Description
Pretrained Question Answering model, adapted from Hugging Face and curated to provide scalability and production-readiness using Spark NLP. cs224n-squad2.0-albert-large-v2 is a English model originally trained by elgeish.
How to use
documentAssembler = MultiDocumentAssembler() \
.setInputCols(["question", "context"]) \
.setOutputCols(["document_question", "document_context"])
spanClassifier = AlbertForQuestionAnswering.pretrained("albert_qa_cs224n_squad2.0_large_v2","en") \
.setInputCols(["document_question", "document_context"]) \
.setOutputCol("answer")\
.setCaseSensitive(True)
pipeline = Pipeline(stages=[documentAssembler, spanClassifier])
data = spark.createDataFrame([["What is my name?", "My name is Clara and I live in Berkeley."]]).toDF("question", "context")
result = pipeline.fit(data).transform(data)
val documentAssembler = new MultiDocumentAssembler()
.setInputCols(Array("question", "context"))
.setOutputCols(Array("document_question", "document_context"))
val spanClassifer = AlbertForQuestionAnswering.pretrained("albert_qa_cs224n_squad2.0_large_v2","en")
.setInputCols(Array("document", "token"))
.setOutputCol("answer")
.setCaseSensitive(true)
val pipeline = new Pipeline().setStages(Array(documentAssembler, spanClassifier))
val data = Seq("What is my name?", "My name is Clara and I live in Berkeley.").toDF("question", "context")
val result = pipeline.fit(data).transform(data)
import nlu
nlu.load("en.answer_question.squadv2.albert.large_v2").predict("""What is my name?|||"My name is Clara and I live in Berkeley.""")
