How to use
document_assembler = DocumentAssembler().setInputCol("text").setOutputCol("document")
tokenizer = Tokenizer().setInputCols(['document']).setOutputCol('token')
embeddings = BertEmbeddings.pretrained('biobert_pubmed_base_cased')\
.setInputCols(["document", 'token'])\
.setOutputCol("word_embeddings")
sentence_embeddings = SentenceEmbeddings() \
.setInputCols(["document", "word_embeddings"]) \
.setOutputCol("sentence_embeddings") \
.setPoolingStrategy("AVERAGE")
classifier = ClassifierDLModel.pretrained('classifierdl_ade_conversational_biobert', 'en', 'clinical/models')\
.setInputCols(['document', 'token', 'sentence_embeddings']).setOutputCol('class')
nlp_pipeline = Pipeline(stages=[document_assembler, tokenizer, embeddings, sentence_embeddings, classifier])
light_pipeline = LightPipeline(nlp_pipeline.fit(spark.createDataFrame([['']]).toDF("text")))
annotations = light_pipeline.fullAnnotate(["I feel a bit drowsy & have a little blurred vision after taking an insulin", "I feel great after taking tylenol"])
import nlu
nlu.load("en.classify.ade.conversational").predict("""I feel a bit drowsy & have a little blurred vision after taking an insulin""")
