Frequently Asked Questions
What is extractive summarization?
Extractive summarization selects and extracts the most informative, statistically significant sentences directly from the source text, preserving exact quotes without hallucinations.
How does it differ from abstractive summarization?
Abstractive summarization paraphrases and rewrites content using generative AI, while extractive summarization preserves original phrasing and avoids factual drift.
