- ALanguage Understanding (LUIS)
- BPersonally Identifiable Information (PII) Detection
- CKey Phrase Extraction
- DSentiment Analysis
Show answer & explanationAnswer & explanation
Correct answer: B. Personally Identifiable Information (PII) Detection
PII Detection is specifically designed to identify and redact sensitive information like credit card numbers and social security numbers, ensuring data privacy and compliance.
Why the other options are wrong
- A. Language Understanding (LUIS) is for understanding user intent and entities in conversational AI, not for general PII redaction.
- C. Key Phrase Extraction identifies main topics, not specific sensitive entities.
- D. Sentiment Analysis determines the emotional tone, not sensitive data.
PII Detection
Personally Identifiable Information (PII) Detection is an NLP capability that identifies and optionally redacts sensitive personal data from text.
- Helps with data privacy and compliance (e.g., GDPR, HIPAA).
- Can identify names, addresses, credit card numbers, email addresses, etc.
- Often used in conjunction with redaction for security.
Memory trick: Privacy Is Paramount in Data.
