Development of IR Systems: New Direction.
Peer reviewed Peer reviewed
Frants, Valery I.; And Others – Information Processing & Management, 1996
Discusses improving the quality of satisfaction of information needs through the use of information retrieval systems. The characteristics of information need are investigated; a new instrument in information retrieval systems is proposed which takes into account different components of information need; and future research is suggested.…

The Need for Information and Some Aspects of Information Retrieval Systems Construction.
Peer reviewed Peer reviewed
Frants, Valery I.; Brush, Craig B. – Journal of the American Society for Information Science, 1988
Presents a model of human information needs which classifies information need types by their inherent properties. The influence of information needs on human behavior, and the need to incorporate this concept into information storage and retrieval systems, are discussed. (15 references) (CLB)

Multiversion Information Retrieval Systems and Feedback with Mechanism of Selection.
Peer reviewed Peer reviewed
Frants, Valery I.; And Others – Journal of the American Society for Information Science, 1993
Discusses the design of multiversion information retrieval systems and provides a theoretical justification for the necessity of creating such systems to perform an optimal search for the user's information needs. Topics discussed include comparing query formulations; feedback algorithms; an experiment with a test collection; and the mechanism of…
