We demonstrate that both\ntasks benefit from sharing the encoding part of the network, predicting tag\nsubcategories, and using the tagger output as an input to the lemmatizer. We\nevaluate our model across several languages with complex morphology, which\nsurpasses state-of-the-art accuracy in both part-of-speech tagging and\nlemmatization in Czech, German, and Arabic.","url_abs":"http://arxiv.org/abs/1808.03703v2","url_pdf":"http://arxiv.org/pdf/1808.03703v2.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":"lemmatag-jointly-tagging-and-lemmatizing-for","repo_url":"https://github.com/hyperparticle/LemmaTag","is_official":1,"mentioned_in_paper":1,"mentioned_in_github":1,"framework":"tf","reach":null},{"paper_slug":"lemmatag-jointly-tagging-and-lemmatizing-for","repo_url":"https://github.com/jkulhanek/lemmatag","is_official":0,"mentioned_in_paper":0,"mentioned_in_github":1,"framework":"tf","reach":null}],"tasks":[{"task_slug":"lemmatization","task_name":"Lemmatization"},{"task_slug":"part-of-speech-tagging","task_name":"Part-Of-Speech Tagging"},{"task_slug":"tag","task_name":"TAG"}],"methods":[],"datasets_introduced":[],"methods_introduced":[],"results":[],"syntology":{"atlas_url":"https://app.syntology.ai/?focus=1808.03703","mcp":null,"developers":"https://syntology.ai/developers"},"arxiv_metadata":null,"syntology_extracted_results":null}
