Description
Pretrained BertForZeroShotClassification model, adapted from Hugging Face and curated to provide scalability and production-readiness using Spark NLP.gbert_large_zeroshot_nli is a German model originally trained by svalabs.
How to use
documentAssembler = DocumentAssembler() \
.setInputCol('text') \
.setOutputCol('document')
tokenizer = Tokenizer() \
.setInputCols(['document']) \
.setOutputCol('token')
zeroShotClassifier = BertForZeroShotClassification.pretrained("gbert_large_zeroshot_nli","de") \
.setInputCols(["document","token"]) \
.setOutputCol("class")
pipeline = Pipeline().setStages([documentAssembler, tokenizer, zeroShotClassifier])
data = spark.createDataFrame([["I love spark-nlp"]]).toDF("text")
pipelineModel = pipeline.fit(data)
pipelineDF = pipelineModel.transform(data)
val documentAssembler = new DocumentAssembler()
.setInputCols("text")
.setOutputCols("document")
val tokenizer = new Tokenizer()
.setInputCols("document")
.setOutputCol("token")
val zeroShotClassifier = BertForZeroShotClassification.pretrained("gbert_large_zeroshot_nli", "de")
.setInputCols(Array("documents","token"))
.setOutputCol("class")
val pipeline = new Pipeline().setStages(Array(documentAssembler, tokenizer, zeroShotClassifier))
val data = Seq("I love spark-nlp").toDS.toDF("text")
val pipelineModel = pipeline.fit(data)
val pipelineDF = pipelineModel.transform(data)
