Then, publish the collection so that you can use it to evaluate a skill in AI Skill Kit. ## Before you begin At least one dataset must exist. To learn more, see . Role required: sn\_data\_kit.admin ## About this task A data collection is the object that AI Skill Kit uses to evaluate a skill. A collection can combine records from more than one dataset. ## Procedure 1. Navigate to **All** > **AI Data Kit** > **Home**. 2. In the An overview of your data assets section, on the **Datasets** tab, select the dataset that contains the records that you want. If the dataset isn't listed, select **View all datasets**. 3. At the top of the dataset page, select **Add to data collection**. - To create a collection, enter a name in the **Data collection name** field. Optionally, enter a description, and add tags by typing each tag and pressing Enter. - To add the dataset to an existing collection, turn off the **Create data collection** toggle. Then select the collection from the **Available data collection** field. 4. Select **Confirm**. The Add to data collection page opens, with a Choose columns section and a Choose records section. 5. In the Choose columns section, select the columns that you want to add to the data collection, and then select **Save & next**. 6. In the Choose records section, select a selection method. |Selection method|Action| |----------------|------| |**__Manual selection__**|Select the check box for each record that you want to include. If you don't select any records, all records in the dataset are added to the collection.| |**__Sampling selection__**|In the **Sample size** field, enter the number of records to include, and then select **Run**. **Random sampling** is the only sampling method. The sampled records appear in the records list.| 7. At the bottom of the page, select **Add to data collection**. For sampling selection, this button is available only after you run the sample. Adding a dataset to a collection changes the dataset's state to Published. You can't edit or delete the records in a published dataset. The data collection page opens. 8. Select **Publish data collection**. When you publish a collection, the collection freezes curation and becomes available for use through AI Skill Kit. 9. Select **Confirm** to make your collection available. The data collection is published. ## What to do next Select the published data collection in AI Skill Kit and run the evaluation. You can also use a published data collection as the source for a labeling project, which adds ground truth to its records. Labeling projects can only use published collections.
