OAKDEC, a Program for Studying the Effects on Users of a Procedural Expert System for Database Searching.
Peer reviewed Peer reviewed
Meadow, Charles T. – Information Processing and Management, 1988
Describes OAKDEC, a program based on decision-making logic that uses expert system techniques to assess the status of a database search and to provide recommendations to the user on how to proceed. The discussion focuses on the use of OAKDEC as a research tool for studying user behavior. (20 references) (Author/CLB)

SHRIF, a General-Purpose System for Heuristic Retrieval of Information and Facts, Applied to Medical Knowledge Processing.
Peer reviewed Peer reviewed
Findler, Nicholas V.; And Others – Information Processing and Management, 1992
Describes SHRIF, a System for Heuristic Retrieval of Information and Facts, and the medical knowledge base that was used in its development. Highlights include design decisions; the user-machine interface, including the language processor; and the organization of the knowledge base in an artificial intelligence (AI) project like this one.

Information Retrieval from Hypertext: An Approach Using Plausible Inference.
Peer reviewed Peer reviewed
Lucarella, Dario; Zanzi, Antonella – Information Processing and Management, 1993
Discusses approaches to the integration of query-based information retrieval and browsing in a hypertext network. A prototype system developed to evaluate the proposed approach in terms of retrieval effectiveness and search efficiency is presented, and design and implementation issues concerning the prototype are considered.

BRAQUE: Design of an Interface to Support User Interaction in Information Retrieval.
Peer reviewed Peer reviewed
Belkin, Nicholas J.; And Others – Information Processing and Management, 1993
Discusses information retrieval as an inherently interactive process utilizing a variety of information-seeking strategies on informational and meta-informational levels. An interface design for a bibliographic information retrieval system, called BRAQUE (BRowsing And QUEry), that supports user interactions in a two-level hypertext environment is…

Towards a Cognitive Theory of Information Accessing: An Empirical Study.
Peer reviewed Peer reviewed
Ford, Nigel; Ford, Rosalind – Information Processing and Management, 1993
Discussion of information retrieval, knowledge representation, and computer-assisted learning focuses on a study that created a computer-based system designed to observe and record users' interactions with an ideal knowledge base consisting of unrevealed subject experts, appropriate documentation, and computer files. Information accessing…

Cognitive Process as a Basis for Intelligent Retrieval Systems Design.
Peer reviewed Peer reviewed
Chen, Hsinchun; Dhar, Vasant – Information Processing and Management, 1991
Two studies of the cognitive processes involved in online document-based information retrieval were conducted. These studies led to the development of five computational models of online document retrieval which were incorporated into the design of an "intelligent" document-based retrieval system. Both the system and the broader implications of…
