Entity Types
TopicOverview »
The Wolfram Language provides access to curated, computable data about millions of entities across hundreds of entity types. Wolfram Language entities represent physical entities as well as mathematical and other scientific concepts, and can be accessed via natural language input or programmatically retrieved and incorporated into complex computations. Custom and dynamic entity types can also be introduced, from external entity stores, relational databases, etc.
