Peer reviewedFrants, Valery I.; Shapiro, Jacob – Journal of the American Society for Information Science, 1991
Discussion of the problem of control in documentary information retrieval (IR) systems focuses on feedback mechanisms. Information needs are discussed, particularly the Problem Oriented Information Need (POIN); the structure of an adaptive IR system is described; and the design of algorithms for automated IR systems is explained.
