class Reader2Doc extends Transformer with DefaultParamsWritable with HasOutputAnnotatorType with HasOutputAnnotationCol with HasBinaryReaderProperties with HasTextReaderProperties with HasReaderContent

The Reader2Doc annotator allows you to use the reading files more smoothly within existing Spark NLP workflows, enabling seamless reuse of your pipelines. Reader2Doc can be used for extracting structured content from various document types using Spark NLP readers. It supports reading from many files types and returns parsed output as a structured Spark DataFrame.

By default, the annotator combines all extracted elements into a single document annotation. For more fine-grained control, you can use setOutputAsDocument(false) and setExplodeDocs(true) to filter individual elements.

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.reader.Reader2Doc
import com. johnsnowlabs.nlp.base.DocumentAssembler
import org.apache.spark.ml.Pipeline

val reader2Doc = new Reader2Doc()
  .setContentType("application/pdf")
  .setContentPath(s"$pdfDirectory/")
  .setExplodeDocs(true)

val pipeline = new Pipeline()
  .setStages(Array(reader2Doc))

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

resultDf.show()
