How to use

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

chunkerMapper = ChunkMapperModel.pretrained("drug_brandname_ndc_mapper", "en", "clinical/models")\
.setInputCols(["chunk"])\
.setOutputCol("ndc")\
.setRel("Strength_NDC") 

pipeline = Pipeline().setStages([document_assembler,
chunkerMapper])  

model = pipeline.fit(spark.createDataFrame([['']]).toDF('text')) 

lp = LightPipeline(model)

result = lp.fullAnnotate(["zytiga", "zyvana", "ZYVOX", "ZYTIGA"])

val document_assembler = new DocumentAssembler()
.setInputCol("text")
.setOutputCol("chunk")

val chunkerMapper = ChunkMapperModel.pretrained("drug_brandname_ndc_mapper", "en", "clinical/models")
.setInputCols("chunk")
.setOutputCol("ndc")
.setRel("Strength_NDC") 

val pipeline = new Pipeline().setStages(Array(document_assembler,
				              chunkerMapper))

val text_data = Seq("zytiga", "zyvana", "ZYVOX", "ZYTIGA").toDS.toDF("text")

val res = pipeline.fit(text_data).transform(text_data)

nlu.load("en.map_entity.drug_brand_to_ndc").predict("""Put your text here.""")
