deberta-xlarge-chinese-erlangshen-ud-goeswith
Model Description
This is a DeBERTa(V2) model pre-trained on Chinese texts (both simplified and traditional) for POS-tagging and dependency-parsing (using goeswith
for subwords), derived from deberta-xlarge-chinese-erlangshen-upos.

This model does not have enough activity to be deployed to Inference API (serverless) yet. Increase its social
visibility and check back later, or deploy to Inference Endpoints (dedicated)
instead.
