitive or not.
A design update has been made to the Template Manager wizard accessible from the Intelligent Form Extractor and Form Extractor activities.
If you experience timeouts due to long processing time, you can now use the newly added Timeout parameter for Form Extractor and Intelligent Form Extractor to increase the service call timeout.
If a field is checked in both Signature and Handwritten boxes in the Template Manager wizard of the Intelligent Form Extractor activity, then a popup message appears informing you that a field can be added only in one box, not both.
The wizard available for the Intelligent Keyword Classifier activity received an update, meaning that clicking the OK button of the vector(s) exported message now returns the user to the wizard instead of closing the wizard.
The Create Document Validation Action and Present Validation Station activities, received a new parameter, ShowOnlyRelevantPageRange. This allows you to configure the activity so that it only shows the page range captured in the classification part of the extraction result.
Performance and memory improvements in the Digitize Document activity.
CefSharp reference was updated to version 92.0.260.
- Fixed a bug that occurred when OCR was run on different OS region formats. Now, the OCR runs as expected and all results are generated correctly, no matter of the OS region format.
- Fixed a bug in the Export Extraction Results activity that was deleting the extracted table when a field was marked as handwritten. Now, the entire extraction result is exported as expected.
- Fixed an issue related to Validation Station that was causing unexpected number formatting when reading the derived parts value.
- Fixed a bug in the Wait For Validation Action activity that was returning an error when the Automatic Extraction Result parameter was set as empty. Now, the activity runs as expected, without any errors.
- Fixed an issue that threw a runtime error when no extraction results were served to the Present Validation Station activity.
- Fixed an issue in Digitize Document activity, that caused the activity to crash when the ForceApplyOCR parameter was set to False.
- Fixed an issue in the Template Manager wizard that caused data not to be extracted when using the table selection with Form Extractor.
- Fixed an issue that caused derived parts to not be extracted for a date field when processing a specific document.
- Fixed an issue in the Template Manager wizard that caused anchors not to be highlighted after marking a table.
- Fixed an issue that was causing the Data Extraction Scope activity to throw an error when stating that the fields from the extractors configuration could not be found in the taxonomy, although the extractors were removed from the scope.
- Fixed an issue that caused the Template Manager wizard to throw an error when trying to save a template with certain words added as page evidence.
- Fixed an issue which prevented the display of an empty Validation Station with full manual processing for data entry when the AutomaticExtractionResults parameter was null.
- Fixed a bug that was occurring when special characters were included in the file or bucket name for any of the following activities: Create Document Classification Action, Wait for Document Classification Action, Create Document Validation Action, Wait for Document Validation Action. Now, all special characters from the file/bucket names are encoded as expected.
- Fixed an issue that was causing signature and handwritten fields to not be extracted due to the background contrast. Now all fields are correctly extracted, no matter of the background color.
- Fixed a bug that was causing the OCR engine to return an error on certain air-gapped systems.
- Fixed a bug that was merging the extracted content when using the Digitize Document activity with the UiPath Document OCR engine. Now, each item is extracted separately.
- If you want to use any OCR activity from this package in Studio v2019.10, please install the UiPath.CoreIPC package, version 2.0.1 or higher.
- If you install the UiPath.IntelligentOCR.Activities package, v5.0.0 on a machine using Windows N/KN as an operating system, then the Media Features package is also required. Here you can find installation instructions for the Media Features package.
Release Date: 29 March 2021
Extended the Form Extractor and Intelligent Form Extractor capabilities by adding field-level anchor-based extraction rules. Besides page-level anchors, field-level anchors can now be defined in Template Editor - a new option of defining the bounds of a custom area from which data is to be extracted. As opposed to page-level configurations, which define data positions with respect to the entire page content, anchor-based configurations now allow for targeting data extraction based on field-level configurations, thus allowing for more flexibility.
Performance improvements on Validation Station.
Updated Validation Station and Classification Station design system for a better user experience.
The Validation Station, Classification Station, and Template Manager now have a three-state button, in the Document View side, that allow users to choose between different document interaction modes: Tokens (word selections), Custom area (area selection), and Choice on selection (users can choose between Tokens and Custom Area at each selection).
