Cohen","Mirella Lapata"],"abstract":"Single document summarization is the task of producing a shorter version of a\ndocument while preserving its principal information content. In this paper we\nconceptualize extractive summarization as a sentence ranking task and propose a\nnovel training algorithm which globally optimizes the ROUGE evaluation metric\nthrough a reinforcement learning objective. We use our algorithm to train a\nneural summarization model on the CNN and DailyMail datasets and demonstrate\nexperimentally that it outperforms state-of-the-art extractive and abstractive\nsystems when evaluated automatically and by humans.","url_abs":"http://arxiv.org/abs/1802.08636v2","url_pdf":"http://arxiv.org/pdf/1802.08636v2.pdf","source":{"archive":"pwc-archive (Hugging Face), CC BY-SA 4.0","snapshot":"2025-07-28","licence_url":"https://creativecommons.org/licenses/by-sa/4.0/legalcode","row_kind":"abstracts"},"code_links":[{"paper_slug":"ranking-sentences-for-extractive","repo_url":"https://github.com/shashiongithub/Refresh","is_official":1,"mentioned_in_paper":1,"mentioned_in_github":0,"framework":"tf","reach":{"status":"ok","spdx":"BSD-3-Clause"}}],"tasks":[{"task_slug":"document-summarization","task_name":"Document Summarization"},{"task_slug":"extractive-summarization","task_name":"Extractive Summarization"},{"task_slug":"extractive-document-summarization","task_name":"Extractive Text Summarization"},{"task_slug":"reinforcement-learning","task_name":"Reinforcement Learning"},{"task_slug":"reinforcement-learning-1","task_name":"Reinforcement Learning (RL)"},{"task_slug":"sentence","task_name":"Sentence"},{"task_slug":"reinforcement-learning-2","task_name":"reinforcement-learning"}],"methods":[],"datasets_introduced":[],"methods_introduced":[],"results":[{"leaderboard":"/sota/extractive-document-summarization-on-cnn","task":"Extractive Text Summarization","dataset":"CNN / Daily Mail","model":"REFRESH","rank_in_archive_order":14,"of":15,"metrics":{"ROUGE-1":"40.0","ROUGE-2":"18.2","ROUGE-L":"36.6"},"uses_additional_data":false}],"syntology":{"atlas_url":"https://app.syntology.ai/?focus=1802.08636","mcp":{"get_harvested_code_for_paper":{"arxiv_id":"1802.08636"}},"developers":"https://syntology.ai/developers","read_at":"2026-09-24T18:15:14+00:00","read_at_is":"when the build read Syntology's graph, not when any sample ran","claim":"Per-sample execution status on synthesized fixtures; not a correctness claim about the paper.
