2021/04/01 - Amazon Lex Model Building Service - 6 updated api methods
Changes Lex now supports the ja-JP locale
{'locale': {'ja-JP'}}
Creates a new version of the bot based on the $LATEST version. If the $LATEST version of this resource hasn't changed since you created the last version, Amazon Lex doesn't create a new version. It returns the last created version.
Note
You can update only the $LATEST version of the bot. You can't update the numbered versions that you create with the CreateBotVersion operation.
When you create the first version of a bot, Amazon Lex sets the version to 1. Subsequent versions increment by 1. For more information, see versioning-intro .
This operation requires permission for the lex:CreateBotVersion action.

Request Syntax
client.create_bot_version(
name='string',
checksum='string'
)
string
[REQUIRED]
The name of the bot that you want to create a new version of. The name is case sensitive.
string
Identifies a specific revision of the $LATEST version of the bot. If you specify a checksum and the $LATEST version of the bot has a different checksum, a PreconditionFailedException exception is returned and Amazon Lex doesn't publish a new version. If you don't specify a checksum, Amazon Lex publishes the $LATEST version.

{'locale': {'ja-JP'}}
Creates an Amazon Lex conversational bot or replaces an existing bot. When you create or update a bot you are only required to specify a name, a locale, and whether the bot is directed toward children under age 13. You can use this to add intents later, or to remove intents from an existing bot. When you create a bot with the minimum information, the bot is created or updated but Amazon Lex returns the response FAILED . You can build the bot after you add one or more intents. For more information about Amazon Lex bots, see how-it-works .
If you specify the name of an existing bot, the fields in the request replace the existing values in the $LATEST version of the bot. Amazon Lex removes any fields that you don't provide values for in the request, except for the idleTTLInSeconds and privacySettings fields, which are set to their default values. If you don't specify values for required fields, Amazon Lex throws an exception.
This operation requires permissions for the lex:PutBot action. For more information, see security-iam .

