Google Cloud Professional Machine Learning Engineer — Question 87

You work for a company that provides an anti-spam service that flags and hides spam posts on social media platforms. Your company currently uses a list of 200,000 keywords to identify suspected spam posts. If a post contains more than a few of these keywords, the post is identified as spam. You want to start using machine learning to flag spam posts for human review. What is the main advantage of implementing machine learning for this business case?

Answer options

• A. Posts can be compared to the keyword list much more quickly.
• B. New problematic phrases can be identified in spam posts.
• C. A much longer keyword list can be used to flag spam posts.
• D. Spam posts can be flagged using far fewer keywords.

Correct answer: B

Explanation

The correct answer is B because machine learning can analyze patterns in data, allowing it to identify new phrases that may indicate spam, beyond just the predefined keywords. Options A, C, and D focus on the speed or size of the keyword list, which do not leverage the full potential of machine learning's ability to recognize evolving spam tactics.
