+
+## Model Description
+
+This is a LLaMA model for POS-tagging, derived from [karasu-1.1B](https://huggingface.co/lightblue/karasu-1.1B). Every short-unit-word is tagged by [UPOS](https://universaldependencies.org/u/pos/) (Universal Part-Of-Speech) and [FEATS](https://universaldependencies.org/u/feat/).
+
+## How to Use
+
+```py
+from transformers import pipeline
+nlp=pipeline("upos","KoichiYasuoka/karasu-1.1B-upos",trust_remote_code=True,aggregation_strategy="simple")
+print(nlp("国境の長いトンネルを抜けると雪国であった。"))
+```