string
[REQUIRED]
The name of the bot. The name is not case sensitive.
string
A description of the bot.
list
An array of Intent objects. Each intent represents a command that a user can express. For example, a pizza ordering bot might support an OrderPizza intent. For more information, see how-it-works .
(dict) --
Identifies the specific version of an intent.
intentName (string) -- [REQUIRED]
The name of the intent.
intentVersion (string) -- [REQUIRED]
The version of the intent.
boolean
Set to true to enable access to natural language understanding improvements.
When you set the enableModelImprovements parameter to true you can use the nluIntentConfidenceThreshold parameter to configure confidence scores. For more information, see Confidence Scores .
You can only set the enableModelImprovements parameter in certain Regions. If you set the parameter to true , your bot has access to accuracy improvements.
The Regions where you can set the enableModelImprovements parameter to true are:
US East (N. Virginia) (us-east-1)
US West (Oregon) (us-west-2)
Asia Pacific (Sydney) (ap-southeast-2)
EU (Ireland) (eu-west-1)
In other Regions, the enableModelImprovements parameter is set to true by default. In these Regions setting the parameter to false throws a ValidationException exception.
float
Determines the threshold where Amazon Lex will insert the AMAZON.FallbackIntent , AMAZON.KendraSearchIntent , or both when returning alternative intents in a PostContent or PostText response. AMAZON.FallbackIntent and AMAZON.KendraSearchIntent are only inserted if they are configured for the bot.
You must set the enableModelImprovements parameter to true to use confidence scores in the following regions.
US East (N. Virginia) (us-east-1)
US West (Oregon) (us-west-2)
Asia Pacific (Sydney) (ap-southeast-2)
EU (Ireland) (eu-west-1)
In other Regions, the enableModelImprovements parameter is set to true by default.
For example, suppose a bot is configured with the confidence threshold of 0.80 and the AMAZON.FallbackIntent . Amazon Lex returns three alternative intents with the following confidence scores: IntentA (0.70), IntentB (0.60), IntentC (0.50). The response from the PostText operation would be:
AMAZON.FallbackIntent
IntentA
IntentB
IntentC
dict
When Amazon Lex doesn't understand the user's intent, it uses this message to get clarification. To specify how many times Amazon Lex should repeat the clarification prompt, use the maxAttempts field. If Amazon Lex still doesn't understand, it sends the message in the abortStatement field.
When you create a clarification prompt, make sure that it suggests the correct response from the user. for example, for a bot that orders pizza and drinks, you might create this clarification prompt: "What would you like to do? You can say 'Order a pizza' or 'Order a drink.'"
If you have defined a fallback intent, it will be invoked if the clarification prompt is repeated the number of times defined in the maxAttempts field. For more information, see AMAZON.FallbackIntent .
If you don't define a clarification prompt, at runtime Amazon Lex will return a 400 Bad Request exception in three cases:
Follow-up prompt - When the user responds to a follow-up prompt but does not provide an intent. For example, in response to a follow-up prompt that says "Would you like anything else today?" the user says "Yes." Amazon Lex will return a 400 Bad Request exception because it does not have a clarification prompt to send to the user to get an intent.
Lambda function - When using a Lambda function, you return an ElicitIntent dialog type. Since Amazon Lex does not have a clarification prompt to get an intent from the user, it returns a 400 Bad Request exception.
PutSession operation - When using the PutSession operation, you send an ElicitIntent dialog type. Since Amazon Lex does not have a clarification prompt to get an intent from the user, it returns a 400 Bad Request exception.
messages (list) -- [REQUIRED]
An array of objects, each of which provides a message string and its type. You can specify the message string in plain text or in Speech Synthesis Markup Language (SSML).
(dict) --
The message object that provides the message text and its type.
contentType (string) -- [REQUIRED]
The content type of the message string.
content (string) -- [REQUIRED]
The text of the message.
groupNumber (integer) --
Identifies the message group that the message belongs to. When a group is assigned to a message, Amazon Lex returns one message from each group in the response.
maxAttempts (integer) -- [REQUIRED]
The number of times to prompt the user for information.
responseCard (string) --
A response card. Amazon Lex uses this prompt at runtime, in the PostText API response. It substitutes session attributes and slot values for placeholders in the response card. For more information, see ex-resp-card .
dict
When Amazon Lex can't understand the user's input in context, it tries to elicit the information a few times. After that, Amazon Lex sends the message defined in abortStatement to the user, and then cancels the conversation. To set the number of retries, use the valueElicitationPrompt field for the slot type.
For example, in a pizza ordering bot, Amazon Lex might ask a user "What type of crust would you like?" If the user's response is not one of the expected responses (for example, "thin crust, "deep dish," etc.), Amazon Lex tries to elicit a correct response a few more times.
For example, in a pizza ordering application, OrderPizza might be one of the intents. This intent might require the CrustType slot. You specify the valueElicitationPrompt field when you create the CrustType slot.
If you have defined a fallback intent the cancel statement will not be sent to the user, the fallback intent is used instead. For more information, see AMAZON.FallbackIntent .
messages (list) -- [REQUIRED]
A collection of message objects.
(dict) --
The message object that provides the message text and its type.
contentType (string) -- [REQUIRED]
The content type of the message string.
content (string) -- [REQUIRED]
The text of the message.
groupNumber (integer) --
Identifies the message group that the message belongs to. When a group is assigned to a message, Amazon Lex returns one message from each group in the response.
responseCard (string) --
At runtime, if the client is using the PostText API, Amazon Lex includes the response card in the response. It substitutes all of the session attributes and slot values for placeholders in the response card.
integer
The maximum time in seconds that Amazon Lex retains the data gathered in a conversation.
A user interaction session remains active for the amount of time specified. If no conversation occurs during this time, the session expires and Amazon Lex deletes any data provided before the timeout.
For example, suppose that a user chooses the OrderPizza intent, but gets sidetracked halfway through placing an order. If the user doesn't complete the order within the specified time, Amazon Lex discards the slot information that it gathered, and the user must start over.
If you don't include the idleSessionTTLInSeconds element in a PutBot operation request, Amazon Lex uses the default value. This is also true if the request replaces an existing bot.
The default is 300 seconds (5 minutes).
string
The Amazon Polly voice ID that you want Amazon Lex to use for voice interactions with the user. The locale configured for the voice must match the locale of the bot. For more information, see Voices in Amazon Polly in the Amazon Polly Developer Guide .
string
Identifies a specific revision of the $LATEST version.
When you create a new bot, leave the checksum field blank. If you specify a checksum you get a BadRequestException exception.
When you want to update a bot, 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
If you set the processBehavior element to BUILD , Amazon Lex builds the bot so that it can be run. If you set the element to SAVE Amazon Lex saves the bot, but doesn't build it.
If you don't specify this value, the default value is BUILD .
string
[REQUIRED]
Specifies the target locale for the bot. Any intent used in the bot must be compatible with the locale of the bot.
The default is en-US .
