The CLASSLA-Stanza model for lemmatisation of standard Serbian 2.1

The model for lemmatisation of standard Serbian was built with the [CLASSLA-Stanza tool](https://github.com/clarinsi/classla) by training on the [SETimes.SR training corpus](http://hdl.handle.net/11356/1200) combined with the [Serbian non-standard training corpus ReLDI-NormTagNER-sr](http://hdl.handle.net/11356/1794) and using the [srLex inflectional lexicon](http://hdl.handle.net/11356/1233). The estimated F1 of the lemma annotations is ~98.02. The model is available for download from the CLARIN.SI repository.
