Reference documentation and code samples for the Cloud Natural Language v2 API class Entity.
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 probability 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.
For calls to [AnalyzeEntitySentiment][] or if
[AnnotateTextRequest.Features.extract_entity_sentiment][google.cloud.language.v2.AnnotateTextRequest.Features.extract_entity_sentiment]
is set to true, this field will contain the aggregate sentiment expressed
for this entity in the provided document.
