Elicitation

Elicitation refers to the method or mechanism of obtaining required information from users, domain experts, or systems through active questioning, dialogue, or structured approaches during information interaction or system design. It is widely applied in requirements engineering, knowledge engineering, human-computer interaction, and AI system design. Core characteristics include interactivity through dynamic two-way communication, goal orientation toward targeted acquisition of missing information, and incrementality through step-by-step collection of needed content on demand.
