Resource: EntityType

Entities are extracted from user input and represent parameters that are meaningful to your application. For example, a date range, a proper name such as a geographic location or landmark, and so on. Entities represent actionable data for your application.

When you define an entity, you can also include synonyms that all map to that entity. For example, "soft drink", "soda", "pop", and so on.

There are three types of entities:

  • System - entities that are defined by the Dialogflow API for common data types such as date, time, currency, and so on. A system entity is represented by the EntityType type.

  • Custom - entities that are defined by you that represent actionable data that is meaningful to your application. For example, you could define a pizza.sauce entity for red or white pizza sauce, a pizza.cheese entity for the different types of cheese on a pizza, a pizza.topping entity for different toppings, and so on. A custom entity is represented by the EntityType type.

  • User - entities that are built for an individual user such as favorites, preferences, playlists, and so on. A user entity is represented by the SessionEntityType type.

For more information about entity types, see the Dialogflow documentation.

Fields
name

string

The unique identifier of the entity type. Required for EntityTypes.UpdateEntityType. Format: projects/<ProjectID>/locations/<LocationID>/agents/<AgentID>/entityTypes/<EntityTypeID>.
displayName

string

Required. The human-readable name of the entity type, unique within the agent.
kind

enum (Kind)

Required. Indicates the kind of entity type.
autoExpansionMode

enum (AutoExpansionMode)

Indicates whether the entity type can be automatically expanded.
entities[]

object (Entity)

The collection of entity entries associated with the entity type.
excludedPhrases[]

object (ExcludedPhrase)

Collection of exceptional words and phrases that shouldn't be matched. For example, if you have a size entity type with entry giant(an adjective), you might consider adding giants(a noun) as an exclusion. If the kind of entity type is KIND_MAP, then the phrases specified by entities and excluded phrases should be mutually exclusive.
enableFuzzyExtraction

boolean

Enables fuzzy entity extraction during classification.
redact

boolean

Indicates whether parameters of the entity type should be redacted in log. If redaction is enabled, page parameters and intent parameters referring to the entity type will be replaced by parameter name during logging.

Kind

Represents kinds of entities.

Enums
KIND_UNSPECIFIED Not specified. This value should be never used.
KIND_MAP Map entity types allow mapping of a group of synonyms to a canonical value.
KIND_LIST List entity types contain a set of entries that do not map to canonical values. However, list entity types can contain references to other entity types (with or without aliases).
KIND_REGEXP Regexp entity types allow to specify regular expressions in entries values.

AutoExpansionMode

Represents different entity type expansion modes. Automated expansion allows an agent to recognize values that have not been explicitly listed in the entity (for example, new kinds of shopping list items).

Enums
AUTO_EXPANSION_MODE_UNSPECIFIED Auto expansion disabled for the entity.
AUTO_EXPANSION_MODE_DEFAULT Allows an agent to recognize values that have not been explicitly listed in the entity.

ExcludedPhrase

An excluded entity phrase that should not be matched.

JSON representation

  "value": string
}
Fields
