Our system builds on the\nstatistical and empirical observations made on training and development data.\nWe found that modifiers of event nuggets tend to have unique syntactic\ndistribution. Their parts-of-speech tags and dependency relations provides them\nessential characteristics that are useful in identifying their span and also\ndefining their types and realis status. We further found that the joint\nmodeling of event span detection and realis status identification performs\nbetter than the individual models for both tasks. Our simple system designed\nusing minimal features achieved the micro-average F1 scores of 57.72, 44.27 and\n42.47 for event span detection, type identification and realis status\nclassification tasks respectively. Also, our system achieved the CoNLL F1 score\nof 27.20 in event coreference resolution task.","url_abs":"http://arxiv.org/abs/1711.02162v2","url_pdf":"http://arxiv.org/pdf/1711.02162v2.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":"tamu-at-kbp-2017-event-nugget-detection-and","repo_url":"https://github.com/prafulla77/TAC-KBP-2017-Participation","is_official":1,"mentioned_in_paper":1,"mentioned_in_github":0,"framework":"none","reach":null}],"tasks":[{"task_slug":"coreference-resolution","task_name":"Coreference Resolution"},{"task_slug":"event-coreference-resolution","task_name":"Event Coreference Resolution"},{"task_slug":"coreference-resolution-1","task_name":"coreference-resolution"}],"methods":[],"datasets_introduced":[],"methods_introduced":[],"results":[],"syntology":{"syntology_url":null,"atlas_url":null,"mcp":null,"developers":"https://syntology.ai/developers"},"arxiv_metadata":null,"syntology_extracted_results":null}
