CompTIA DataX (DY0-001) — Question 14

A data analyst is analyzing data and would like to build conceptual associations. Which of the following is the best way to accomplish this task?

Answer options

• A. n-grams
• B. NER
• C. TF-IDF
• D. POS

Correct answer: A

Explanation

The correct answer is A, as n-grams are used to identify and extract sequences of 'n' items from the text, which helps in understanding associations. Options B (NER), C (TF-IDF), and D (POS) serve different purposes such as named entity recognition, term frequency-inverse document frequency, and part-of-speech tagging, but do not specifically focus on creating conceptual associations.
