Which technology enables machines to understand human language and is used in phishing detection and threat text analysis?

• A. OCR
• B. Image Recognition
• C. NLP
• D. Data Mining

Answer: (C)

Natural language processing is the technology that lets machines understand and work with human language. In phishing detection and threat text analysis, NLP analyzes the content of emails, messages, and reports to extract meaning, identify suspicious patterns, and determine whether the text indicates a threat or fraud. It handles tasks like recognizing keywords and phrases, parsing sentence structure, and categorizing content to flag risky communications, often combining linguistic clues with other signals for better accuracy.

OCR is about turning images of text into machine-readable text, not about interpreting meaning. Image recognition focuses on identifying objects or scenes in images, not language. Data mining looks for patterns in large datasets, but it isn’t specialized for understanding and analyzing human language the way NLP is.
