How to use


document_assembler = DocumentAssembler()
  .setInputCol("text")
  .setOutputCol("document")

sentence_detector = SentenceDetector()
  .setInputCols(["document"])
  .setOutputCol("sentence")

pos = PerceptronModel.pretrained("pos_ud_llct", "la")
  .setInputCols(["document", "token"])
  .setOutputCol("pos")

pipeline = Pipeline(stages=[
  document_assembler,
  sentence_detector,
  posTagger
])

example = spark.createDataFrame(pd.DataFrame({'text': ["Aequaliter Nubila Labs Ioannes de salve ! "]}))

result = pipeline.fit(example).transform(example)



val document_assembler = DocumentAssembler()
        .setInputCol("text")
        .setOutputCol("document")

val sentence_detector = SentenceDetector()
        .setInputCols(["document"])
.setOutputCol("sentence")

val pos = PerceptronModel.pretrained("pos_ud_llct", "la")
        .setInputCols(Array("document", "token"))
        .setOutputCol("pos")

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

val result = pipeline.fit(Seq.empty["Aequaliter Nubila Labs Ioannes de salve ! "].toDS.toDF("text")).transform(data)


import nlu
text = [""Aequaliter Nubila Labs Ioannes de salve ! ""]
token_df = nlu.load('la.pos').predict(text)
token_df
