In addition to the tagset, we\ndevelop a mapping from 25 different treebank tagsets to this universal set. As\na result, when combined with the original treebank data, this universal tagset\nand mapping produce a dataset consisting of common parts-of-speech for 22\ndifferent languages. We highlight the use of this resource via two experiments,\nincluding one that reports competitive accuracies for unsupervised grammar\ninduction without gold standard part-of-speech tags.","url_abs":"http://arxiv.org/abs/1104.2086v1","url_pdf":"http://arxiv.org/pdf/1104.2086v1.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":"a-universal-part-of-speech-tagset","repo_url":"https://github.com/slavpetrov/universal-pos-tags","is_official":0,"mentioned_in_paper":0,"mentioned_in_github":1,"framework":"none","reach":{"status":"ok","spdx":"CC-BY-SA-4.0"}}],"tasks":[],"methods":[],"datasets_introduced":[],"methods_introduced":[],"results":[],"syntology":{"syntology_url":"https://syntology.ai/paper/1104.2086","atlas_url":"https://app.syntology.ai/?focus=1104.2086","mcp":null,"developers":"https://syntology.ai/developers"},"arxiv_metadata":null,"syntology_extracted_results":null}
