NKJP model for TnT Tagger
Here you can download the model for TnT tagger, which was created by training the tagger with the one-million manually annotated subcorpus of the Polish National Corpus. The model is available under BSD license. The downloaded file has to be unzipped.
To use the TnT tagger, you need a copy from its author (see his webpage). To run the tagger, use:
tnt nkjp <nazwa_pliku>
The input file needs to be tokenized into sentences (separated with two end-of-line characters) and words in the way the Polish National Corpus is tokenized. (Use Morfeusz if unsure). The tagger's quality is around 88%.
