Evaluate AI Summarization Quality from YouTube Transcripts

This n8n workflow evaluates the accuracy and faithfulness of AI-generated summaries based on YouTube video transcripts. It uses a scoring system to assess the quality of summaries produced by language models.

n8n

The workflow begins by downloading a YouTube transcript from Google Drive and extracting its content. An AI model generates a summary, which is then evaluated against the original transcript using specific criteria such as instruction adherence, groundedness, conciseness, and fluency. The evaluation assigns a score to the summary, indicating its quality. This score helps in identifying how well the AI model aligns with the source material and instructions.
