AI-102 Practice Question: Implement natural language processing solutions
A healthcare organization needs to redact personally identifiable information (PII) from patient records before using them for research. They have large volumes of unstructured text in multiple languages. Which Azure AI service should they use?
⚠ Common exam trap
It's easy for candidates to confuse Azure AI Language's PII detection with Azure AI Document Intelligence's data extraction capabilities, but Document Intelligence focuses on structured field extraction from forms, not redaction of PII from unstructured text.
