 ## Intended use
 The model is finetuned for negation detection 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. This particular model is trained on a 32-max token windows surrounding the concept-to-be negated.
 
+## Minimal example
+
+```python
+tokenizer = AutoTokenizer\
+ .from_pretrained("UMCU/MedRoBERTa.nl_NegationDetection")
+model = AutoModelForTokenClassification\
+ .from_pretrained("UMCU/MedRoBERTa.nl_NegationDetection")
+
+some_text = "De patient was niet aanspreekbaar en hij zag er grauw uit. \
+Hij heeft de inspanningstest echter goed doorstaan." 
+inputs = tokenizer(some_text, return_tensors='pt')
+output = model.forward(inputs)
+probas = torch.nn.functional.softmax(output.logits[0]).detach().numpy()
+
+# koppel aan tokens
+input_tokens = tokenizer.convert_ids_to_tokens(inputs['input_ids'][0])
+target_map = {0: 'B-Negated', 1:'B-NotNegated',2:'I-Negated',3:'I-NotNegated'}
+results = [{'token': input_tokens[idx],
+ 'proba_negated': proba_arr[0]+proba_arr[2],
+ 'proba_not_negated': proba_arr[1]+proba_arr[3]
+ } 
+ for idx,proba_arr in enumerate(probas)]
+

 ## Data
 The pre-trained model was trained the Dutch section of OSCAR (about 39GB), and is described here: http://dx.doi.org/10.18653/v1/2020.findings-emnlp.292.
