How to use

pos = PerceptronModel.pretrained("pos_ud_bokmaal", "nb") \
    .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("Annet enn å være kongen i nord, er John Snow en engelsk lege og en leder innen utvikling av anestesi og medisinsk hygiene.")

val pos = PerceptronModel.pretrained("pos_ud_bokmaal", "nb")
    .setInputCols(Array("document", "token"))
    .setOutputCol("pos")

val pipeline = new Pipeline().setStages(Array(document_assembler, sentence_detector, tokenizer, pos))
val data = Seq("Annet enn å være kongen i nord, er John Snow en engelsk lege og en leder innen utvikling av anestesi og medisinsk hygiene.").toDF("text")
val result = pipeline.fit(data).transform(data)

import nlu
