Question 6

A restaurant chain wants to build a voice-powered ordering system for its drive-through. The system must understand when a user wants to place an order, modify an existing order, or cancel an order. It also needs to extract specific details like the menu item name and quantity from the user's speech. Which Azure AI Language feature should they use to handle both intent recognition and entity extraction?

Accepted Answer

Conversational Language Understanding (CLU). Conversational Language Understanding (CLU) is the correct choice because it is specifically designed to handle both intent recognition (e.g., 'place order', 'modify order', 'cancel order') and entity extraction (e.g., menu item name, quantity) from natural language utterances. CLU uses a pre-built or custom model to map user input to intents and extract detailed entities, making it ideal for a voice-powered ordering system that needs to understand complex commands.

Question 7

A hospital wants to automatically anonymize patient medical records by removing all personally identifiable information (PII) such as names, dates, and social security numbers from unstructured text notes. Which Azure AI Language feature should they use?

Accepted Answer

Named entity recognition (NER). Named entity recognition (NER) is the correct Azure AI Language feature because it is specifically designed to identify and categorize entities in unstructured text, including PII categories such as names, dates, and social security numbers. The hospital can use NER's pre-built PII detection model to automatically locate and redact these sensitive elements from patient notes, meeting their anonymization requirement.

Question 8

A university wants to build a chatbot that can answer questions about its admission procedures. The chatbot should retrieve answers directly from a set of official PDF documents containing policies and FAQs. Which Azure AI Language feature should they use to implement this?

Accepted Answer

Custom question answering. Custom question answering (C) is the correct choice because it allows the university to ingest official PDF documents and create a knowledge base of question-answer pairs. The chatbot can then retrieve answers directly from this curated content, making it ideal for domain-specific, document-based Q&A scenarios like admission procedures.

Language detection

Question 9

A legal department needs to automatically extract specific entities from contracts, such as 'Effective Date', 'Governing Law', and 'Payment Terms'. They have 500 manually labeled contract clauses that specify which text spans correspond to each entity. Which Azure AI Language feature should they use to build this custom entity extraction solution?

Accepted Answer

Custom Named Entity Recognition (Custom NER). Custom Named Entity Recognition (Custom NER) is the correct choice because it allows you to train a model on your own labeled data (the 500 manually labeled contract clauses) to extract domain-specific entities like 'Effective Date', 'Governing Law', and 'Payment Terms' that are not covered by prebuilt models. This feature uses a custom trained model to identify and classify text spans according to your defined schema.

Answer

Prebuilt Named Entity Recognition (NER)

Answer

Key phrase extraction

Answer

Custom text classification

Question 10

A legal department needs to automatically extract specific types of information from court documents, such as the names of plaintiffs and defendants, dates of hearings, and names of presiding judges. The department has a large set of unlabeled documents but does not have any manually tagged examples. Which Azure AI Language feature should they use?

Accepted Answer

Named Entity Recognition (NER). Named Entity Recognition (NER) is the correct choice because it is a pre-built Azure AI Language feature designed to automatically identify and extract specific categories of information—such as person names, dates, and organizations—from unstructured text without requiring any labeled training data. The legal department's need to extract plaintiffs, defendants, hearing dates, and judges aligns directly with NER's out-of-the-box capabilities for common entity types like Person, Date, and Organization.

Question 11

A news agency wants to build a system that can automatically generate a short headline for each news article. The system should select the most important sentence from the article as the headline. Which Azure AI Language feature should they use?

Accepted Answer

B: Extractive summarization. Extractive summarization is the correct Azure AI Language feature because it identifies and extracts the most important sentences from a document, which directly matches the requirement to select the most important sentence as a headline. Unlike key phrase extraction, which returns individual words or short phrases, extractive summarization returns complete sentences ranked by relevance, making it ideal for headline generation.

Answer

A: Key phrase extraction

Answer

C: Entity recognition

Answer

D: Sentiment analysis

Question 12

A hospital wants to automatically extract patient symptoms and medication names from clinical notes. They have a set of pre-defined categories for symptoms and medications, and they have manually labeled a few hundred sentences to indicate which text spans belong to each category. Which Azure AI Language feature should they use to build this custom entity extraction solution?

Accepted Answer

Custom entity extraction. Custom entity extraction (D) is the correct choice because the hospital needs to identify specific text spans (symptoms and medication names) based on their own pre-defined categories, using a small set of manually labeled sentences for training. This is exactly what Azure's custom named entity recognition (NER) feature does—it allows you to train a model to extract custom entities from unstructured text, tailored to your domain-specific labels.

Answer

Pre-built entity recognition

Answer

Key phrase extraction

Answer

Custom text classification

Question 13

A legal firm needs to automatically extract case-specific entities such as 'docket number', 'plaintiff attorney', and 'court name' from legal documents. They have a small set of manually labeled examples for each entity. Which Azure AI Language feature should they use to build this custom entity extraction solution?

Accepted Answer

Custom named entity recognition (NER). Custom named entity recognition (NER) allows you to train a model with your own labeled examples to extract domain-specific entities like 'docket number' and 'plaintiff attorney'. Prebuilt entity extraction only recognizes common, generic entities (e.g., person, location) and cannot be customized for legal case-specific terms. This makes custom NER the correct choice for building a tailored extraction solution with a small set of manually labeled data.

Answer

Prebuilt entity extraction

Answer

Key phrase extraction

Answer

Sentiment analysis

Question 14

A medical transcription service wants to automatically identify and extract medical terms such as diagnoses, medications, and procedures from doctor's notes. The notes are unstructured text. They want to use a pre-trained Azure AI Language feature that can understand medical terminology. Which feature should they use?

Accepted Answer

Named Entity Recognition (NER) for healthcare. B is correct because the medical transcription service needs to extract specific medical entities (diagnoses, medications, procedures) from unstructured doctor's notes. Azure AI Language's Named Entity Recognition (NER) for healthcare is a pre-trained model specifically designed to identify and categorize medical terminology, including conditions, treatments, and medications, directly from clinical text without requiring custom training.
