Uses and sources of voice indexing (a look-up feature for recorded materials) are discussed. Voice indexing enables a blind user of audiocassettes to find specific sections of recorded text independently. A procedure for sequential voice indexing on a two-track or four-track cassette recorder is described. (JW)

Reviews different structures and techniques of knowledge representation: structure of database records and files, data structures in computer programming, syntatic and semantic structure of natural language, knowledge representation in artificial intelligence, and models of human memory. A prototype expert system that makes use of some of these…

Intended to assist library educators, vendor representatives, end-user trainers, and experienced searchers, this article examines typical problems encountered by students in learning online searching. Problems with database selection, search tactics, and using the search system are highlighted, and a sample online exercise and search request form…

Description of database management systems for microcomputers highlights system features and factors to consider in microcomputer system selection. A method for ranking database management systems is explained and applied to a defined need, i.e., software support for indexing a weekly newspaper. A glossary of terms and 32-item bibliography are…

Describes the ERIC (Educational Resources Information Center) system, how it is organized, how to gain access to ERIC, how one uses RIE (Resources in Education) and CIJE (Current Index to Journals in Education), computer searches of ERIC, who publishes in ERIC, and how to learn more about ERIC. A sample ERIC resume is included. (CT)

Discusses the need for knowledge gateway systems to provide access to scattered information and the use of technologies in gateway building, including artificial intelligence and expert systems, networking, online retrieval systems, optical storage, and natural language processing. The status of four existing gateways is described. (20 references)…

Describes an experiment that tested the effects of a vertical versus a horizontal arrangement of brief structured text entries on know-item search time. The results discussed include the effects of the searcher's age and entry arrangement on search times, and subjects' judgments on the ease of use of the entry arrangements. (Author/CLB)

Describes and discusses the findings of an experiment that tested the precision of full-text retrieval enhanced by 29 document term weighting algorithms at the lowest, middle, and highest levels of recall, and compared with the precision of full-text retrieval without algorithms and with paragraph retrieval. (29 references) (Author/CLB)

Categorizes software packages for microcomputer database creation by their typical features and strengths, and discusses appropriate applications of each category. A directory of vendors for each type of software--text retrieval, file managers, database management, information storage and retrieval, integrated bibliographic systems, and library…

Describes CANSEARCH, an intermediary computer system incorporating fundamental features of the expert systems approach. Designed to provide access to information on cancer therapy in the MEDLINE database for doctors with no experience in document retrieval, search strategies are explained and menu selection from a touch terminal is illustrated.…

Describes a microcomputer-based software package, Online Search Tutor (OST), which is designed to teach users online bibliographic searching. Modeled on software previously developed for the European Space Agency Information Retrieval Services (ESA-IRS), OST includes a database of 600 bibliographic records which will simulate actual search…

A survey of Library of Congress staff following implementation of four optical disk reader stations measured their satisfaction with training, documentation, equipment and printing, and system reliability and usefulness. Staff found no major flaws with the system, and they saw its usefulness primarily as an access tool. (CDD)

Reviews recent progress in the development and use of online retrieval services, integrated online library support software, and communication and networking standards. A description is provided of a prototype system that would combine a gateway capability with a locally managed facility to meet a library's total needs. (EM)

Online information services (e.g., DIALOG, ORBIT) and computer databases (e.g., Social Sciences Citation Index, Historical Abstracts) that historians can use in their historical research are discussed. The important differences among representative databases are described. (RM)

Presents data model based on text data model (TDM), universal relation model, and nonfirst normal form (NFNF) relations, and discusses applicability to text processing and document retrieval systems. Highlights include database technology applied to information retrieval, NFNF and universal relation, and TDM integration with NFNF universal…
