GraphFinisher

class GraphFinisher extends Transformer

Helper class to convert the knowledge graph from GraphExtraction into a generic format, such as RDF.

Example

This is a continuation of the example of GraphExtraction. To see how the graph is extracted, see the documentation of that class.

import com.johnsnowlabs.nlp.GraphFinisher

val graphFinisher = new GraphFinisher()
  .setInputCol("graph")
  .setOutputCol("graph_finished")
  .setOutputAsArray(false)

val finishedResult = graphFinisher.transform(result)
finishedResult.select("text", "graph_finished").show(false)
+-----------------------------------------------------+-----------------------------------------------------------------------+
|text                                                 |graph_finished                                                         |
