ing labeled data is essential for training and test. A wide variety of datasets exist for part-of-speech tagging and/or NER. The Universal Dependencies (UD) dataset (Nivre et al., 2016b) has POS tagged corpora in 92 languages at the time of this writing, as do the Penn Treebanks in English, Chinese, and Arabic. OntoNotes has corpora labeled for named entities in English, Chinese, and Arabic (Hovy et al., 2006) . Named entity tagged corpora also available in particular domains, such as for biomedical (Bada et al., 2012) and literary text (Bamman et al., 2019).
