This is a trained model for the supervised machine learning tool NameTag 3 (https://ufal.mff.cuni.cz/nametag/3/). NameTag 3 is an open-source tool for both flat and nested named entity recognition (NER). NameTag 3 identifies proper names in text and classifies them into a set of predefined categories, such as names of persons, locations, organizations, etc. The model was trained jointly on 21 flat NE corpora of 17 languages: Arabic, Chinese, Croatian, Czech, Danish, Dutch, English, German, Maghrebi Arabic French, Norwegian Bokmaal, Norwegian Nynorsk, Portuguese, Serbian, Slovak, Spanish, Swedish, and Ukrainian.
