class NerDLApproach extends AnnotatorApproach[NerDLModel] with NerApproach[NerDLApproach] with Logging with ParamsAndFeaturesWritable

This Named Entity recognition annotator allows to train generic NER model based on Neural Networks. Its train data (train_ner) is either a labeled or an external CoNLL 2003 IOB based spark dataset with Annotations columns. Also the user has to provide word embeddings annotation column. Neural Network architecture is Char CNNs - BiLSTM - CRF that achieves state-of-the-art in most datasets.

See https://github.com/JohnSnowLabs/spark-nlp/tree/master/src/test/scala/com/johnsnowlabs/nlp/annotators/ner/dl for further reference on how to use this API.
