This new\nresource aims to provide training and development data for NLP methods that aim\nto adapt to unfamiliar languages. Each synthetic treebank is produced from a\nreal treebank by stochastically permuting the dependents of nouns and/or verbs\nto match the word order of other real languages. We discuss the usefulness,\nrealism, parsability, perplexity, and diversity of the synthetic languages. As\na simple demonstration of the use of Galactic Dependencies, we consider\nsingle-source transfer, which attempts to parse a real target language using a\nparser trained on a \"nearby\" source language. We find that including synthetic\nsource languages somewhat increases the diversity of the source pool, which\nsignificantly improves results for most target languages.","url_abs":"http://arxiv.org/abs/1710.03838v1","url_pdf":"http://arxiv.org/pdf/1710.03838v1.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":"the-galactic-dependencies-treebanks-getting","repo_url":"https://github.com/gdtreebank/gdtreebank","is_official":1,"mentioned_in_paper":1,"mentioned_in_github":0,"framework":"none","reach":null}],"tasks":[{"task_slug":"diversity","task_name":"Diversity"}],"methods":[],"datasets_introduced":[],"methods_introduced":[],"results":[],"syntology":{"atlas_url":"https://app.syntology.ai/?focus=1710.03838","mcp":null,"developers":"https://syntology.ai/developers"},"arxiv_metadata":null,"syntology_extracted_results":null}
