## Use
- **Primary Use Case**: This model is designed to extract medical entities such as symptoms, diagnostic tests, and treatments from clinical text in the English 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 in English.
- **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

## 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 = "rigonsallauka/english_medical_ner"
# Load the tokenizer and model
tokenizer = AutoTokenizer.from_pretrained(model_name)
model = AutoModelForTokenClassification.from_pretrained(model_name)
# Sample text for inference
text = "The patient complained of severe headaches and nausea that had persisted for two days. To alleviate the symptoms, he was prescribed paracetamol and advised to rest and drink plenty of fluids."
# Tokenize the input text
inputs = tokenizer(text, return_tensors="pt")
