PII Can not detect for Spanish country

Hi Mohsin Khan,

Thank you for contacting Q&A Forum. I would like to provide my findings and proposed solution:

The Azure AI Language PII detection Preview API is still under development and may undergo changes. It is not recommended for production use. Customers should wait for the General Availability (GA) release, which will offer stable features and full support. For more information on the PII detection feature and its current capabilities, you can refer to the official documentation:

Government and country/region-specific identification

Azure AI Language's PII detection service supports Spanish and can identify entities like Spain's Documento Nacional de Identidad (DNI) when presented in isolation. However, its accuracy diminishes when such identifiers are embedded within longer, unstructured text.

This limitation arises because the underlying models may not effectively recognize certain PII types in complex contexts. To enhance detection, it's advisable to specify the language explicitly in your API requests, adjust confidence score thresholds, preprocess text to isolate potential PII elements, or supplement with custom logic like regular expressions tailored to Spanish identification formats

Kindly let me know if this work for you and please let me know if you have any further question.

If I have answered your question, please accept this as answer as a token of appreciation and don't forget to thumbs up for "Was it helpful"!

Best regards,
