32 - Named Entity Linking
Assigning a unique identity from a knowledge base to a named entity.
Named Entity Linking (NEL) is the task of assigning a unique identity from a knowledge base to an entity. For example, the entities ‘Obama’ and ‘The President’ from document X might refer to the same person, but “Obama” from document X and “Obama” from document Y might not refer to the same person.

NEL can be done by training an Entity Linker with spaCy, or use the knowledge base DBpedia and the service dbpedia-spotlight.org.
