How to Create a Categorization Project

This section shows you how to create a Mechanical Turk Categorization project. Categorization projects are different from the other project templates listed on the Create page.

A Categorization project includes everything you need: predesigned HITs that do not require editing in HTML, pre-qualified Master Workers who have demonstrated expertise in categorization HITs, price recommendations based on comparable HITs in the Mechanical Turk marketplace and analysis tools that make it easy to verify results and identify gaps in instructions that may be causing Worker confusion.

The following procedure describes in detail how to create a categorization project.

To create a categorization project

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

  2. From the list under Start a New Project, click Categorization, and then click Create Project.

    Create Tab - Categorization Selected

  3. On the Choose Categories page, fill in the page according to the specifics of your project and then click Next.

  4. On the Upload File page, click Choose File to locate the .csv data file that you want to upload and then click Upload. For information about creating a HIT csv data file, see Create your HIT data file in How to Create a Project.

    Upload File

  5. After your data file is uploaded, select the columns from your csv data file that you want to show to Workers and select whether the column contains text, a link to an image or a link to a website. Click Next.

    Upload File Complete

  6. The Preview page shows you how your categorization items will look to Workers. If you find something you want to change in the preview, click Go back and edit.

  7. If you are satisfied with the preview, click Continue.

  8. On the Pricing and Checkout page, review the pricing information for your project. Mechanical Turk recommends a Worker reward price based on the complexity of the categorization task and the price of similar HITs on the Mechanical Turk marketplace. You can change the Reward per Submission price. After you set the price you want, click Publish.

    Finish
  9. You'll receive an email when your categorization project has been completed. The email contains a link to the Requester website so you can pick up your results. For more information about retrieving results for your project, see Managing Batches.
