This report investigates seven document representations--configurations of controlled and free-text vocabulary--which can be used to search the INSPEC (Computer and Control Abstracts) and PsychInfo (Psychological Abstracts) databases. The performance of each representation is analyzed, as is overlap among the representations, i.e., the extent to…

This exploratory investigation of the process of defining the information needs of computer users and the impact of that process on information retrieval focuses on communication problems. Six sites were visited that used computers to process data or to provide information, including the California Department of Transportation, the California…

Develops model of the reference interview which explicitly incorporates human information processing, particularly schema ideas presented by Marvin Minsky and other theorists in cognitive processing and artificial intelligence. Questions are raised concerning use of content analysis of transcribed verbal protocols as methodology for studying…

Issues involved in integrating new methods of bibliographic and physical access with old ones to create a unified system of periodical article access and identification are identified. Desirable characteristics of a system, a possible model, and suggestions for further research are presented. (Author/JKP)

Analyzes the search process, isolating the pertinent elements that make up a search and identifying the many decision points in the process. (Author/PF)

Compares the traditional model of the reference interview with a new model based on online information process. Findings offer new perspectives on the reference interview process and lend support to the adoption of a new reference model which shifts its venue from a person to person process, to one in which information itself provides the platform…

Explains the imposed query model of information seeking and incorporates findings and implications surrounding work on imposed queries into reference work with children. Highlights include a developmental view; types of reference questions; relevance; information services for children; stereotyping; modeling search behavior; and evaluating…

Explores the potential impact of imposed query, a new model of information-seeking behavior, on current approaches to library service and system evaluation. Discusses reference service evaluation, user studies, output measures, and relevance as an evaluation tool. Argues that imposed query broadens understanding of the user and of the role that…

Examines the usefulness of the Eisenberg-Berkowitz Information Problem-Solving model as a categorization for academic reference encounters. Major trends in the data include a high proportion of questions about location and access of sources, lack of synthesis or production activities, and consistent presence of system problems that impede the…

Two aspects of Karl Popper's philosophy are applied to reference process: process is viewed as series of problem-solving situations amenable to analysis using Popper's problem-solving schema. Reference interview is analyzed in context of Popper's postulate that books contain autonomous world of ideas existing apart from mind of knower. (30…

Presents a description of PLEXUS, an expert system on gardening designed as a referral tool for public libraries by the University of London. Highlights include determining user characteristics, developing the problem statement, the use of semantic categories, and search strategies that modify the original problem statement using Boolean…

Examines advantages and disadvantages of the traditional model of undifferentiated service versus an alternative model of differentiated services, which includes directions and general information; technical assistance, "information lookup" for the client, research consultation, and library instruction. Suggests each service should fit…

Three papers based on projects produced in a course entitled Operations Research and Library Management, jointly sponsored by the Department of Mechanical and Industrial Engineering and the Graduate School of Library Science are reported and explained. Topics covered include an assessment of faculty interest in an information retrieval service;…

Discusses the development of practical strategies for library mediation between Internet resources and potential users. Topics addressed include a hierarchy of information skills; awareness of information services and resources; the information structure of a discipline; analysis of information needs; and retrieval, evaluation, and management of…

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…
