Latvian morphosyntactic parser

This model is a Latvian joint morphosyntactic parser based on AiLab-IMCS-UL/lv-deberta-base. It predicts UPOS, XPOS, morphological features, lemmas, dependency heads, and dependency relations in a unified multi-task architecture.

The model was trained and evaluated on the Latvian Universal Dependencies Treebank from UD v2.17.
