Amazon Personalize announces the ability to filter (include or exclude) recommendations for Related Items recipes based on the properties of the input or query item (e.g. the CurrentItem). Prior to this launch, Personalize customers could filter items based on dataset properties such as category or price range. Customers could also filter recommendations based on properties of the user getting recommendations (e.g. the CurrentUser), such as age or whether or not the user had taken a specific action.
