Peer reviewedMarcus, Richard S. – Journal of the American Society for Information Science, 1983
Controlled experiments conducted to compare effectiveness of enhanced experimental computer intermediary system, CONIT, with that of human expert intermediary search specialists indicate that experimental intermediary techniques are now capable of providing search assistance whose effectiveness at least approximates that of human intermediaries in…

Peer reviewedThompson, David A. – Journal of the American Society for Information Science, 1971
The focus of this article is on the human interaction characteristics of an information retrieval system, some design considerations to improve man-machine cooperation, and a research system at Stanford that is exploring some of these techniques. (55 references) (Author/NH)

Peer reviewedCooper, Michael D. – Journal of the American Society for Information Science, 1983
Examines usage patterns of ELHILL retrieval program of National Library of Medicine's MEDLARS system. Based on sample of 6,759 searches, the study analyzes frequency of various commands, classifies messages issued by system, and investigates searcher error rates. Suggestions for redesigning program and query language are noted. Seven references…

Peer reviewedMeadow, Charles T.; And Others – Journal of the American Society for Information Science, 1982
Reports on the development of the Individualized Instruction for Data Access System (IIDA), a computer system designed at Drexel University, which serves as an intermediary enabling users to perform complex tasks on another computer. Capabilities of the instruction mode and assistance mode are discussed. Fifteen references are cited. (EJS)

Peer reviewedMeadow, Charles T.; And Others – Journal of the American Society for Information Science, 1982
Testing in an industrial setting of the Individualized Instruction for Data Access System--an intermediary system designed to train and assist users in conducting computer searches--demonstrates that end users can learn to do bibliographic searches through computer-assisted instruction that are as satisfactory as searches performed for them.…
