profiles

Definition

Structured descriptions of a person or user — attributes, preferences, history — used to condition a model. In recommendation and personalization they are the conditioning input; in agent and simulation work they define personas that shape how an agent behaves. When systems generate profiles of real people rather than consume them, accuracy and privacy become the central concerns.
