+_DESCRIPTION = """SETimes_sr is a Serbian dataset annotated for morphosyntactic information and named entities.
+
+The dataset contains 3177 training samples, 395 validation samples and 319 test samples 
+across the respective data splits. Each sample represents a sentence and includes the following features:
+sentence ID ('sent_id'), sentence text ('text'), list of tokens ('tokens'), list of lemmas ('lemmas'), 
+list of Multext-East tags ('xpos_tags), list of UPOS tags ('upos_tags'),
+list of morphological features ('feats'), and list of IOB tags ('iob_tags'). The 'upos_tags' and 'iob_tags' features
+are encoded as class labels.
