    • Create a smaller, derived dataset from an existing dataset using Now Assist Data Kit. Use derived datasets to isolate specific records for focused ground truth labeling or evaluation without modifying the original dataset.

    Before you begin

    Role required: sn_data_kit.admin

    Procedure

    1. Navigate to All > Now Assist Data Kit > Home, and open an existing dataset in the Datasets tab.
    2. Select the Create derived dataset button at the top of the Records list.
    3. In the Add dataset info section, fill in the fields.
      Create derived dataset form
      Table 1. Add dataset info fields
      Field Description
      Dataset name Name of the derived dataset.
      Dataset description Description of the derived dataset. This field is pre-populated with a reference to the parent dataset.
      Tags Keywords to help identify and search for the dataset.
    4. In the Choose records section, select a selection method and choose the records to include.

      A minimum of 10 records must be selected before you can create the dataset.

      • Manual Selection: Select the check box next to each record you want to include.
      • Sampling Selection: Select a sampling method from the drop-down menu, enter a number in the sample size box, and select Run to preview the sampled records.
    5. Select Create dataset.
      The derived dataset is added as a separate dataset.

    What to do next

    After you have created the derived dataset, you can add ground truth to its records. For more information, see Add a ground truth to each dataset record.
