AI-900Domain 4: Describe Features of Natural Language Processing Workloads on AzureNLP & SpeechhardSingle choice
A chatbot must understand that 'Book a table for Friday' means intent=Reserve with entity date=Friday. Which Azure AI Language feature extracts intents and entities from utterances?
A.Text analytics sentiment
Sentiment measures opinion polarity — not intent extraction.
B.Conversational language understanding (CLU)
Utterance → intent + entities = CLU. Correct.
C.Question answering
Q&A retrieves answers, not action intents.
D.Text summarization
Summarization condenses text — unrelated to intents.
Why this answer
CLU (the successor to LUIS) trains on utterances to predict intents and extract entities — the engine for task-driven bots. Question answering matches questions to answers in knowledge bases; summarization condenses text.
