Amazon Personalize Runtime 2018-05-22
- Client: Aws\PersonalizeRuntime\PersonalizeRuntimeClient
- Service ID: personalize-runtime
- Version: 2018-05-22
This page describes the parameters and results for the operations of the Amazon Personalize Runtime (2018-05-22), and shows how to use the Aws\PersonalizeRuntime\PersonalizeRuntimeClient object to call the described operations. This documentation is specific to the 2018-05-22 API version of the service.
Operation Summary
Each of the following operations can be created from a client using
$client->getCommand('CommandName'), where "CommandName" is the
name of one of the following operations. Note: a command is a value that
encapsulates an operation and the parameters used to create an HTTP request.
You can also create and send a command immediately using the magic methods
available on a client object: $client->commandName(/* parameters */).
You can send the command asynchronously (returning a promise) by appending the
word "Async" to the operation name: $client->commandNameAsync(/* parameters */).
- GetPersonalizedRanking ( array $params = [] )
Re-ranks a list of recommended items for the given user.
- GetRecommendations ( array $params = [] )
Returns a list of recommended items.
Operations
GetPersonalizedRanking
$result = $client->getPersonalizedRanking([/* ... */]); $promise = $client->getPersonalizedRankingAsync([/* ... */]);
Re-ranks a list of recommended items for the given user. The first item in the list is deemed the most likely item to be of interest to the user.
The solution backing the campaign must have been created using a recipe of type PERSONALIZED_RANKING.
Parameter Syntax
$result = $client->getPersonalizedRanking([
'campaignArn' => '<string>', // REQUIRED
'context' => ['<string>', ...],
'filterArn' => '<string>',
'filterValues' => ['<string>', ...],
'inputList' => ['<string>', ...], // REQUIRED
'userId' => '<string>', // REQUIRED
]);
Parameter Details
Members
- campaignArn
-
- Required: Yes
- Type: string
The Amazon Resource Name (ARN) of the campaign to use for generating the personalized ranking.
- context
-
- Type: Associative array of custom strings keys (AttributeName) to strings
The contextual metadata to use when getting recommendations. Contextual metadata includes any interaction information that might be relevant when getting a user's recommendations, such as the user's current location or device type.
- filterArn
-
- Type: string
The Amazon Resource Name (ARN) of a filter you created to include items or exclude items from recommendations for a given user. For more information, see Filtering Recommendations.
- filterValues
-
- Type: Associative array of custom strings keys (FilterAttributeName) to strings
The values to use when filtering recommendations. For each placeholder parameter in your filter expression, provide the parameter name (in matching case) as a key and the filter value(s) as the corresponding value. Separate multiple values for one parameter with a comma.
For filter expressions that use an
INCLUDEelement to include items, you must provide values for all parameters that are defined in the expression. For filters with expressions that use anEXCLUDEelement to exclude items, you can omit thefilter-values.In this case, Amazon Personalize doesn't use that portion of the expression to filter recommendations.For more information, see Filtering Recommendations.
- inputList
-
- Required: Yes
- Type: Array of strings
A list of items (by
itemId) to rank. If an item was not included in the training dataset, the item is appended to the end of the reranked list. The maximum is 500. - userId
-
- Required: Yes
- Type: string
The user for which you want the campaign to provide a personalized ranking.

- Type: Array of PredictedItem structures
A list of items in order of most likely interest to the user. The maximum is 500.
- recommendationId
-
- Type: string
The ID of the recommendation.
Errors
-
Provide a valid value for the field or parameter.

GetRecommendations
$result = $client->getRecommendations([/* ... */]); $promise = $client->getRecommendationsAsync([/* ... */]);
Returns a list of recommended items. For campaigns, the campaign's Amazon Resource Name (ARN) is required and the required user and item input depends on the recipe type used to create the solution backing the campaign as follows:
-
USER_PERSONALIZATION -
userIdrequired,itemIdnot used -
RELATED_ITEMS -
itemIdrequired,userIdnot used
Campaigns that are backed by a solution created using a recipe of type PERSONALIZED_RANKING use the API.
For recommenders, the recommender's ARN is required and the required item and user input depends on the use case (domain-based recipe) backing the recommender. For information on use case requirements see Choosing recommender use cases.
Parameter Syntax
$result = $client->getRecommendations([
'campaignArn' => '<string>',
'context' => ['<string>', ...],
'filterArn' => '<string>',
'filterValues' => ['<string>', ...],
'itemId' => '<string>',
'numResults' => <integer>,
'recommenderArn' => '<string>',
'userId' => '<string>',
