Description
ner_dl_bert is a Named Entity Recognition (or NER) model, meaning it annotates text to find features like the names of people, places, and organizations. It was trained on the CoNLL 2003 text corpus. This NER model does not read words directly but instead reads word embeddings, which represent words as points such that more semantically similar words are closer together. ner_dl_bert model is trained with bert_based_cased word embeddings, so be sure to use the same embeddings in the pipeline.
