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…

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…

Considers approaches to dealing with user attitudes toward newly implemented information systems (IS), and suggests that behavioral management strategies relevant to IS fall into three categories: (1) empirical/rational; (2) normative/reeducative; and (3) power/coercive, based on "planned change" theories. An integrative contingent model…

Presents an Intelligent Negotiating Neural Network Design Model for solving the problem of poor information retrieval in subject searches of online catalogs. The purpose of the network, its architecture, and three different sessions of the user interface are described. Nineteen figures showing screens of the three sessions are appended. (Contains…
