How this summarizer works
The tool uses an extractive summarization method. It scores sentences using keyword frequency, position, selected focus terms, sentence length, dates, names, and numbers. The highest scoring sentences become the summary.
Formula used
Sentence score = normalized keyword importance + focus boosts + optional fact boosts + position weight − filtering penalties. Selected sentences are ranked, then optionally returned in their original order.
