A support team wants to classify free-text customer reviews as positive, negative or neutral. Which service should it use?
Show answer and explanation
Answer: A
Sentiment analysis is a prebuilt Azure AI Language feature. It returns an overall score and label for the document plus per-sentence results, so a long review with mixed feelings can be broken down rather than reduced to one verdict. That maps directly onto positive, negative and neutral triage. Speech handles audio, Translator converts languages, and Bot Service provides conversational channels, none of which score opinion in written text.
Why the other options are wrong
- B. Speech converts between spoken audio and text; it does not classify the opinion expressed in text.
- C. Translator changes the language of text and leaves sentiment unmeasured.
- D. Bot Service hosts conversational experiences and provides no text analytics.
