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.
