Knowledge Representation & Access

Deeply integrated into the Wolfram Language is access to the immense and continuously updated Wolfram Knowledgebase also used in Wolfram|Alpha. Free-form linguistics makes it easy to identify many millions of entities and many thousands of properties and automatically generate precise Wolfram Language representations suitable for extensive further computation.


(Ctrl+) give free-form linguistics to be converted to Wolfram Language form

Entity symbolic representation of a named entity of any type (e.g. "City", "Person", ...):

EntityProperty symbolic representation of a property for a type of entity (e.g. "Population"):

EntityValue value of a specific property of an entity (e.g. density of gold)

EntityClass representation of a class of entities of a given type (e.g. G8 countries):

EntityPropertyClass a class of properties of a given type (e.g. demographics)

CommonName common printable name of an entity or property

CanonicalName unique canonical name of an entity or property

EntityTypeName name of the type of an entity

EntityList a list of entities of a given type or class
