annotator

This term describes a role centered on adding metadata or explanatory layers to a primary source. In academic and literary contexts, it implies a high degree of scholarly expertise, where the annotator acts as a bridge between a difficult historical text and a modern reader.

In the contemporary tech industry, the term has shifted toward data science. Here, it refers to the repetitive process of labeling raw data to train AI. While the academic annotator provides interpretation, the technical annotator provides classification, often working within a structured framework to ensure consistency for machine learning algorithms.
