 # Experimental Finnish language model for spaCy
 
 Finnish language model for [spaCy](https://spacy.io/). The model does POS tagging, dependency parsing, word vectors, noun phrase extraction, token frequencies, morphological features and lemmatization. The morphological features and lemmatization are based on [Voikko](https://voikko.puimula.org/).

 ### What about named entity recognizer (NER)?
 
-An earlier version of this script optinally trained a NER model, but
-the current version does not. Mostly because the model was never very
-good and the training data potentially has licensing issues.
+The [feature branch
+feature/ner](https://github.com/aajanki/spacy-fi/tree/feature/ner) has
+training scripts for a NER model. It's not merged in the main branch
+because the accuracy is quite poor.
