[Related Interpreter](https://reference.wolfram.com/language/ref/interpreter/Building.en.md) Entity["Building", name] or Entity[...] represents an entity of type "Building". Entity[...][prop] gives the value of a specified property. Entity[...][{propi, …}] gives the value of a list of properties. EntityClass["Building", {propi -> speci, …}] represents a class of entities with values of propi defined by speci. ## Sample Entities * Entity["Building", "BurjKhalifa::45f7b"]Entity["Building", "DetKongeligeSlott::wsy8x"]Entity["Building", "NeuschwansteinCastle::jtbs5"]Entity["Building", "LeVequeTower::s67m6"]Entity["Building", "TwoWorldTradeCenter::s3653"]Entity["Building", "CNTower::b5s3m"]Entity["Building", "PetronasTower1::245r5"]Entity["Building", "ShanghaiWorldFinancialCenter::87d37"]Entity["Building", "PonteCityApartments::s6fxx"]Entity["Building", "CommerzbankTower::4tbnr"]**…** ## Sample Entity Classes * EntityClass["Building", "AzrieliCenter"]EntityClass["Building", "CityPlexTowers"]EntityClass["Building", "CTBAComplex"]EntityClass["Building", "GlynnAcademyBuildings"]EntityClass["Building", "ImperialTowers"]EntityClass["Building", "PyramidsDashur"]EntityClass["Building", "PyramidsSenusret"]EntityClass["Building", "Rondo1"]EntityClass["Building", "SkyscrapersDestroyed"]EntityClass["Building", "USBankPlazaTowersMN"]**…** ## Properties | | | | ---------------------- | ----------------------- | | AdministrativeDivision | administrative region | | Architect | architect | | ArchitecturalHeight | architectural height | | ArchitecturalStyle | style | | ArchitectureFirm | firm | | Cities | city location | | Clients | clients | | ConstructionCost | construction cost | | ConstructionEndDate | completion date | | ConstructionStartDate | construction start date | | ConstructionStatus | construction status | | Coordinates | coordinates | | Countries | country | | DestructionDate | destruction date | | Elevation | elevation | | ElevatorCount | number of elevators | | Engineers | engineers | | EntityClasses | entity classes | | EntityTypeList | entity type list | | FloorCount | floors | | FloorSpace | floor area | | GroundBreakingDate | ground breaking date | | Height | total height | | Image | image | | Latitude | latitude | | Longitude | longitude | | Material | material | | Name | name | | OpeningDate | opening date | | Position | position | | RenovationDate | renovation date | | RoofHeight | roof height | | RoomCount | number of rooms | | SeatingCapacity | seating capacity | | StructuralEngineer | structural engineer | | StructuralSystem | structural system | ## Details * ``"Building"`` entities include skyscrapers, residential, retail and office buildings, as well as various other manmade structures such as pyramids, temples and communication towers. * ``"Building"`` entity classes include notable multi-building complexes as well as some assorted categories of buildings, e.g. ``"SkyscrapersDestroyed"``. * Some properties are available for the [`"Building"`](https://reference.wolfram.com/language/ref/entity/Building.en.md) entity type as a whole and can be given using the form ``EntityValue["Building", property]``. Such properties include: | | | | ----------------------------- | ------------------------------------------------------------------ | | "Properties" | the list of available properties | | "PropertyCanonicalNames" | the standard names of available properties | | "SampleEntities" | a sample list of available entities (typically of length 10) | | "SampleEntityClasses" | a sample list of available entity classes (typically of length 10) | | "EntityCount" | number of entities available | | "Entities" | the list of available entities | | "EntityCanonicalNames" | the standard names of available entities | | "EntityClasses" | the list of available entity classes | | "EntityClassCanonicalNames" | the standard names of available entity classes | | "PropertyClasses" | the list of available property classes | | "PropertyClassCanonicalNames" | the standard names of available property classes | | "PropertyCount" | number of properties available | * The following annotations can be used in the third argument of ``EntityValue["Building", property, annotation]`` : | | | | --- | --- | | "Source" | source