It has been shown that one can significantly increase the semantic information carried by a NER system when we successfully linking entities from a deep learning method to the related entities from a knowledge base BIBREF26 , BIBREF27 . Redirection: For the Wikidata linking element, we recognize that the lookup will be constrained by the most common lookup name for each entity.  
 Question: How do they combine a deep learning model with a knowledge base?
Entities from a deep learning model are linked to the related entities from a knowledge base by a lookup.
