What are on call annotation jobs?

On call annotation jobs involve labeling or tagging data—such as images, audio, text, or video—on an as-needed basis, usually for use in machine learning and artificial intelligence projects. Workers are contacted or scheduled to work only when annotation tasks become available, making the job highly flexible but inconsistent in hours. These roles typically require attention to detail and the ability to follow specific guidelines, as accuracy is crucial for training AI systems. On call annotation jobs can be performed remotely, and may involve using specialized annotation tools provided by employers or clients.
