How to use


pos = PerceptronModel.pretrained("pos_ud_alpino", "nl") \
    .setInputCols(["document", "token"]) \
    .setOutputCol("pos")
nlp_pipeline = Pipeline(stages=[document_assembler, sentence_detector, tokenizer, pos])
light_pipeline = LightPipeline(nlp_pipeline.fit(spark.createDataFrame([['']]).toDF("text")))
results = light_pipeline.fullAnnotate("Behalve dat hij de koning van het noorden is, is John Snow een Engelse arts en een leider in de ontwikkeling van anesthesie en medische hygiëne.")

val pos = PerceptronModel.pretrained("pos_ud_alpino", "nl")
    .setInputCols(Array("document", "token"))
    .setOutputCol("pos")
