Algorithm for training Named Entity Recognition Model
This Named Entity recognition annotator allows for a generic model to be trained by utilizing a CRF machine learning algorithm. 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. Optionally the user can provide an entity dictionary file for better accuracy
