The annotation scheme used is similar to TimeML. TimeBankPT is the result of adapting the English corpus used in the first TempEval challenge to the Portuguese language.\r\n\r\nIn what regards the temporal relaiton type, the corpus was annotated with *six* labels, namely: BEFORE, AFTER, OVERLAP, BEFORE-OR-OVERLAP,\r\nOVERLAP-OR-AFTER and VAGUE.\r\n\r\n|           | Train | Test |\r\n|-----------|-------|------|\r\n| Documents | 162 | 20 |\r\n| Sentences | 2281  | 351  |\r\n| Words     | 60782 | 8920 |\r\n| Events    | 6790  | 1097 |\r\n| Timexs    | 1244  | 165  |\r\n| Tlinks    | 5781  | 758  |","description_withheld":null,"homepage":"http://nlx-server.di.fc.ul.pt/~fcosta/TimeBankPT/","introduced_date":"2012-05-01","introduced_date_note":null,"introduced_by":{"paper":"/paper/timebankpt-a-timeml-annotated-corpus-of","title":"TimeBankPT: A TimeML Annotated Corpus of Portuguese","first_author":"Francisco Costa","url":null},"license":{"name":"Coming soon.","url":"http://nlx-server.di.fc.ul.pt/~fcosta/TimeBankPT/#Licence-"},"modalities":[{"name":"Texts","url":"/datasets/modality/texts"}],"tasks":[{"name":"Relation Extraction","url":"/task/relation-extraction","datasets_with_task":"/datasets/task/relation-extraction"},{"name":"Temporal Tagging","url":"/task/temporal-tagging","datasets_with_task":"/datasets/task/temporal-tagging"},{"name":"Joint Event and Temporal Relation Extraction","url":"/task/joint-event-and-temporal-relation-extraction","datasets_with_task":"/datasets/task/joint-event-and-temporal-relation-extraction"},{"name":"Multi-Labeled Relation Extraction","url":"/task/multi-labeled-relation-extraction","datasets_with_task":"/datasets/task/multi-labeled-relation-extraction"}],"languages":[{"name":"Portuguese","url":"/datasets/language/portuguese"}],"variants":["TimeBankPT"],"data_loaders":[],"num_papers_in_archive":4,"source":{"archive":"pwc-archive (Hugging Face), CC BY-SA 4.0","snapshot":"2025-07-28"},"benchmarks":[{"leaderboard":"/sota/temporal-tagging-on-timebankpt","task":"Temporal Tagging","dataset_variant":"TimeBankPT","rows":1,"metrics":["F1"],"first_row_in_archive_order":{"model":"Lange et al.","paper":"/paper/adversarial-alignment-of-multilingual-models","metrics":{"F1":"75.47"},"code_links":[]},"note":"rows are the archive's own order at snapshot; nothing here re-ranks them"}],"papers_with_a_benchmark_row":[{"paper":"/paper/adversarial-alignment-of-multilingual-models","title":"Adversarial Alignment of Multilingual Models for Extracting Temporal Expressions from Text","date":"2020-05-19","rows_on_this_dataset":1,"code_links":0,"syntology":null}],"syntology_totals":{"read_at":"2026-09-24T18:15:14+00:00","papers_with_samples":0,"samples_harvested":0,"samples_ran":0,"samples_unverified":0,"pointer_only_for_licence":0,"papers_with_no_sample_that_ran":0,"note":"the per-paper counts above, summed; not a rate"},"papers_note":"The archive never published its papers-using-dataset list; these are papers with a leaderboard row on this dataset's benchmarks."}
