2020/02/06 - Amazon Lex Model Building Service - 3 updated api methods
Changes Amazon Lex now supports AMAZON.AlphaNumeric with regular expressions.
{'parentSlotTypeSignature': 'string',
'slotTypeConfigurations': [{'regexConfiguration': {'pattern': 'string'}}]}
Creates a new version of a slot type based on the $LATEST version of the specified slot type. If the $LATEST version of this resource has not changed since the last version that you created, Amazon Lex doesn't create a new version. It returns the last version that you created.
Note
You can update only the $LATEST version of a slot type. You can't update the numbered versions that you create with the CreateSlotTypeVersion operation.
When you create a version of a slot type, Amazon Lex sets the version to 1. Subsequent versions increment by 1. For more information, see versioning-intro .
This operation requires permissions for the lex:CreateSlotTypeVersion action.

Request Syntax
client.create_slot_type_version(
name='string',
checksum='string'
)
string
[REQUIRED]
The name of the slot type that you want to create a new version for. The name is case sensitive.
string
Checksum for the $LATEST version of the slot type that you want to publish. If you specify a checksum and the $LATEST version of the slot type has a different checksum, Amazon Lex returns a PreconditionFailedException exception and doesn't publish the new version. If you don't specify a checksum, Amazon Lex publishes the $LATEST version.

Returns information about a specific version of a slot type. In addition to specifying the slot type name, you must specify the slot type version.
This operation requires permissions for the lex:GetSlotType action.

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.

string
[REQUIRED]
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 .
string
A description of the slot type.
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.

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