get_personalized_ranking(campaign_arn, input_list, user_id)
get_personalized_ranking(campaign_arn, input_list, user_id, params::Dict{String,<:Any})

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.

Arguments

• campaign_arn: The Amazon Resource Name (ARN) of the campaign to use for generating the personalized ranking.
• input_list: 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.
• user_id: The user for which you want the campaign to provide a personalized ranking.

Optional Parameters

Optional parameters can be passed as a params::Dict{String,<:Any}. Valid keys are:

• "context": 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": 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": 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 INCLUDE element to include items, you must provide values for all parameters that are defined in the expression. For filters with expressions that use an EXCLUDE element to exclude items, you can omit the filter-values.In this case, Amazon Personalize doesn't use that portion of the expression to filter recommendations. For more information, see Filtering Recommendations.

get_recommendations()
get_recommendations(params::Dict{String,<:Any})

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: USERPERSONALIZATION - userId required, itemId not used RELATEDITEMS - itemId required, userId not 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.

Optional Parameters

Optional parameters can be passed as a params::Dict{String,<:Any}. Valid keys are:

• "campaignArn": The Amazon Resource Name (ARN) of the campaign to use for getting recommendations.
• "context": 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": The ARN of the filter to apply to the returned recommendations. For more information, see Filtering Recommendations. When using this parameter, be sure the filter resource is ACTIVE.
• "filterValues": 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 INCLUDE element to include items, you must provide values for all parameters that are defined in the expression. For filters with expressions that use an EXCLUDE element to exclude items, you can omit the filter-values.In this case, Amazon Personalize doesn't use that portion of the expression to filter recommendations. For more information, see Filtering recommendations and user segments.
• "itemId": The item ID to provide recommendations for. Required for RELATED_ITEMS recipe type.
• "numResults": The number of results to return. The default is 25. The maximum is 500.
• "promotions": The promotions to apply to the recommendation request. A promotion defines additional business rules that apply to a configurable subset of recommended items.
• "recommenderArn": The Amazon Resource Name (ARN) of the recommender to use to get recommendations. Provide a recommender ARN if you created a Domain dataset group with a recommender for a domain use case.
• "userId": The user ID to provide recommendations for. Required for USER_PERSONALIZATION recipe type.
