put-slot-type

Description

Creates a custom slot type or replaces an existing custom slot type.

To create a custom slot type, specify a name for the slot type and a set of enumeration values, which are the values that a slot of this type can assume. For more information, see how-it-works .

If you specify the name of an existing slot type, the fields in the request replace the existing values in the $LATEST version of the slot type. Amazon Lex removes the fields that you don’t provide in the request. If you don’t specify required fields, Amazon Lex throws an exception. When you update the $LATEST version of a slot type, if a bot uses the $LATEST version of an intent that contains the slot type, the bot’s status field is set to NOT_BUILT .

This operation requires permissions for the lex:PutSlotType action.

Options

--name (string)

The name of the slot type. The name is not case sensitive.

The name can’t match a built-in slot type name, or a built-in slot type name with “AMAZON.” removed. For example, because there is a built-in slot type called AMAZON.DATE , you can’t create a custom slot type called DATE .

For a list of built-in slot types, see Slot Type Reference in the Alexa Skills Kit .

--description (string)

A description of the slot type.

--enumeration-values (list)

A list of EnumerationValue objects that defines the values that the slot type can take. Each value can have a list of synonyms , which are additional values that help train the machine learning model about the values that it resolves for a slot.

When Amazon Lex resolves a slot value, it generates a resolution list that contains up to five possible values for the slot. If you are using a Lambda function, this resolution list is passed to the function. If you are not using a Lambda function you can choose to return the value that the user entered or the first value in the resolution list as the slot value. The valueSelectionStrategy field indicates the option to use.

(structure)

Each slot type can have a set of values. Each enumeration value represents a value the slot type can take.

For example, a pizza ordering bot could have a slot type that specifies the type of crust that the pizza should have. The slot type could include the values

  • thick

  • thin

  • stuffed

value -> (string)

The value of the slot type.

synonyms -> (list)

Additional values related to the slot type value.

(string)

Shorthand Syntax:

value=string,synonyms=string,string ...

JSON Syntax:

[
  {
    "value": "string",
    "synonyms": ["string", ...]
  }
  ...
]

--checksum (string)

Identifies a specific revision of the $LATEST version.

When you create a new slot type, leave the checksum field blank. If you specify a checksum you get a BadRequestException exception.

When you want to update a slot type, set the checksum field to the checksum of the most recent revision of the $LATEST version. If you don’t specify the checksum field, or if the checksum does not match the $LATEST version, you get a PreconditionFailedException exception.

--value-selection-strategy (string)

Determines the slot resolution strategy that Amazon Lex uses to return slot type values. The field can be set to one of the following values:

  • ORIGINAL_VALUE - Returns the value entered by the user, if the user value is similar to the slot value.

  • TOP_RESOLUTION - If there is a resolution list for the slot, return the first value in the resolution list as the slot type value. If there is no resolution list, null is returned.

If you don’t specify the valueSelectionStrategy , the default is ORIGINAL_VALUE .

Possible values:

  • ORIGINAL_VALUE

  • TOP_RESOLUTION

--create-version | --no-create-version (boolean)

When set to true a new numbered version of the slot type is created. This is the same as calling the CreateSlotTypeVersion operation. If you do not specify createVersion , the default is false .

--parent-slot-type-signature (string)

The built-in slot type used as the parent of the slot type. When you define a parent slot type, the new slot type has all of the same configuration as the parent.

Only AMAZON.AlphaNumeric is supported.

--slot-type-configurations (list)

Configuration information that extends the parent built-in slot type. The configuration is added to the settings for the parent slot type.

(structure)

Provides configuration information for a slot type.

regexConfiguration -> (structure)

A regular expression used to validate the value of a slot.

pattern -> (string)

A regular expression used to validate the value of a slot.

Use a standard regular expression. Amazon Lex supports the following characters in the regular expression:

  • A-Z, a-z

  • 0-9

  • Unicode characters (“u<Unicode>”)

Represent Unicode characters with four digits, for example “u0041” or “u005A”.

The following regular expression operators are not supported:

  • Infinite repeaters: *, +, or {x,} with no upper bound.

  • Wild card (.)

Shorthand Syntax:

regexConfiguration={pattern=string} ...

JSON Syntax:

[
  {
    "regexConfiguration": {
      "pattern": "string"
    }
  }
  ...
]

--cli-input-json | --cli-input-yaml (string) Reads arguments from the JSON string provided. The JSON string follows the format provided by --generate-cli-skeleton. If other arguments are provided on the command line, those values will override the JSON-provided values. It is not possible to pass arbitrary binary values using a JSON-provided value as the string will be taken literally. This may not be specified along with --cli-input-yaml.

--generate-cli-skeleton (string) Prints a JSON skeleton to standard output without sending an API request. If provided with no value or the value input, prints a sample input JSON that can be used as an argument for --cli-input-json. Similarly, if provided yaml-input it will print a sample input YAML that can be used with --cli-input-yaml. If provided with the value output, it validates the command inputs and returns a sample output JSON for that command.

--cli-auto-prompt (boolean) Automatically prompt for CLI input parameters.

See ‘aws help’ for descriptions of global parameters.
