Märgistaja

Märgistaja is an Estonian noun meaning a person who marks or labels something. It is formed from the verb märgistama "to mark or label" with an agent-noun suffix, yielding the name of a role or activity—the one who marks.

In practical use, a märgistaja may label physical objects, such as goods with tags or signs, or designate information on a plan or map. The term is also common in information processing contexts, where a märgistaja annotates data—such as images, text, or audio—to create labeled datasets for training machine learning models.

Linguistically and in everyday language, märgistaja is a neutral job-related term. Context usually clarifies whether the marking is for logistics, inventory, archiving, cartography, or data annotation. In modern workplaces, the role can appear in diverse fields, including retail, logistics, libraries or archives, and data science teams.

Etymology and usage notes: the word reflects the predicate märgistama (to mark or label) and denotes an agent performing the action. While the exact duties vary by industry, the core idea is consistently the creation of marks, labels, or tags that identify, categorize, or describe items or data.
