Role and duties: A tagamisest spetsialisti creates labels for data types such as images, text, audio, and video; develops and follows annotation guidelines; performs quality control; resolves ambiguities; collaborates with data scientists; maintains documentation and metadata; ensures data privacy and ethical standards.

Skills and training: Typical requirements include attention to detail, domain knowledge, ability to follow precise guidelines, and familiarity with annotation tools (for example CVAT, Labelbox, Supervisely). Strong communication and teamwork are important for coordinating with data science teams.

Industry and impact: The role has grown with the expansion of AI and ML, with workers employed in technology companies, research laboratories, and government data programs. The quality of model performance often depends on annotation quality and inter-annotator agreement, making standardization and clear protocols central to the work.

Challenges and developments: Tagamisest spetsialisti work can raise privacy considerations, bias risk, and workload pressures.
