Strategies, heuristics, and tradeoffs involved in online searching of bibliographic citation networks are discussed using results from field of citation analysis to describe mathematical structure of citation networks. Discussion of two studies of human information seeking behavior examines the search question and interconnectivity of the…

Discussion of library information systems focuses on the idea of including user-supplied data (USD) in libraries' automated catalogs. Hypertext is mentioned, the information explosion and the ability to selectively retrieve information is considered, and the value of user input in evaluating the relevance of material is discussed. (12 references)…

A factor analysis of affective data gathered from searchers of an online library catalog, and a card catalog allowed researchers to isolate factors leading to success or failure in information retrieval. Factor patterns serve to identify how searches are evaluated by users. Further research is suggested as are features to facilitate successful…

Describes a study of users' document selection behavior that was conducted to build a tentative cognitive model of document selection behavior to be used in designing intelligent information retrieval systems. Topics addressed include studies of relevance and of decision making; value judgments; and document information elements considered during…

Discusses individual differences between users of information systems that can influence search performance, and describes two experiments that addressed user-centered design of information systems. Highlights include interaction between cognitive abilities and design features; compensation and capitalization perspectives; recall and precision;…

Proposes an operational definition of relevance for a Web-based library catalog. Proposes measures that characterize user behavior while searching a Web-based library catalog. Develops a methodology to predict when a user's search will be perceived to be relevant by the user. Tests the methodology with over 900,000 user search sessions with the…

Proposes a useful concept of relevance as a relationship and an effect on the movement of a user through the iterative stages of their information seeking process, and that users' relevance judgments can be plotted on a Three-Dimensional Spatial Model of Relevance Level, Degree and Time. Discusses implications for the development of information…

Illustrates how various key abstractions of information finding, such as document relevance, a desired number of relevant documents, discouragement, exhaustion, and satisfaction can be modeled using the Petri Net framework. Shows that this model leads naturally to a new approach to collection of user data, and to analysis of transaction logs.…

This thesaurus was designed for users of the Adult and Continuing Education Research Collection in Syracuse University (New York), which contains the archives of organizations and individuals central to the development of adult education as a field of study and practice. The thesaurus serves the historical and archival adult education materials of…

This paper presents an overview of the major Canadian online systems, which account for approximately 5% of information vendors and databases worldwide. Also described is DATAPAC, Canada's national telecommunications network, and DATAPAC's X.75 interface with TELENET, TYMNET, UNINET, and France's TRANSPAC. The online systems described include: (1)…

This paper considers the interface between an elementary school child and a computerized fact retrieval system. The goals of the study were to transfer the communication burden from the user of a computerized system and to investigate the effect of such a system on education. (Author/HB)

A mechanized current awareness service based on an in-house created bibliographic data base which is provided to Congress and to researchers at the Library of Congress is described. (Author)

This is a bibliography of documents published from 1983 to December 1987 on the National Assessment of Educational Progress (NAEP) contained in the database of the Educational Resources Information Center (ERIC). The extensive literature is organized into a compendium of 244 abstracts of research relating to NAEP to make a useful tool for other…

This is a guide to databases and computerized search services in the field of bilingual education. The first section of the guide lists 37 computerized databases which can be searched online to locate bibliographic, statistical, legislative, and other information about bilingual education and about other subject areas related to the education of…
