This model is a fine-tuned version of the tohoku-nlp/bert-base-japanese-v3, specifically optimized for Named Entity Recognition (NER) tasks. It is fine-tuned using a Japanese named entity extraction dataset derived from Wikipedia, which was developed and made publicly available by Stockmark Inc. (NER Wikipedia Dataset).

Intended Use

This model is intended for use in tasks that require the identification and categorization of named entities within Japanese text. It is suitable for various applications in natural language processing where understanding the specific names of people, organizations, locations, etc., is crucial.

How to Use

You can use this model for NER tasks with the following simple code snippet:

python

from transformers import AutoModelForTokenClassification, AutoTokenizer
import torch

model_name = "knosing/japanese_ner_model"
tokenizer = AutoTokenizer.from_pretrained("tohoku-nlp/bert-base-japanese-v3")
model = AutoModelForTokenClassification.from_pretrained(model_name)