The user interfaces, Validation Station, Classification Station, and Template Manager, have been improved with a new selection mode in text view, now allowing users to perform selections from the text version of a document in the same way they interact with the original version. A new hotkey, d+s, was also added, to assist in switching between the original document view and the text view modes.
The Validation Station now displays a "crop" from the original document, when you assign a value to a data field, under the reported text value selected. This helps with locating and verifying a specific field value against the value area in the document.
Changed confidence calculation for Intelligent Keyword Classifier to be scalable with the length of the word vectors.
Added the IncludeOCRConfidence checkbox to the properties panel of the Export Extraction Results activity. If selected, the exported information will contain OCR Confidence for each value as well.
Improved letter and word processing algorithms to avoid reporting duplicate characters or words in certain situations.
Classify Document Scope and Train Classifiers Scope now support classifier capabilities.
Classify Document Scope has been optimized to perform sequential calls to the classifiers in its scope, with only the page ranges that are not already classified by a previous extractor.
- Fixed an issue that threw a runtime error in specific cases when a Form Extractor activity and an Intelligent Form Extractor activity were in the same Data Extraction Scope.
- Fixed an issue that prevented classifier errors to be thrown in specific cases, but classification failed silently.
- Fixed an issue that caused derived parts not to be extracted for a number field when processing a specific document.
- Fixed an issue in Digitize Document, that caused the activity to process document pages even after an exception was reported, thus increasing the overall execution time for cases of failure.
- Fixed a bug that did not allow for the correct configuration of Regex expressions in Regex Based Extractor, in C# projects, and other very specific situations.
- Fixed a performance issue that appeared in Validation Station and Template Editor, when a document type contained more than 200 fields.
- Fixed a bug in which, in certain situations, numbers were merged into a single reported numeric value.
- Fixed an issue through which, in certain situations, the Wait for Document Validation Action and Resume activity would throw an exception when communicating with storage buckets.

New activities
Five new activities have been included in the package:
- Present Classification Station - designed for classifying and separating files based on the document type.
- Create Document Classification Action & Wait for Document Classification and Resume - designed for integration with Orchestrator.
- Intelligent Keyword Classifier & Intelligent Keyword Classifier Trainer - designed for classifying, splitting, and training document packages into individual document types.
Validation Station
To easily identify the information in the Validation Station, color codes were added to field cards and tokens or custom areas. Each field card has by default a color code, while tokens or custom areas get the same color code as the field card they are assigned to.
New shortcuts have been added to Validation Station allowing the user to move a selected line from a table up, down, left, or right. Also, when selections are made in Validation Station, these can be assigned to a specific field using field-level shortcuts. Each field card has a key associated with it. When no selections are made, you can use field-level shortcuts to jump from one field card to another.
For Validation Station table fields, a row-level checkmark was added. You can now check all the fields from a row by selecting the checkmark or it will be automatically checked when you visit all the fields.
Tokens in Validation Station have been updated. Thus, the highlighted tokens have a red bottom border and the selected tokens have a dashed border.
Field values with no reference are now supported in Validation Station. Users can assign values to fields that do not have a reference in the document. To do so, while the user creates a field in Taxonomy Manager, the Requires Reference checkbox needs to be unchecked.
Classification Station
New shortcuts were created for Classification Station allowing the user to navigate through document types; add, change, remove or highlight reference; move all pages up or down; split after selected page; discard changes; save; report as exception.
Besides using the document type menu, a reference can now be removed at page level as well by hovering over a page and clicking the blue icon in the bottom right corner. The icon also allows the user to highlight the reference.
PDF Viewer in Classification Station and Validation Station
The Rotate button was added to the PDF Viewer. By clicking the button, the current document page will rotate clockwise.
Selection mode is enabled by default in PDF Viewer.
Other activities
The Intelligent Form Extractor and Form Extractor activities can now incorporate imported templates that have the same name but different content as the already available ones. Each template is analyzed, and a warning message is displayed for each case.
The ActionPriority property from the Create Document Validation Action activity now supports expressions and variables.
