- A.Prebuilt sentiment analysis
- B.Custom named entity recognition trained on labeled examples from its reports
- C.Language detection
- D.Text-to-speech
Show answer and explanation
Correct answer: B. Custom named entity recognition trained on labeled examples from its reports
Why: Custom named entity recognition lets you train a model on your own labeled text to extract custom entity categories that prebuilt NER doesn't cover. Sentiment analysis measures opinions, language detection identifies the language, and text to speech produces audio.
