PartitionTransformer

class PartitionTransformer extends AnnotatorModel[PartitionTransformer] with HasSimpleAnnotate[PartitionTransformer] with HasReaderProperties with HasEmailReaderProperties with HasExcelReaderProperties with HasHTMLReaderProperties with HasPowerPointProperties with HasTextReaderProperties with HasPdfProperties with HasXmlReaderProperties with HasChunkerProperties

The PartitionTransformer annotator allows you to use the Partition feature more smoothly within existing Spark NLP workflows, enabling seamless reuse of your pipelines. PartitionTransformer can be used for extracting structured content from various document types using Spark NLP readers. It supports reading from files, URLs, in-memory strings, or byte arrays, and returns parsed output as a structured Spark DataFrame.

Supported formats include plain text, HTML, Word (.doc/.docx), Excel (.xls/.xlsx), PowerPoint (.ppt/.pptx), email files (.eml, .msg), and PDFs.

Example

import com.johnsnowlabs.partition.PartitionTransformer
import com. johnsnowlabs. nlp. base. DocumentAssembler
import org.apache.spark.ml.Pipeline
import spark.implicits._
val urls = Seq("https://www.blizzard.com", "https://www.google.com/").toDS.toDF("text")

val documentAssembler = new DocumentAssembler()
  .setInputCol("text")
  .setOutputCol("documents")

val partition = new PartitionTransformer()
  .setInputCols("document")
  .setOutputCol("partition")
  .setContentType("url")
  .setHeaders(Map("Accept-Language" -> "es-ES"))

val pipeline = new Pipeline()
  .setStages(Array(documentAssembler, partition))

val pipelineModel = pipeline.fit(testDataSet)
val resultDf = pipelineModel.transform(testDataSet)

resultDf.show()
