eval F1-Score: **83,78** 

test F1-Score: **83,76** 

## Model Usage

```python

from transformers import AutoTokenizer, AutoModelForTokenClassification

from transformers import pipeline

tokenizer = AutoTokenizer.from_pretrained("philschmid/distilroberta-base-ner-wikiann")

model = AutoModelForTokenClassification.from_pretrained("philschmid/distilroberta-base-ner-wikiann")

nlp = pipeline("ner", model=model, tokenizer=tokenizer, grouped_entities=True)

example = "Jag heter Per och jag jobbar på KTH"

nlp(example)
