These topics help you set up a Ground Truth labeling job that uses a custom labeling template. A custom labeling template allows you to create a custom worker portal UI that workers will use to label data. Template can be created using HTML, CSS, JavaScript, Liquid template language, and Crowd HTML Elements.

Overview

If this is your first time creating a custom labeling workflow in Ground Truth, the following list is a high-level summary of the steps required.

  1. Set up your workforce – To create a custom labeling workflow you need a workforce. This topic teaches you about configuring a workforce.

  2. Creating a custom template – To create a custom template you must map the data from your input manifest file correctly to the variables in your template.

  3. Using optional processing Lambda functions – To control how data from your input manifest is added to your worker template, and how worker annotations are logged in your job's output file.
