## Use
- **Primary Use Case**: This model is designed to extract medical entities such as symptoms, diagnostic tests, and treatments from clinical text in the Polish language.
- **Applications**: Suitable for healthcare professionals, clinical data analysis, and research into medical text processing.
- **Supported Entity Types**:
  - `
PROBLEM`: Diseases, symptoms, and medical conditions.
  - `TEST`: Diagnostic procedures and laboratory tests.
  - `TREATMENT`: Medications, therapies, and other medical interventions.

## Training Data
- **Data Sources**: Annotated datasets, including clinical data and translations of English medical text into Polish.
- **Data Augmentation**: The training dataset underwent data augmentation techniques to improve the model's ability to generalize to different text structures.
- **Dataset Split**:
  - **Training Set**: 80%
  -
 **Validation Set**: 10%
  - **Test Set**: 10%

## Model Training
- **Training Configuration**:

## 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:

```python
from transformers import AutoTokenizer, AutoModelForTokenClassification

model_name = "HUMADEX/polish_medical_ner"

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

# Sample text for inference
text = "Pacjent skarżył się na silne bóle głowy i nudności, które utrzymywały się przez dwa dni. W celu złagodzenia objawów przepisano mu paracetamol oraz zalecono odpoczynek i picie dużej ilości płynów."

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