Introduction: This study investigated the effect of cognitive styles on users' information-seeking task performance using a knowledge domain information visualization system called CiteSpace. Method: Sixteen graduate students participated in a user experiment. Each completed an extended cognitive style analysis wholistic-analytic test (the…

An "answer-passage" is a passage which is either answer-providing or "answer indicative." New text searching techniques for the retrieval of answer-passages are discussed. Appendices listing thesauri, glossaries and dictionaries, syntactic joints, and connector words are included. (31 references) (Author/RS)

A series of five batches of twenty searches were carried out in a three year span of the INSPEC data base by the 31 Company's Information Retrieval Service. The same queries were processed manually in the corresponding volumes of Science Abstracts and comparison of the output of each search method exposed reasons for the failures. Emphasis is laid…

The purpose of the investigation was to determine how effectively biomedical practitioners, with a minimum of introduction to the system, can conduct on-line searches to satisfy their own information needs. The searches were conducted on the Abridged Index Medicus data base as implemented on the on-line ELHILL system (AIM-TWX). ELHILL is the ORBIT…

The Educational Resources Information Center (ERIC) system's computerized data base was the focus of a three-hour tutorial session on search strategies. This document is the workshop manual used by the tutorial participants. The discussion of the input phase of a computer search covers identification of the user population, receiving the inquiry,…

This book is designed primarily to help users find meaningful words for natural language, or free-text, computer searching of bibliographic and textual databases in the social and behavioral sciences. Additionally, it covers many socially relevant and technical topics not covered by the usual literary thesaurus, therefore it may also be useful for…

This book deals with properties of vocabularies for indexing and searching document collections; the construction, organization, display, and maintenance of these vocabularies; and the vocabulary as a factor affecting the performance of retrieval systems. Most of the text is concerned with vocabularies for post-coordinate retrieval systems, with…

This report provides a brief general summary of progress in a 2-year project renewing earlier work on the development of Individualized Instruction for Data Access (IIDA)--a system for teaching online searching techniques for bibliographic data bases--as well as an in-depth report on the IIDA computer system design. The Connector for Networked…

This report describes the development of a design and a small working model for a system for teaching and assisting in the performance of bibliographic on-line searches through the use of an intermediary computer. The system in its present form is intended for direct users of scientific and technical information systems. However, it is felt that…

Statistics gathered over five years of operation by the IIT Research Institute's Computer Search Center are summarized for profile terms and lists, use of truncation modes, use of logic operators, some characteristics of CA Condensates, etc. (Author/JB)

The operations of the New England Research Application Center's IBM 1130 are described and the problems of using it for chemical information retrieval are discussed. (Author/JB)

Retrospective search of large data bases requires development of special techniques for automatic compression of data and minimization of the number of input-output operations to the computer files. The computer program should require a relatively small amount of internal memory. This paper describes the structure of such a program. (9 references)…

Step-by-step instructions for locating material in the Educational Resources Information Center (ERIC) database are provided. Following an introduction, information is presented in three main sections--manual searching, computer searching, and using search results. Subdivisions under manual searching describe who can or should do a manual search…
