This page provides a reference for all system entities provided by Dialogflow.
System entity support differs for each language. To check which system entities support a specific language, filter the example table by language. If a system entity has no example for that language, then it is not supported, even though that entity can be selected for that language in the console. You can still use that entity in that language to match extended system entities if the entity is extendable.
The table below describes all system entities. You can filter the table by system entity category, system entity name, and/or extendibility. See the next section for examples of these system entities in supported languages.
The table below provides input and output examples for all system entities. You can filter the table by language and/or system entity name. If an entity has no examples for a specific language, the entity does not support that language. See the limitations section for details.
The table below provides supported units for system entities. You can filter the table by language and/or measured quantity.
