Coordinations in the Penn Treebank\nare missing internal structure in many cases, do not include explicit marking\nof the conjuncts and contain various errors and inconsistencies. In this work,\nwe initiated manual annotation process for solving these issues. We identify\nthe different elements in a coordination phrase and label each element with its\nfunction. We add phrase boundaries when these are missing, unify\ninconsistencies, and fix errors. The outcome is an extension of the PTB that\nincludes consistent and detailed structures for coordinations. We make the\ncoordination annotation publicly available, in hope that they will facilitate\nfurther research into coordination disambiguation.","url_abs":"http://arxiv.org/abs/1606.02529v1","url_pdf":"http://arxiv.org/pdf/1606.02529v1.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":"coordination-annotation-extension-in-the-penn","repo_url":"https://github.com/Jess1ca/CoordinationExtPTB","is_official":1,"mentioned_in_paper":1,"mentioned_in_github":1,"framework":"none","reach":{"status":"ok"}}],"tasks":[],"methods":[],"datasets_introduced":[],"methods_introduced":[],"results":[],"syntology":{"atlas_url":"https://app.syntology.ai/?focus=1606.02529","mcp":null,"developers":"https://syntology.ai/developers"},"arxiv_metadata":null,"syntology_extracted_results":null}
