Here we describe Chrono, a hybrid rule-based and machine learning system that identifies temporal expressions in text and normalizes them into the SCATE schema. After minor parsing logic adjustments, Chrono has emerged as the top performing system for SemEval 2018 Task 6: Parsing Time Normalizations.","url_abs":"https://aclanthology.org/S18-1012","url_pdf":"https://aclanthology.org/S18-1012.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":[],"tasks":[{"task_slug":"machine-learning","task_name":"BIG-bench Machine Learning"},{"task_slug":"temporal-information-extraction","task_name":"Temporal Information Extraction"},{"task_slug":"timex-normalization","task_name":"Timex normalization"}],"methods":[],"datasets_introduced":[],"methods_introduced":[],"results":[{"leaderboard":"/sota/timex-normalization-on-pnt","task":"Timex normalization","dataset":"PNT","model":"Chrono","rank_in_archive_order":3,"of":3,"metrics":{"F1-Score":"0.70"},"uses_additional_data":false}],"syntology":{"atlas_url":null,"mcp":null,"developers":"https://syntology.ai/developers"},"arxiv_metadata":null,"syntology_extracted_results":null}
