How to Use

You can easily use this model with the Hugging Face transformers library. Here's an example of how to load and use the model for inference:

from transformers import AutoTokenizer, AutoModelForTokenClassification

model_name = "rigonsallauka/italian_medical_ner"

# Load the tokenizer and model
tokenizer = AutoTokenizer.from_pretrained(model_name)
model = AutoModelForTokenClassification.from_pretrained(model_name)

# Sample text for inference
text = "Il paziente ha lamentato forti mal di testa e nausea che persistevano da due giorni. Per alleviare i sintomi, gli è stato prescritto il paracetamolo e gli è stato consigliato di riposare e bere molti liquidi."

# Tokenize the input text
inputs = tokenizer(text, return_tensors="pt")
