Information needs

In information science, library science, and information retrieval, an information need is person's gap in knowledge leading to a description of information they lack. It is closely related to relevance: if something is relevant for a person in relation to a given task, the person needs the information for that task. Information needs are related to, but distinct from information requirements. They are studied for: # The explanation of observed phenomena of information use or expressed need; # The prediction of instances of information uses; # The control and thereby improvement of the utilization of information manipulation of essential conditions.
