class LemmatizerModel extends AnnotatorModel[LemmatizerModel] with HasSimpleAnnotate[LemmatizerModel]

Class to find standarized lemmas from words. Uses a user-provided or default dictionary.

Retrieves lemmas out of words with the objective of returning a base dictionary word. Retrieves the significant part of a word

See https://github.com/JohnSnowLabs/spark-nlp/blob/master/src/test/scala/com/johnsnowlabs/nlp/annotators/LemmatizerTestSpec.scala for examples of how to use this API
