This dataset is based on 7,939 Croatian tweets that were segmented into sentences, tokens, and annotated with normalized forms, lemmas, MULTEXTEast tags (XPOS), UPOS tags and morphological features, and named entities.

The dataset contains 6339 training samples (tweets), 815 validation samples and 785 test samples. 
Each sample represents a sentence and includes the following features: sentence ID ('sent\_id'), 
list of tokens ('tokens'), list of normalised tokens ('norms'), list of lemmas ('lemmas'), list of UPOS tags ('upos\_tags'), 
list of MULTEXT-East tags ('xpos\_tags), list of morphological features ('feats'), 
and list of named entity IOB tags ('iob\_tags'), which are encoded as class labels.
