Ottoman-NER Latin (`fatihburakkaragoz/ottoman-ner-latin`)

This model performs Named Entity Recognition (NER) on Ottoman Turkish texts transliterated into Latin script. It identifies named entities such as persons (PER), locations (LOC), and organizations (ORG) in historical Ottoman Turkish texts. The model is fine-tuned from dbmdz/bert-base-turkish-cased using a custom CONLL-formatted dataset annotated specifically for Ottoman Latin script.

Part of the Ottoman-NLP Project

While this specific model (ottoman-ner-latin) was developed independently, it builds upon the broader Ottoman-NLP research direction initiated within Boğaziçi University - BUCOLIN Lab under the guidance of Prof. Dr. Şaziye Betül Özateş.

Usage

Transformers pipeline

python

from transformers import AutoTokenizer, AutoModelForTokenClassification, pipeline

model = AutoModelForTokenClassification.from_pretrained("fatihburakkaragoz/ottoman-ner-latin")
tokenizer = AutoTokenizer.from_pretrained("fatihburakkaragoz/ottoman-ner-latin")

ner_pipeline = pipeline("ner", model=model, tokenizer=tokenizer, aggregation_strategy="simple")

text = "Emin Bey’in kuklaları bir haftadır Tepebaşı’nda oynuyor."
entities = ner_pipeline(text)
print(entities)
