class NerDLModel extends AnnotatorModel[NerDLModel] with HasBatchedAnnotate[NerDLModel] with WriteTensorflowModel with HasStorageRef with ParamsAndFeaturesWritable with HasEngine

This Named Entity recognition annotator is a generic NER model based on Neural Networks.

Neural Network architecture is Char CNNs - BiLSTM - CRF that achieves state-of-the-art in most datasets.

This is the instantiated model of the NerDLApproach. For training your own model, please see the documentation of that class.

Pretrained models can be loaded with pretrained of the companion object:

val nerModel = NerDLModel.pretrained()
  .setInputCols("sentence", "token", "embeddings")
  .setOutputCol("ner")

The default model is "ner_dl", if no name is provided.

For available pretrained models please see the Models Hub. Additionally, pretrained pipelines are available for this module, see Pipelines.

Note that some pretrained models require specific types of embeddings, depending on which they were trained on. For example, the default model "ner_dl" requires the WordEmbeddings "glove_100d".

For extended examples of usage, see the Examples and the NerDLSpec.

Example

import spark.implicits._
import com.johnsnowlabs.nlp.base.DocumentAssembler
import com.johnsnowlabs.nlp.annotators.Tokenizer
import com.johnsnowlabs.nlp.annotators.sbd.pragmatic.SentenceDetector
import com.johnsnowlabs.nlp.embeddings.WordEmbeddingsModel
import com.johnsnowlabs.nlp.annotators.ner.dl.NerDLModel
import org.apache.spark.ml.Pipeline

// First extract the prerequisites for the NerDLModel
val documentAssembler = new DocumentAssembler()
  .setInputCol("text")
  .setOutputCol("document")

val sentence = new SentenceDetector()
  .setInputCols("document")
  .setOutputCol("sentence")

val tokenizer = new Tokenizer()
  .setInputCols("sentence")
  .setOutputCol("token")

val embeddings = WordEmbeddingsModel.pretrained()
  .setInputCols("sentence", "token")
  .setOutputCol("bert")

// Then NER can be extracted
val nerTagger = NerDLModel.pretrained()
  .setInputCols("sentence", "token", "bert")
  .setOutputCol("ner")

val pipeline = new Pipeline().setStages(Array(
  documentAssembler,
  sentence,
  tokenizer,
  embeddings,
  nerTagger
))

val data = Seq("U.N. official Ekeus heads for Baghdad.").toDF("text")
val result = pipeline.fit(data).transform(data)

result.select("ner.result").show(false)
