The Classify Document Scope activity in UiPath is used to classify documents supported by the Document Understanding framework. It primarily works with file formats like PDF, JPG, PNG, and other image-based formats but does not process raw or non-standard file types like .raw.

 According to the UiPath Document Understanding Process template, the best way to test the code in a development or testing environment is to create test data based on the use case developed, and use it to test both the existing and the new tests. The test data should include different document types, formats, and scenarios that reflect the real-world data that the process will handle in production. The existing tests are provided by the template and cover the main functionalities and components of the Document Understanding Process, such as digitization, classification, data extraction, validation, and export. The new tests are created by the developer to test the customizations and integrations that are specific to the use case, such as custom extractors, classifiers, or data consumption methods. The test data and the test cases should be updated and maintained throughout the development lifecycle to ensure the quality and reliability of the code.

| Step | Description |

| 1 | Click "Taxonomy Manager" in the Studio Design ribbon then click Taxonomy. |

| 2 | Create a Category by clicking "+ Category" and then click the created Category. |

| 3 | Create a Group by clicking "+ Group" and then click the created Group. |

| 4 | Create a Document Type by clicking "+ Document Type" and then click the Document Type. |

To define a document structure that the Document Understanding framework can classify and extract from, the following hierarchical structure must be created in the Taxonomy Manager :

Taxonomy Manager – Launch from the Design ribbon in Studio.

Category – Top-level classification (e.g., Financial, HR, Legal).

Group – Sub-division under a category (e.g., Invoices, Contracts).

Document Type – Specific type of document (e.g., Vendor Invoice, NDA).

This structure is required for the Classify Document Scope activity to function properly.

The correct syntax for filtering both .doc and .docx Word documents is to use the wildcard *.doc*. This matches:

.doc

.docx

Any Word file variant starting with .doc

UiPath Studio uses .NET wildcards for file filters in activities like "For Each File in Folder".

In UiPath, the Data Scientist role is primarily responsible for creating, training, and uploading machine learning models to AI Center. While RPA developers might integrate these models into workflows, it is the Data Scientist who builds and fine-tunes models, ensuring their accuracy and relevance for various use cases.

The error "Object reference not set to an instance of an object" occurs when the DataTable variable (dt_Reports) hasn't been initialized.

To fix this, use:

vb

CopyEdit

Assign dt_Reports = New System.Data.DataTable

Then, add necessary columns before adding rows.

Note: You cannot assign a new row (DataRow) without first initializing the DataTable.

Create the new label by assigning it at least once. This is the initial step to introduce a new category or classification within your data taxonomy.

Search for instances in the reviewed data where the new label should have been assigned, and apply the label accordingly. This step is crucial for maintaining consistency across your data set.

Use 'Missed Label' to find all additional missing examples in the reviewed data. This action helps in identifying and rectifying any instances that may have been overlooked during the initial review.

Check validation to ensure the label is performing as expected, and follow recommended actions if further training is required. Validation is key to assess the accuracy and performance of the new label within the system.