information for the property | | "Date" | the date associated with the entity-property value (if any) | | "EntityAssociation" | an association of entities and entity-property values | | "PropertyAssociation" | an association of properties and entity-property values | | "EntityPropertyAssociation" | an association in which the specified entities are keys, and values are a nested association of properties and entity-property values | | "PropertyEntityAssociation" | an association in which the specified properties are keys, and values are a nested association of entities and entity-property values | | "Dataset" | a dataset in which the specified entities are keys, and values are an association of property names and entity-property values | * The following annotations can be used in the second argument of ``EntityValue[property, annotation]`` : | | | | ------------------------ | --------------------------------------------------------------- | | "Qualifiers" | the list of possible qualifiers for the property | | "QualifierValues" | the list of possible values that can be given to each qualifier | | "DefaultQualifierValues" | the list of default values for the property's qualifiers | | "Description" | a brief textual description of the property | | "Definition" | a detailed textual definition of the property | | "PhysicalQuantity" | the physical quantity associated with the entity-property value | | "Unit" | the unit associated with the entity-property value | * A qualifier value of ``Automatic`` indicates that an applicable format of values can be used, e.g. for the ``"Date"`` qualifier; this includes a proper date or date span. --- ## Examples (11) ### Basic Examples (4) Use ctrl+= for entity discovery: ```wl In[1]:= \[FreeformPrompt]["burj dubai"] Out[1]= Entity["Building", "BurjKhalifa::45f7b"] ``` --- Use ctrl+= to discover properties of a building: ```wl In[1]:= \[FreeformPrompt]["how tall is the chrysler building"] Out[1]= Quantity[1046.5879265091864, "Feet"] ``` --- Retrieve all available properties of a building: ```wl In[1]:= \[FreeformPrompt]["burj khalifa"]["Dataset"] Out[1]= Dataset[Association[EntityProperty["Building", "AdministrativeDivision"] -> {Entity["AdministrativeDivision", {"Dubai", "UnitedArabEmirates"}]}, EntityProperty["Building", "Architect"] -> {Entity["Person", "AdrianSmith::cqg2q"], Entity[ ... asses"] -> {EntityClass["Building", "Skyscraper"], EntityClass["Building", {"ConstructionStatus", "Completed"}]}, EntityProperty["Thing", "EntityTypeList"] -> {EntityType["Building"]}, EntityProperty["Thing", "Name"] -> "Burj Khalifa"]] ``` --- Find the 10 tallest completed buildings: ```wl In[1]:= EntityClass["Building", {"ConstructionStatus" -> "Completed", "Height" -> TakeLargest[10]}]//EntityList Out[1]= {Entity["Building", "BurjKhalifa::45f7b"], Entity["Building", "KL118::49q94"], Entity["Building", "TokyoSkyTree::tkr2g"], Entity["Building", "ShanghaiTower::kfm6t"], Entity["Building", "CantonTower::6mwph"], Entity["Building", "MakkahClockRoyalTower::pc2pc"], Entity["Building", "PingAnFinanceCenter::y5454"], Entity["Building", "LotteWorldTower::w7762"], Entity["Building", "CNTower::b5s3m"], Entity["Building", "OneWorldTradeCenter::v6pj6"]} ``` ### Scope (5) Get architectural information about a building: ```wl In[1]:= \[FreeformPrompt]["empire state building"][{"Architect", "ArchitecturalStyle", "ArchitectureFirm"}, "PropertyAssociation"] Out[1]= <|"Architect" -> {Entity["Person", "WilliamFLamb::3rf3y"]}, "ArchitecturalStyle" -> {"Art Deco", "Streamline Moderne"}, "ArchitectureFirm" -> {"Shreve, Lamb & Harmon"}|> ``` --- Get dimensional properties of a building: ```wl In[1]:= \[FreeformPrompt]["burj khalifa"][{"FloorCount", "FloorSpace", "Height"}] Out[1]= {163, Quantity[3.3311396483904076740145683`3.*^6, "Feet"^2], Quantity[2716.535433070866, "Feet"]} ``` --- Retrieve heights for a group of buildings: ```wl In[1]:= \[FreeformPrompt]["pyramids of giza"]["Height", "EntityAssociation"]//Sort Out[1]= <|Entity["Building", "KhentkausI::szj39"] -> Quantity[57.414698162729664, "Feet"], Entity["Building", "TheGreatSphinxOfGiza::3647c"] -> Quantity[65.61679790026247, "Feet"], Entity["Building", "PyramidG1C::hj9k4"] -> Quantity[97.11286089238845, "Fee ...
