Publishing a Batch

Publishing your HITs on the Amazon Mechanical Turk web page gives Workers the opportunity to work on them. If your project template contains variables, you must upload the .csv data file that supplies the values for the variables in each HIT before you can publish your batch of HITs.

How to Publish a Batch

This section shows you how to publish an Amazon Mechanical Turk batch. The following procedure describes in detail how to publish a batch using an existing project.

To publish a batch

  1. On the Mechanical Turk Requester website https://requester.mturk.com/, click the Create tab and then click New Batch with an Existing Project.

    Create Tab - New Batch
  2. Under Start a New Batch with an Existing Project, click Publish Batch to publish the batch for your project. (If you want to make edits to your project before publishing a new batch, click Edit to make changes to the HIT properties or design layout.)

    Publish Batch
  3. If your project template contains variables, you'll be asked to choose a .csv file to upload. On the Publish Batch dialog box, click Choose File to locate the .csv data file and then click Upload. (If your HIT template does not contain variables, the HIT Preview page appears, as shown in Step 5.)

    Choose File
  4. After your file uploads, click Next to preview how your HITs will appear to Workers.

  5. On the Preview HITs page, carefully review your HITs so that you catch mistakes before publishing. For example, make sure that any variables in the HIT are correctly replaced by your input data. Click Next HIT to preview the next HIT. You can preview up to 200 HITs in your data file.

    Preview HITs
  6. After you finish reviewing your HITs, click Next.

    The Confirm and Publish Batch page shows the total amount you will pay Workers and Mechanical Turk, if you approve all of the assignments.

    Confirm and Publish

    The following table explains the sections of the Confirm and Publish Batch page.

    Section Description
    Batch Properties Contains the values that you set on the Design tab for the batch properties, including the number of days the batch can exist before expiring, and the number of days you have to reject an assignment submitted by a Worker before the assignment is auto-approved and the Worker is paid.
    HITs Calculates the number of assignments per batch.
    Cost Calculates the cost of the batch assuming you approve all assignments. The total cost is the number of assignments multiplied by the price per assignment plus the Mechanical Turk fee. You must have enough money in your account to cover the total cost before you can publish the HIT. If you don't, you'll be asked to add money to your account.
  7. Click Publish HITs to publish the batch of HITs.

  8. You can track the progress of the publishing of your batch on the Batch Details page. For more information about managing batches, see Managing Batches.
