You need to identify the main talking points in a collection of documents.
Which type of natural language processing should you use?

Answer options

• A. entity recognition
• B. key phrase extraction
• C. sentiment analysis
• D. language detection

Correct answer: B

Explanation

The correct answer is B, key phrase extraction, as it specifically focuses on identifying the main points or phrases within the text. Option A, entity recognition, is used for identifying specific entities but does not summarize main points. Option C, sentiment analysis, evaluates emotions rather than topics, and Option D, language detection, identifies the language in use, which does not pertain to finding main talking points.