The terms BucketFolderPath and DirectoryFolderPath were changed to BucketDirectoryPath and DownloadDirectoryPath for the Create Document Validation Action activity, respectively for the Wait for Document Validation Action and Resume activity. The reason behind this is to clearly separate from the Orchestrator concept of “Folder”.
Release Date: 24 August 2020
407ProxyAuthenticationRequired error message for Kerberos or NTLM authentication requests. This applies to Form Extractor, Intelligent Form Extractor, and
Intelligent Keyword Classifier.
- Fixed an issue that was causing the Intelligent Form Extractor to not properly display a timeout error.
- Missing translations were added for certain Validation Station strings.
- Fixed an issue that was causing the Data Extraction Scope to throw an error when unselecting a table field.
Release Date: 24 June 2020
Release Date: 4 May 2020
New Features and Improvements
This release brings many new exciting activities such as Create Document Validation Action, and Wait for Document Validation Action and Resume that can be used to create, suspend, and resume orchestration workflows in the UiPath Action Center.
Two new extractors are here to be of your help. You can find them under the name of Form Extractor and Intelligent Form Extractor. Both activities can extract information from fixed form documents based on predefined templates, the difference being that the Intelligent Form Extractor can also be configured to interpret fields that are signed or handwritten. You can extract information from any type of field, including tables and create custom table extraction rules by using the Template Manager wizard.
While using the Intelligent Form Extractor activity, if the number of handwritten fields might have been exceeded, then a warning is displayed directly in the workflow. This does not stop the user from running the workflow.
UseVisualAlignment that can be used for complex layouts where it is easier for users to write regular expressions based on how words are visually
organized on lines, ignoring any sentence, paragraph, or layout group otherwise identified in the document.
You can define a regular expression for identifying the table area, a regular expression for identifying a table row in that area, and regular expressions for identifying specific columns in the table rows.
The Present Validation Station and its wizard come with many new and improved features.
The Validation Station wizard now has a new button named Discard changes. You can use it for confirming or dismissing any changes done in Validation Station. The function can be used on each document type individually.
The wizard also has a new option named Show Suggestions that allows you to select one value from multiple candidates if the used extractors report multiple possible values.
f+a, allowing you to add a new value in a multiple values field.
Improvements have been made on the Digitize Document activity that can now better identify the check boxes in a document.
This activity also has a new option named ForceApplyOCR. When selected, it applies the OCR engine to all the pages of the document, including native PDF.
The Data Extraction Scope activity can now automatically read Extractor capabilities (internal taxonomies) if the Extractor declares them. This simplifies the configuration step by exposing the extractor's known fields. The Machine Learning Extractor now supports this new functionality, making it very easy to use and configure.
The Export Extraction Results activity received a new option named IncludeConfidence. If selected, the confidence level is provided.
The extraction and configuration wizards now support bulk field selection for document types and table fields.
Release Date: 14 January 2020
- Fixed an issue that was causing the Validation Station wizard to display incorrectly the table preferences, when using the Extract new table option.
- Fixed an issue that was returning an error when Validation Station wizard was run with Callout activity chained before or after it. Now, the activity runs as expected.
- Fixed an issue that was causing the Data Extraction Scope activity to throw an error when it was run with a customized machine culture and the FormatValuesIfPossible option selected. Now, the activity runs as expected.
- Fixed an issue that was causing some performance issues when large amounts of text were selected in the Text View option of the Validation Station wizard. Now, the Text View option displays the text as expected.
- Fixed an issue that was causing the Data Extraction Scope activity to throw an error when it was run with an extractor without an internal taxonomy set and a new field was added in the project’s taxonomy. Now, the activity runs as expected.
- On certain machines, rotated documents were not displayed properly when using the Validation Station.
Release Date: 6 December 2019
-
Major updates occurred for the UiPath.IntelligentOCR.Activities package. All activities used for working with FineReader and FlexiCapture Abbyy product families were moved into a separate package named UiPath.Abbyy.Activities. This has led to a breaking change for the UiPath.IntelligentOCR.Activities package, which caused the version to skip ahead from v3.1.0 to v4.0.0. Here are the activities moved from the UiPath.IntelligentOCR.Activities package into the UiPath.Abbyy.Activities:
- The UiPath.Abbyy.Activities package cannot be used with versions lower than v19.11 for the UiPath.UIAutomation.Activities package and lower than v4.0.0 for the UiPath.IntelligentOCR.Activities package.
