AI-102 Practice Question: Implement knowledge mining and information extraction solutions
Your company has a large repository of scanned invoices in PDF format. You need to extract invoice number, date, total amount, and vendor name from these PDFs. Which Azure AI service should you use?
⚠ Common exam trap
A common mistake is to choose Azure AI Vision because it performs OCR on scanned PDFs, but it does not provide prebuilt models for extracting structured fields like invoice data. Azure AI Document Intelligence (formerly Form Recognizer) is the correct service as it specializes in extracting key-value pairs from forms and documents.
