# Info

This is a fine-tuned model on the NER task. The original model is Turku NLP's [bert-base-finnish-uncased-v1](https://huggingface.co/TurkuNLP/bert-base-finnish-uncased-v1), and the fine-tuning dataset is Turku NLP's [turku_ner_corpus](https://huggingface.co/datasets/turku_ner_corpus/). 

The model is released under Apache 2.0.

Please mention the training dataset if you use this model:

## Usage

You can use cURL to access this model:

```
$ curl -X POST -H "Authorization: Bearer YOUR_API_KEY" -H "Content-Type: application/json" -d '{"inputs": "Asun Brysselissä, Euroopan pääkaupungissa."}' https://api-inference.huggingface.co/models/iguanodon-ai/bert-base-finnish-uncased-ner
```

Or Python API:

```
from transformers import AutoModelForTokenClassification, AutoTokenizer

model = AutoModelForTokenClassification.from_pretrained("iguanodon-ai/bert-base-finnish-uncased-ner")
tokenizer = AutoTokenizer.from_pretrained("iguanodon-ai/bert-base-finnish-uncased-ner")

inputs = tokenizer("Asun Brysselissä, Euroopan pääkaupungissa.", return_tensors="pt")
outputs = model(**inputs)
```
