ReLDI-NormTagNER-sr 2.1 is a manually annotated corpus of Serbian tweets. It is meant as a gold-standard training and testing dataset for tokenisation, sentence segmentation, word normalisation, morphosyntactic tagging, lemmatisation and named entity recognition of non-standard Serbian. Each tweet is also annotated for its automatically assigned standardness levels (T = technical standardness, L = linguistic standardness).
As an update to version 2.0, version 2.1 corrects some annotation errors and adds morphosyntactic annotations in the Universal Dependencies formalism in addition to the MULTEXT-East morphosyntactic descriptions. The corpus is now also available in CoNLL-U format.
