Assistance Required with RecognizePiiEntitiesAsync in TextAnalyticsClient for Custom PII Categories

Question

Dear Microsoft Azure Support Team,

 

I hope this message finds you well.

 

I am currently working with the RecognizePiiEntitiesAsync method of the TextAnalyticsClient service in Azure. While using this service, I receive a collection of PiiEntityCollection that includes categories such as PersonType, Age, and DateTime. However, I am encountering an issue where these specific categories cannot be selected as PiiEntityCategories when defining the list of categories I want to redact.

 

Here is a brief description of the issue:

• Service: Azure Text Analytics
• Method: RecognizePiiEntitiesAsync
• Problem: The returned PiiEntityCollection contains categories like PersonType, Age, and DateTime, but these categories do not appear to be available for selection when defining PiiEntityCategories for redaction purposes.

 

Could you please provide guidance or a solution on how to handle this situation? Specifically, I am looking to redact entities within these categories but am unable to do so due to their absence in the PiiEntityCategories enumeration.

 

Thank you for your assistance. I look forward to your response.

 

Best regards,

Hello, I’ve implemented a temporary solution that works very well. I’ve added categories such as PersonType, Quantity, and DateTime directly into the PiiEntityCategories list, even though these categories are not available for selection when defining PiiEntityCategories for redaction purposes. Here’s my solution:

var piiEntityCategories = new List<PiiEntityCategory>();

switch (yourCondition)

{

case Case1:

piiEntityCategories.Add(EntityCategory.DateTime.ToString());

break;

case Case2:

piiEntityCategories.Add(EntityCategory.PersonType.ToString());

break;

case Case3:

piiEntityCategories.Add(EntityCategory.Quantity.ToString());

break;

case Case4:

piiEntityCategories.Add(PiiEntityCategory.Date);

break;

default:

// Handle default case if needed

break;

}

Bonjour Nacim,

Merci d'avoir sollicité la communauté Q&A France.

Voici deux liens qui pourraient vous être utiles:

• How can I allow certain entities (e.g., names, organizations) in Azures PII Entity Recognition method so that they are not recognized/masked?
• PII Identification with Azure Cognitive Services in C#

A bientôt
