To strengthen the training-test overlap, we collect a large\ncorpus of about 38K documents and 12.4M words which are mostly from the\nvocabulary of English-speaking preschoolers. Experiments show that with higher\ntraining-test overlap, error analysis on PreCo is more efficient than the one\non OntoNotes, a popular existing dataset. Furthermore, we annotate singleton\nmentions making it possible for the first time to quantify the influence that a\nmention detector makes on coreference resolution performance. The dataset is\nfreely available at https://preschool-lab.github.io/PreCo/.","url_abs":"http://arxiv.org/abs/1810.09807v1","url_pdf":"http://arxiv.org/pdf/1810.09807v1.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":"clustering","task_name":"Clustering"},{"task_slug":"coreference-resolution","task_name":"Coreference Resolution"},{"task_slug":"coreference-resolution-1","task_name":"coreference-resolution"}],"methods":[],"datasets_introduced":[{"slug":"preco","name":"PreCo","full_name":""}],"methods_introduced":[],"results":[],"syntology":{"atlas_url":"https://app.syntology.ai/?focus=1810.09807","mcp":null,"developers":"https://syntology.ai/developers"},"arxiv_metadata":null,"syntology_extracted_results":null}
