Description
This model is trained with the Logistic Regression algorithm and classifies text/sentence into two categories:
True : The sentence is talking about a possible ADE
False : The sentence doesn’t have any information about an ADE.
The corpus used for model training is ADE-Corpus-V2 Dataset: Adverse Drug Reaction Data. This is a dataset for classification of a sentence if it is ADE-related (True) or not (False).
Predicted Entities
True, False
How to use
document_assembler = DocumentAssembler()\
.setInputCol("text")\
.setOutputCol("document")
tokenizer = Tokenizer()\
.setInputCols("document")\
.setOutputCol("token")
logreg = DocumentLogRegClassifierModel.pretrained("classifier_logreg_ade", "en", "clinical/models")\
.setInputCols("token")\
.setOutputCol("prediction")
clf_Pipeline = Pipeline(stages=[
document_assembler,
tokenizer,
logreg])
data = spark.createDataFrame([["""None of the patients required treatment for the overdose."""], ["""Detection of activated eosinophils in nasal polyps of an aspirin-induced asthma patient."""]]).toDF("text")
result = clf_Pipeline.fit(data).transform(data)
val document_assembler =new DocumentAssembler()
.setInputCol("text")
.setOutputCol("document")
val tokenizer = new Tokenizer()
.setInputCols("document")
.setOutputCol("token")
val logreg = new DocumentLogRegClassifierModel.pretrained("classifier_logreg_ade", "en", "clinical/models")
.setInputCols("token")
.setOutputCol("prediction")
val clf_Pipeline = new Pipeline().setStages(Array(document_assembler, tokenizer, logreg))
val data = Seq(Array("None of the patients required treatment for the overdose.", "Detection of activated eosinophils in nasal polyps of an aspirin-induced asthma patient.")).toDS().toDF("text")
val result = clf_Pipeline.fit(data).transform(data)
