In UiPath's Taxonomy Manager, the "Possible values" rule should be used when a text field can have one of several predefined values. This ensures that the extracted data is validated against a list of acceptable values, helping to maintain consistency and accuracy during the extraction process. It is particularly useful for fields such as status indicators or categorical fields where only a limited set of options is valid.

In UiPath Communications Mining, general fields that are trained from scratch require user-defined inputs and training data, making them highly customizable but dependent on the specific data provided by the user. In contrast, pre-trained general fields are based on predefined rules and training models developed by UiPath. These pre-trained fields offer out-of-the-box functionality and are optimized for common use cases, whereas user-trained fields offer more flexibility to meet specific business requirements.

Comprehensive and Detailed Explanation From Exact Extract:

When using theGenerative Extractorin Document Understanding, the best way to increase accuracy and reliability is byspecifying a clear output format. This helps the model understand what kind of response is expected and improves parsing consistency.

Example: "What is the invoice number? Please return in the format: InvoiceNumber: "

===========

Comprehensive and Detailed Explanation From Exact Extract:

TheDocument Classificationstep in Document Understanding identifies thetype of document(e.g., Invoice, Receipt, Contract) being processed. It uses trained classification models to assign the correct document type before extraction begins.

This is critical in cases where multiple document types are processed together.

According to the UiPath documentation portal1, the Export stage of the Document Understanding Framework is the final stage of the document processing workflow, where the extracted data is converted to a dataset or to a customized format, such as Excel, JSON, or XML. The Export stage enables you to easily export data for training ML models, using the Export files dialog box in Data Manager or Document Manager. The Export stage also allows you to export the schema of the fields and their configurations, which can be imported into a different session. The Export stage supports different export options, such as current search results, all labeled, schema, or all. The Export stage also provides validation rules, such as requiring at least 10 labeled documents or pages for each field, and at least one document for each classification option1. Therefore, option A is the correct answer, as it describes the main function and benefit of the Export stage. Option B is incorrect, as it refers to the Data Validation stage, which is the previous stage of the document processing workflow, where a human can review and correct the extracted data using the Validation Station or the Present Validation Station activities2. Option C is incorrect, as it refers to the Classification stage, which is the second stage of the document processing workflow, where the document is classified as one of the predefined document types using the Classify Document Scope activity and a classifier of choice3. Option D is incorrect, as it refers to the Digitization stage, which is the first stage of the document processing workflow, where the text is extracted out of the image document using OCR (Optical Character Recognition) using the Digitize Document activity and an OCR engine of choice.

To build custom models supported by AI Center, you can use a Python IDE or an AutoML platform of your choice. A Python IDE is a software application that provides tools and features for writing, editing, debugging, and running Python code. An AutoML platform is a service that automates the process of building and deploying machine learning models, such as data preprocessing, feature engineering, model selection, hyperparameter tuning, and model evaluation. Some examples of Python IDEs are PyCharm, Visual Studio Code, and Jupyter Notebook. Some examples of AutoML platforms are Google Cloud AutoML, Microsoft Azure Machine Learning, and DataRobot.

To use a Python IDE, you need to install the required Python packages and dependencies, write the code for your model, and test it locally. Then, you need to package your model as a zip file that follows the AI Center ML Package structure and requirements. You can then upload the zip file to AI Center and create an ML Skill to deploy and consume your model.

To use an AutoML platform, you need to sign up for the service, upload your data, configure your model settings, and train your model. Then, you need to export your model as a zip file that follows the AI Center ML Package structure and requirements. You can then upload the zip file to AI Center and create an ML Skill to deploy and consume your model.

In UiPath Communications Mining, high coverage ensures that a larger proportion of communications is classified with meaningful labels, meaning fewer communications are sent for manual review and more processes are captured for automation. This leads to more effective automation, reducing the need for human intervention and ensuring that the automation use case is fully realized.

Comprehensive and Detailed Explanation From Exact Extract:

TheValidate (Extract)component is responsible for allowing a human toreview, correct, or approve the data extractedby the robot. It typically uses thePresent Validation Stationactivity in the workflow.

This step ensures data quality before submission or processing.

The extracted data is compared against what a human user confirms as accurate.

Comprehensive and Detailed Explanation From Exact Extract:

In UiPath, when executing an activity such asClick, the timeout behavior is determined as follows:

If the Timeout property in the activity is set, that value is used.

If the Timeout is left blank, the system uses thedefault from Project SettingsunderUI Automation Modern → Timeout.

In this case (based on the second image):

TheClick activity explicitly has Timeout set to 15 seconds.

Therefore, this activity willoverridethe project-level default timeout (which is 30 seconds as seen in the first image).

Rule Applied:

Activity Timeout > Project Settings Timeout (if defined)

Hence, if thetarget element is not found, UiPath willwait for 15 seconds, as specified in the activity'sTimeout field, before throwing an error.

===========

According to the UiPath documentation, a UiPath Communications Mining taxonomy is a collection of all the labels applied to the verbatims in a dataset, structured in a hierarchical manner. Labels are the concepts and intents that you want to capture in the dataset to suit your specific objectives. When you import your taxonomy from a spreadsheet, you need to provide the label descriptions, which are the names of the labels and their level in the hierarchy. Label predictions and entity predictions are the outputs of the model training process, and they are not part of the taxonomy. Entity descriptions are the definitions of the entities that you want to extract from the verbatims, and they are not part of the taxonomy either.
