AI-102 Practice Question: Implement knowledge mining and information extraction solutions
Your team is building a knowledge mining solution for research papers. You need to automatically categorize papers into topics and extract author names, publication dates, and references. The solution must use custom models because the papers are domain-specific. Which combination of Azure services should you use?
⚠ Common exam trap
A common mistake on the Azure AI-102 exam is choosing pre-built models (like the invoice model or generic entity extraction) thinking they can be adapted to domain-specific needs, but the question explicitly requires custom models. Always verify if the scenario demands custom training.
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's custom extraction model and Azure AI Language's custom text classification
It combines Azure AI Document Intelligence's custom extraction model to extract domain-specific fields like author names, publication dates, and references, with Azure AI Language's custom text classification to categorize research papers into topics. This pairing directly addresses the need for custom models tailored to the specialized domain, unlike pre-built or generic solutions.
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 Document Intelligence's pre-built invoice model and Azure Bot Service
Why it's wrong here
Invoice model is not for research papers; Bot Service is not needed.
- ✓
Azure AI Document Intelligence's custom extraction model and Azure AI Language's custom text classification
Why this is correct
Custom models can handle domain-specific extraction and classification.
- ✗
Azure AI Search's built-in OCR skill and a custom skill using Azure Functions
Why it's wrong here
OCR extracts text but not structured fields; custom skill is possible but not the best combination.
- ✗
Azure AI Language's pre-built entity extraction and Azure AI Search
Why it's wrong here
Pre-built models may not capture domain-specific entities.
