public sealed class Entity : IMessage<Entity>, IEquatable<Entity>, IDeepCloneable<Entity>, IBufferMessage, IMessage
Represents a phrase in the text that is a known entity, such as
a person, an organization, or location. The API associates information, such
as salience and mentions, with entities.
For most entity types, the metadata is a Wikipedia URL (wikipedia_url)
and Knowledge Graph MID (mid), if they are available. For the metadata
associated with other entity types, see the Type table below.
The salience score associated with the entity in the [0, 1.0] range.
The salience score for an entity provides information about the
importance or centrality of that entity to the entire document text.
Scores closer to 0 are less salient, while scores closer to 1.0 are highly
