However, these methods suffer\nfrom penalizing grammatical edits that are correct but not in the gold\nstandard. We show that reference-less grammaticality metrics correlate very\nstrongly with human judgments and are competitive with the leading\nreference-based evaluation metrics. By interpolating both methods, we achieve\nstate-of-the-art correlation with human judgments. Finally, we show that GEC\nmetrics are much more reliable when they are calculated at the sentence level\ninstead of the corpus level. We have set up a CodaLab site for benchmarking GEC\noutput using a common dataset and different evaluation metrics.","url_abs":"http://arxiv.org/abs/1610.02124v1","url_pdf":"http://arxiv.org/pdf/1610.02124v1.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":"theres-no-comparison-reference-less","repo_url":"https://github.com/cnap/grammaticality-metrics","is_official":1,"mentioned_in_paper":1,"mentioned_in_github":0,"framework":"none","reach":null}],"tasks":[{"task_slug":"benchmarking","task_name":"Benchmarking"},{"task_slug":"grammatical-error-correction","task_name":"Grammatical Error Correction"},{"task_slug":"sentence","task_name":"Sentence"}],"methods":[],"datasets_introduced":[],"methods_introduced":[],"results":[],"syntology":{"atlas_url":"https://app.syntology.ai/?focus=1610.02124","mcp":null,"developers":"https://syntology.ai/developers"},"arxiv_metadata":null,"syntology_extracted_results":null}
