Recommendation reasons (User-Personalization-v2)

If you use User-Personalization-v2, each recommended item can include list of reasons for why the item was included in recommendations. Possible reasons include the following

  • Promoted item – Indicates the item was included as part of a promotion that you applied in your recommendation request.

  • Exploration – Indicates the item was included with exploration. With exploration, recommendations include items with less interactions data or relevance for the user. For more information about exploration, see Exploration.

  • Popular item – Indicates the item was included as a placeholder popular item. If you use a filter, depending on how many recommendations the filter removes, Amazon Personalize might add placeholder items to meet the numResults for your recommendation request. These items are popular items, based on interactions data, that satisfy your filter criteria. They don't have a relevance score for the user.
