Adverse Event Classifier (BioBERT) ONNX

Description

This model is a BioBERT-based Adverse Event Text Classifier and it is trained for analyzing the adverse events of drugs mentioned in health documents.

The Text Classifier model has been trained using in-house annotated health-related text that have been labeled with two different classes:

True: Text includes signs or symptoms that are unfavorable, unintended, and/or harmful in a patient who is administered a pharmaceutical product or medical device.

False: The patient did not experience something unfavorable during the course of treatment.

Predicted Entities

True, False

How to use

document_assembler = DocumentAssembler() \
    .setInputCol("text") \
    .setOutputCol("document")

tokenizer = Tokenizer() \
    .setInputCols(["document"]) \
    .setOutputCol("token")

sequence_classifier = MedicalBertForSequenceClassification.pretrained("bert_sequence_classifier_vop_adverse_event_onnx", "en", "clinical/models")\
  .setInputCols(["document", "token"])\
  .setOutputCol("class")

pipeline = Pipeline(stages=[
    document_assembler, 
    tokenizer,
    sequence_classifier    
])

data = spark.createDataFrame([
["I am taking this medication once a day for the last 3 days. I am feeling very bad, pressure on my head, some chest pain, cramps on my neck and feel very weird. I want to reduce my blood pressure naturally. Can I stop this medication? I only took it for 5 days. I was reading here, that a lot of people has been losing weight and exercise and now they have a normal blood pressure. Please let me know, what I can do. The sides effects are horrible"],
["I go the pub about 3-4 times a week and drink quite a bit. I like socialising, been doing so for years now.Recently been getting this occasional pain from the liver area (under right ribs).It comes and goes. Could this be a sign of liver damage?When i get this pain i am usually in the pub drinking.If i press the area under my right rib cage about half way across i can feel pain. Is that pain in the Liver?"]
