How to use
document_assembler = DocumentAssembler()
.setInputCol("text")
.setOutputCol("document")
sentence_detector = SentenceDetector()
.setInputCols(["document"])
.setOutputCol("sentence")
pos = PerceptronModel.pretrained("pos_ud_tdt", "fi")
.setInputCols(["document", "token"])
.setOutputCol("pos")
pipeline = Pipeline(stages=[
document_assembler,
sentence_detector,
posTagger
])
example = spark.createDataFrame(pd.DataFrame({'text': ["Hei John Snow Labs! "]}))
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_tdt", "fi")
.setInputCols(Array("document", "token"))
.setOutputCol("pos")
val pipeline = new Pipeline().setStages(Array(document_assembler, sentence_detector, pos))
val result = pipeline.fit(Seq.empty["Hei John Snow Labs! "].toDS.toDF("text")).transform(data)
