This paper proposes PROPALIGN, a multiple-summary-based approach for propositional salience score estimation, and releases PROPALIGNBANK, an accompanying dataset for the method with 138K alignments of over 35K propositions. We compare several approaches to salient proposition extraction in English across a broad range of spoken and written genres, and demonstrate that naively asking models for judgments leads to inconsistencies. By contrast, graded, summary-based metrics are more stable. We further observe that while single models perform worse than humans, an ensemble of models incorporating linguistic features approaches manual annotation quality ceilings. In addition, analyses of the model outputs suggest insights into how models can extract salient information with and without the use of summaries.", "url": "https://wpnews.pro/news/the-sum-of-all-summaries-propalign-for-graded-proposition-salience-evaluation", "canonical_source": "https://www.machinebrief.com/news/the-sum-of-all-summaries-propalign-for-graded-proposition-sa-hbj9", "published_at": "2026-10-15 04:00:00+00:00", "updated_at": "2026-10-15 05:53:00.129799+00:00", "lang": "en", "topics": ["natural-language-processing", "ai-research", "large-language-models", "machine-learning"], "entities": ["PROPALIGN", "PROPALIGNBANK", "arXiv"], "also_reported_by": [], "alternates": {"html": "https://wpnews.pro/news/the-sum-of-all-summaries-propalign-for-graded-proposition-salience-evaluation", "markdown": "https://wpnews.pro/news/the-sum-of-all-summaries-propalign-for-graded-proposition-salience-evaluation.md", "text": "https://wpnews.pro/news/the-sum-of-all-summaries-propalign-for-graded-proposition-salience-evaluation.txt", "jsonld": "https://wpnews.pro/news/the-sum-of-all-summaries-propalign-for-graded-proposition-salience-evaluation.jsonld"}}
