Recommendation Engine task

Last Updated: Apr 10, 2018

The Recommendation Engine node is used to call the data computing tasks created in the Recommendation Engine products, and perform scheduling production according to the node configuration. Recommendation Engine node tasks can only be added in DataWorks after the businesses and scenarios are created in Recommendation Engine and the corresponding algorithm configurations are completed.

Create business scenarios in Recommendation Engine

Only the business scenarios that can be searched in Recommendation Engine can be loaded into the Recommendation Engine nodes.


You can only see the Recommendation Engine task node after Recommendation Engine is enabled.

Create Recommendation Engine nodes

  1. On the Data Development page, click New and select Create Task.

  2. Complete the configurations in the Create Task dialog box. In this example, select Node Task as the task type and Recommendation Engine as the type. The other configurations are shown as follows:

  3. Click Create.

  4. Click Save and Submit to complete the periodic scheduling of Recommendation Engine tasks.

View logs

You can query the corresponding computing tasks on the View Log page of the Recommendation Engine products.

  • Data preprocessing: Used to import raw data into the recommendation standard table. Data preprocessing tasks need to be completed before performing algorithm computing and performance computing tasks.

  • Algorithm computing: Used to start the configured algorithm strategy in Recommendation Engine business scenarios.

  • Data preprocessing + algorithm computing: An integrated task including data preprocessing and algorithm computing.

  • Performance computing: Used to start the performance report computing of specified business in Recommendation Engine.
