Person: Individual people (Elon Musk, Marie Curie) Organization: Companies, institutions, groups (Apple, United Nations) Product: Physical or digital products (iPhone, ChatGPT) Place: Locations (Shanghai, Eiffel Tower) Concept: Abstract ideas (machine learning, capitalism) Event: Occurrences (World Cup, IPO)
