User Interface Models for Multidisciplinary Bibliographic Information Dissemination Centers.
Zipperer, W. C.
Two information dissemination centers at University of California at Los Angeles and University of Georgia studied the interactions between computer based search facilities and their users. The study, largely descriptive in nature, investigated the interaction processes between data base users and profile analysis or information specialists in constructing and revising search profiles. Data were gathered from users, intermediaries, and tape-recording search request interview sessions. Interview events were identified, labeled, and analyzed, and transition matrices were constructed for major groupings of events. On the basis of the data presearch and postsearch models of existing interfaces were constructed. The study indicated a need for data base information support, accommodation of a wide range of users, human intermediaries, built-in diagnostic capabilities, and alternative interaction mechanisms for the user. Results of the study showed that interface for the two centers was not linear, was highly adaptive, and had an important instructional component. Particularly significant was the finding that the human intermediary is an integral part of the interface essential to its adaptive capability. (Author/LS)
