Subdomain 1.3: Identify AI workloads
1.A retailer feeds thousands of product reviews into an AI service and receives a score for each review indicating whether the reviewer's opinion is positive, negative, neutral, or mixed. Which text analysis technique is being used?
- A.Key phrase extraction
- B.Sentiment analysis
- C.Entity recognition
- D.Text summarization
Show answer & explanation
Correct answer: B — Sentiment analysis
- A. Key phrase extraction returns the main topics or concepts mentioned in text, not a judgment about whether the tone of the text is positive or negative.
- B. Sentiment analysis is correct because it evaluates text and assigns a positive, negative, neutral, or mixed opinion score, which is exactly the output the retailer is receiving for each review.
- C. Entity recognition identifies and categorizes items such as people, places, or products mentioned in text, rather than scoring the overall opinion expressed.
- D. Text summarization condenses a document into a shorter version of its content, which does not produce a positive-or-negative opinion score.
