AIF-C01 Applications of Foundation Models Practice Question
A company is using Amazon Bedrock to generate marketing copy. They want to evaluate the quality of the generated text. Which metric is MOST suitable for assessing the relevance and coherence of the content?
⚠ Common exam trap
AWS often tests the distinction between metrics designed for translation (BLEU) versus summarization/generation (ROUGE), leading candidates to mistakenly choose BLEU for coherence evaluation when ROUGE is the correct choice for recall-based content assessment.

Correct answer & explanation
✓
ROUGE-N
ROUGE-N (Recall-Oriented Understudy for Gisting Evaluation) measures the overlap of n-grams between generated text and reference text, making it suitable for assessing relevance and coherence in content generation tasks like marketing copy. It evaluates how well the generated text captures key phrases and maintains logical flow, which aligns with the need to assess content quality beyond simple factual accuracy.
