AI-102 Practice Question: Implement knowledge mining and information extraction solutions
You are building a knowledge mining solution to extract insights from a large set of PDF contracts. The solution must identify parties, dates, and monetary amounts. Which Azure AI service should you use as the primary extraction engine?
⚠ Common exam trap
Candidates often confuse Azure AI Language (custom NER) as a suitable choice for PDF extraction, overlooking that it requires pre-extracted text and lacks native PDF processing, while Azure AI Document Intelligence is the dedicated service for document-based extraction.
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Azure AI Document Intelligence
Azure AI Document Intelligence (formerly Form Recognizer) is the correct choice because it is specifically designed for document analysis and extraction of structured data such as parties, dates, and monetary amounts from PDFs and images. Its prebuilt models (e.g., the 'prebuilt-invoice' or 'prebuilt-contract' model) use optical character recognition (OCR) and deep learning to extract key-value pairs and entities from contracts without requiring custom training.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Azure AI Language (custom NER)
Why it's wrong here
Custom NER is text-based and misses layout features like tables.
- ✗
Azure AI Search with integrated vectorization
Why it's wrong here
Azure AI Search is for indexing and search, not primary extraction.
- ✗
Azure OpenAI Service with GPT-4o
Why it's wrong here
Overkill and higher cost; Document Intelligence is purpose-built.
- ✓
Azure AI Document Intelligence
Why this is correct
Designed for extracting fields from forms and documents.
