技術アーキテクチャと実行の仕組み
Extractive Text Summarization Algorithm
Sentences are tokenized and scored based on term frequency-inverse document frequency (TF-IDF), sentence position, and title keyword matching to extract the most informative sentences.
Sentence_Score = Sum(Word_Frequency_Weights)技術的な制限と運用上の制約
- Uses extractive summarization (picks top original sentences) rather than generative abstractive rewriting.
主な仕様と機能

- Bullet Points & Paragraph View – Switch between key takeaways and narrative summary
- Word Count & Time Saved – Shows reduction percentage and reading time saved
