Abstract

Reports on a project which aimed to simulate querying of an ideal system which could respond to any kind of questioning phrased in any way. 30 users accessed a system the knowledge base of which (unknown to them) included 2 human experts. The interactions between users and the system were logged and analyzed. The results reveal different information accessing strategies linked to individual user characteristics and retrieval effectiveness. Discusses implication for the design of improved information retrieval systems

Abstract

Describes an experiment conducted with 30 post graduate information science and librarianship students to discover how they might go about learning from an ideal database. A system was created which preserved the characteristics of a computer based environment, yet which freed itself from the constraints of current technology. The students were, in fact, interacting via computer screen with 2 human expert backed up with appropriate computer files and documentation. Results suggest a number of different information accessing strategies linked to relatively successful and less successful retrieval. Discusses the implications of the results for the design of computerized information retrieval systems
