We explore this idea and introduce a greedy left-to-right\nnon-projective transition-based parser. At each parsing configuration, an\noracle decides whether to create a concept or whether to connect a pair of\nexisting concepts. The algorithm handles reentrancy and arbitrary cycles\nnatively, i.e. within the transition system itself. The model is evaluated on\nthe LDC2015E86 corpus, obtaining results close to the state of the art,\nincluding a Smatch of 64%, and showing good behavior on reentrant edges.","url_abs":"http://arxiv.org/abs/1805.09007v1","url_pdf":"http://arxiv.org/pdf/1805.09007v1.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-transition-based-algorithm-for-unrestricted","repo_url":"https://github.com/aghie/tb-amr","is_official":1,"mentioned_in_paper":1,"mentioned_in_github":0,"framework":"tf","reach":null}],"tasks":[{"task_slug":"amr-parsing","task_name":"AMR Parsing"}],"methods":[],"datasets_introduced":[],"methods_introduced":[],"results":[],"syntology":{"atlas_url":"https://app.syntology.ai/?focus=1805.09007","mcp":null,"developers":"https://syntology.ai/developers"},"arxiv_metadata":null,"syntology_extracted_results":null}
