AWS services or capabilities described in AWS Documentation may vary by region/location. Click Getting Started with Amazon AWS to see specific differences applicable to the China (Beijing) Region.

Container for the parameters to the PutSlotType operation. 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.

This operation requires permissions for the lex:PutSlotType action.

Properties

NameTypeDescription
Public Property Checksum System.String

Gets and sets the property Checksum.

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.

Public Property Description System.String

Gets and sets the property Description.

A description of the slot type.

Public Property EnumerationValues System.Collections.Generic.List<Amazon.LexModelBuildingService.Model.EnumerationValue>

Gets and sets the property EnumerationValues.

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.

Public Property Name System.String

Gets and sets the property Name.

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.

Public Property ValueSelectionStrategy Amazon.LexModelBuildingService.SlotValueSelectionStrategy

Gets and sets the property ValueSelectionStrategy.

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.

Examples

This example shows how to create a slot type that describes pizza sauces.

To Create a Slot Type


var response = client.PutSlotType(new PutSlotTypeRequest 
{
    Name = "PizzaSauceType",
    Description = "Available pizza sauces",
    EnumerationValues = new List {
        new EnumerationValue { Value = "red" },
        new EnumerationValue { Value = "white" }
    }
});

string version = response.Version;
string name = response.Name;
string checksum = response.Checksum;
DateTime createdDate = response.CreatedDate;
string description = response.Description;
List enumerationValues = response.EnumerationValues;
DateTime lastUpdatedDate = response.LastUpdatedDate;
