1.  class AnnotationMerger extends AnnotatorModel[AnnotationMerger] with CheckLicense with HasMultipleInputAnnotationCols with HasSimpleAnnotate[AnnotationMerger]

   Merges Annotations from multiple columns.

   Merges Annotations from multiple columns.

   Example

   val empty_data = Seq([[""]]).toDF("text")
   val document1 = DocumentAssembler().setInputCol("text").setOutputCol("document1")
   val document2 = DocumentAssembler().setInputCol("text").setOutputCol("document2")
   val annotation_merger = AnnotationMerger()
       .setInputCols("document1", "document2")
       .setInputType("document")
       .setOutputCol("all_docs")
   
   val pipelineModel = new Pipeline().setStages(Array(
       document1, document2, annotation_merger)).fit(empty_data)
   val lp = LightPipeline(pipelineModel)
   lp.fullAnnotate("one doc to be replicated")
   [{'document1': [Annotation(document, 0, 23, one doc to be replicated, {})], 'document2': [Annotation(document, 0, 23, one doc to be replicated, {})], 'all_docs': [Annotation(document, 0, 23, one doc to be replicated, {}), Annotation(document, 0, 23, one doc to be replicated, {})]}]

2.  class Doc2ChunkInternal extends Model[Doc2ChunkInternal] with RawAnnotator[Doc2ChunkInternal]
3.  class FeaturesAssembler extends AnnotatorModel[FeaturesAssembler] with HasStorageRef with HasSimpleAnnotate[FeaturesAssembler] with CheckLicense

   The FeaturesAssembler is used to collect features from different columns.

   The FeaturesAssembler is used to collect features from different columns. It can collect features from single value columns (anything which can be cast to a float, if casts fails then the value is set to 0), array columns or SparkNLP annotations (if the annotation is an embedding, it takes the embedding, otherwise tries to cast the result field). The output of the transformer is a FEATURE_VECTOR annotation (the numeric vector is in the embeddings field).

4.  class Router extends AnnotatorModel[Router] with HasSimpleAnnotate[Router] with ParamsAndFeaturesWritable with CheckLicense

   This class allows to filter any annotation based on the medatata fields.

   This class allows to filter any annotation based on the medatata fields.
