# Description
This model is a spaCy SpanCategorizer model trained from scratch on Dutch echocardiogram reports sourced from Electronic Health Records. The publication associated with the span classification task can be found at https://arxiv.org/abs/2408.06930. The config file for training the model can be found at https://github.com/umcu/echolabeler.

# Minimum working example
```python
!pip install https://huggingface.co/baukearends/Echocardiogram-SpanCategorizer-lv-dil/resolve/main/nl_Echocardiogram_SpanCategorizer_lv_dil-any-py3-none-any.whl
```
```python
import spacy
nlp = spacy.load("nl_Echocardiogram_SpanCategorizer_lv_dil")
```
```python
prediction = nlp("Op dit echo geen duidelijke WMA te zien, goede systolische L.V. functie, normale dimensies LV, wel L.V.H., diastolische dysfunctie graad 1A tot 2. Geringe aortastenose en - matige -insufficientie. Geringe M.I.")
for span, score in zip(prediction.spans['sc'], prediction.spans['sc'].attrs['scores']):
    print(f"Span: {span}, label: {span.label_}, score: {score[0]:.3f}")
```

# Intended use
The model is developed for span classification on Dutch clinical text. Since it is a domain-specific model trained on medical data, it is meant to be used on medical NLP tasks for Dutch.

# Data
The model was trained on approximately 4,000 manually annotated echocardiogram reports from the University Medical Centre Utrecht. The training data was anonymized before starting the training procedure.
