Description
This Greek Lemmatizer is an scalable, production-ready version of the Rule-based Lemmatizer available in Spacy Lookups Data repository.
How to use
documentAssembler = DocumentAssembler() \
.setInputCol("text") \
.setOutputCol("document")
tokenizer = Tokenizer() \
.setInputCols(["document"]) \
.setOutputCol("token")
lemmatizer = LemmatizerModel.pretrained("lemma_spacylookup","grc") \
.setInputCols(["token"]) \
.setOutputCol("lemma")
pipeline = Pipeline(stages=[documentAssembler, tokenizer, lemmatizer])
example = spark.createDataFrame([["Δεν είσαι καλύτερος από μένα."]], ["text"])
results = pipeline.fit(example).transform(example)
val documentAssembler = new DocumentAssembler()
.setInputCol("text")
.setOutputCol("document")
val tokenizer = new Tokenizer()
.setInputCols(Array("document"))
.setOutputCol("token")
val lemmatizer = LemmatizerModel.pretrained("lemma_spacylookup","grc")
.setInputCols(Array("token"))
.setOutputCol("lemma")
val pipeline = new Pipeline().setStages(Array(documentAssembler, tokenizer, lemmatizer))
val data = Seq("Δεν είσαι καλύτερος από μένα.").toDF("text")
val results = pipeline.fit(data).transform(data)
import nlu
nlu.load("grc.lemma.spacylookup").predict("""Δεν είσαι καλύτερος από μένα.""")