- If after updating a workflow to the new UiPath.IntelligentOCR.Activities v4.0.0 and UiPath.Abbyy.Activities v1.0.0 you encounter runtime validation errors, please force a new save on the
.xamlfile by making a small change and then reverting it. This might occur for workflows using FlexiCapture activities. - Workflows created or upgraded to UiPath.IntelligentOCR.Activities v4.0.0 cannot be downgraded to a lower UiPath.IntelligentOCR.Activities version.
Release Date: 8 November 2019
New exciting features and improvements are brought to you with this release.
A new activity meant to help you better organize and manage your trainable classifiers is available: Keyword Based Classifier Trainer. This activity can be used only together with the Train Classifiers Scope activity.
The Validation Station wizard received an important upgrade and is now available for you to explore its maximum potential. This wizard becomes available only when the Present Validation Station activity is used in a workflow. You can use the upgraded version for benefiting from a new user-friendly interface, navigating through the document while using the keyboard shortcuts, or selecting one or multiple words or a custom area. You can easily mark a field as missing, extract new data, edit a table, or extract a new table. All these marvelous things can be done with the Validation Station wizard while using a dark theme.
One of the improvements included in this release is that the Keyword Based Classifier activity received a new parameter named LearningData. Besides specifying where the learning file data are located, you can now also use the string containing the serialized classifier data. This activity was enhanced with a wizard named Manage Keyword Based Classifier Learning that can be used for configuring and managing the keywords used for identifying specific document types.
Both the Keyword Based Classifier and Keyword Based Classifier Trainer activities are now able to manage multiple keywords. After the keyword sets are selected, the extraction is based on a full match of the selected words.
Another great improvement is that the DocumentObjectModel output, included in the Digitize Document activity, can now support word polygons, besides word horizontal boxes.
The Taxonomy Manager wizard received a new scrolling bar that incorporates all UI elements and it provides a better user experience.
Data Extraction Scope, Train Extractors Scope, Train Classifier Scope, and Classify Document Scope activities are now arranging their extractors and classifiers in horizontal order, replacing the previous vertical order.
The Regex Based Extractor activity has been improved and can now process and return multi-values. The output is visible only when the activity is used together with the Validation Station.
Four new languages, Turkish (TR), Portuguese (PT), Spanish (ES), and Spanish-Mexico (ES-MX) are available for the UiPath.IntelligentOCR.Activities package.
- Taxonomy Manager can be accessed only if you previously opened a
.xamlfile. If no files are opened when you access the Taxonomy Manager, a recording window is shown and Taxonomy Manager is displayed only after closing the recording window.
- An exception was thrown when using the Data Extraction Scope activity together with a Try Catch activity. The issue was fixed and now the activity is executed as expected.
- When a Boolean field was set to No in Validation Station, the output file should have shown the result as No but instead is showing it as missing. The issue was fixed and now the output file shows the correct result.
- Fixed incorrect number parsing that occurred when the Data Extraction Scope was trying to parse numbers in documents using a different number format than the document's culture.
- When using multiple Validation Stations, the order of the derived parts was not respected in the validated results. The issue was fixed and now the results are displaying the derived parts in the same order they were introduced.
- Differences between the boxes with custom selection occurred when the results of a Validation Station were run through a second Validation Station. The issue was fixed and now there are no differences between boxes with custom selection.
- When the Digitize Document activity was used together with Microsoft Azure Computer Vision OCR engine, the rotation was not working when HandwritingRecognition parameter was set as True. The issue was fixed and now the information is processed correctly.
- When using Digitize Document activity, an error occurred when trying to process images with a lot of text. The bug was fixed by improving the scaling process.
- Fixed an issue that was throwing when trying to train the Keyword Based Classifier activity in the training scope and the extraction was run without a classification reference. The issue was fixed and now the fact that there is no learning information is only logged, not thrown as an error.
- An error was thrown when using the FlexiCapture Extractor activity and the same name was given to both a table column and a field. The issue was fixed and the
.fcdotfile is now processed as expected.
