🌐 KAIdol NER Multilingual Model

This is a multilingual NER (Named Entity Recognition) model developed as part of the KAIdol Project.
It is based on Davlan/xlm-roberta-base-ner-hrl, fine-tuned on the WikiAnn dataset for Korean (ko), English (en), Spanish (es), and Portuguese (pt).

🧠 Model Details

• Base model: Davlan/xlm-roberta-base-ner-hrl
• NER Tags:
  • PER: Person
  • ORG: Organization
  • LOC: Location
• Tokenizer: AutoTokenizer from base model
• Max length: 128 tokens

📊 Training Configuration

Parameter	Value
Epochs	5
Batch Size	16
Optimizer	AdamW
Learning Rate	5e-5
Loss	CrossEntropy with class weights
Dataset	WikiAnn (en, ko, es, pt)

✅ Performance Summary

Language	F1-macro	PER F1	ORG F1	LOC F1
English	0.74	0.84	0.63	0.76
Korean	0.43	0.46	0.30	0.52
Spanish	TBD	TBD	TBD	TBD
Portuguese	TBD	TBD	TBD	TBD

Performance on es and pt will be updated after evaluation. Korean performance is limited due to tokenization issues in WikiAnn.

🚀 Usage Example

from transformers import AutoTokenizer, AutoModelForTokenClassification

model = AutoModelForTokenClassification.from_pretrained("developer-lunark/kaidol-ner-multilingual")
tokenizer = AutoTokenizer.from_pretrained("developer-lunark/kaidol-ner-multilingual")

tokens = tokenizer("Barack Obama nació en Hawái.", return_tensors="pt")
output = model(**tokens)
