Getting started with a Domain dataset group (console)

In this exercise, you use the Amazon Personalize console to create a Domain dataset group and a recommender that returns movie recommendations for a given user.

Before you start this exercise, review the Getting started prerequisites.

When you finish the getting started exercise, to avoid incurring unnecessary charges, delete the resources that you created. For more information, see Requirements for deleting Amazon Personalize resources.

In this procedure you create Domain dataset group for the VIDEO_ON_DEMAND domain, create an Item interactions dataset with the default schema for the VIDEO_ON_DEMAND domain, and import the item interactions data you created in Creating the training data (Domain dataset group).

  1. Open the Amazon Personalize console at https://console.amazonaws.cn/personalize/home and sign in to your account.

  2. In the navigation pane, choose Create dataset group.

  3. In Dataset group details, specify a name for your dataset group.

  4. For Domain, choose Video on demand. The domain you choose determines the default schema you use when importing data. It also determines what use cases are available for recommenders. Your screen should look similar to the following.

    Depicts Create dataset group page with Name and Domain fields.

  5. Choose Create dataset group. The Overview page appears. Proceed to Step 2: Import data.

In this procedure you create an Item interactions dataset with the default VIDEO_ON_DEMAND domain schema. Then you import the item interactions data you created in Creating the training data (Domain dataset group).

To import data

  1. On the Overview page, in Step 1. Create datasets and import data, choose Create dataset and choose Item interactions dataset.

  5. Review the recommender details and choose Create recommenders to create your recommender.

    You can monitor the status of each recommender on the Recommenders page. When your recommender status is Active, you can use it to get recommendations in Step 4: Get recommendations.

In this procedure you use the recommender that you created in the previous step to get recommendations.

To get recommendations

  1. On the Overview page for your Domain dataset group, in the navigation pane choose Recommenders.

  2. On the Recommenders page, choose your recommender.

  3. At the top right, choose Test.

  4. In Recommendation parameters, enter a user ID. Leave the other fields unchanged.
