NameTag

NameTag is an open-source tool for named entity recognition (NER). NameTag identifies proper names in text and classifies them into predefined categories, such as names of persons, locations, organizations, etc. NameTag 2 recognizes nested entities (embedded entities) of arbitrary depth.

For Czech, it recognizes a complex hierarchy of categories. The English model, which is trained on CoNLL-2003 NER annotations (Sang and De Meulder 2003), distinguishes the following four NER classes: person, organisation, location and miscellaneous.

The trained model for Czech is available for through LINDAT: Czech Models (CNEC) for NameTag. A user manual is also available.
