 Adding missed labels helps improve the label precision and recall in UiPath Communications Mining. Precision is the percentage of correctly labeled verbatims out of all the verbatims that have the label applied, while recall is the percentage of correctly labeled verbatims out of all the verbatims that should have the label applied. By adding missed labels, you are increasing the recall of the label, as you are reducing the number of false negatives (verbatims that should have the label but do not). This also improves the precision of the label, as you are reducing the noise in the data and making the label more informative and consistent. Adding missed labels is one of the recommended actions that the platform suggests to improve the model rating and performance of the labels.

The most likely cause of the error is that the dictionary was not initialized. In UiPath, a dictionary must be initialized before assigning values to its keys. If you attempt to add a key-value pair to a dictionary that has not been initialized, you will encounter a runtime error.

The correct initialization can be done as follows:

PinMapping = New Dictionary(Of String, String)

Explanation of Other Options:

A. PinMapping["John Doe"]: This is the correct syntax for accessing or assigning a value to a dictionary key. There is no issue with this syntax.

B. The "John Doe" key not present: While it is true that the key might not exist, this specific error would occur only during a Get operation, not an assignment.

D. PinMapping<"John Doe">: This is incorrect syntax for working with dictionaries in UiPath.

 Document Understanding is a tool that helps you create and manage documents for your automation scenarios in the UiPath ecosystem. It allows you to process and extract data from multiple document types in an open, extensible, and versatile environment. The framework consists of components such as Taxonomy, Digitization, Data Extraction, Data Extraction Validation, Data Extraction Training, and Data Consumption, and enables you to customize and train your own algorithms12.
