Describes the design and implementation of a prototype visualization system, AuthorLink, to enhance author searching. AuthorLink is based on author co-citation analysis and visualization mapping algorithms. AuthorLink produces interactive author maps in real time from a database of 1.26 million records supplied by the Institute for Scientific…

Discusses cross-language, multilingual, and bilingual information retrieval on the Web; evaluates retrieval effectiveness of indexing and search strategies based on test collections from CLEF (Cross-Language Evaluation Forum) in English, French, German, and Italian; and suggests and evaluates database merging strategies. Appendices include…

Explains the objective of the ARL (Association of Research Libraries) Scholars Portal initiative as the development of scholarly productivity tools and services. Considers the library's role and describes the initial emphasis on developing a tool that delivers licensed and openly available digital content across a range of subject fields and from…

Describes the visualization of a navigation classification scheme in an information retrieval (IR) system. Highlights include Charles Cutter's rules for creating a dictionary catalog; user needs; an example of undergraduate research using this scheme; and user interaction with the IR system. (Contains 64 references.) (Author/LRW)

Studied users' queries for visual information in American history to identify the image attributes important for retrieval and the characteristics of users' queries for digital images, based on queries from 38 faculty and graduate students. Results of pre- and post-test questionnaires and interviews suggest principle categories of search terms.…

Explores the relationship between the concept of uncertainty in information seeking within a model of the problem-solving process and variables derived from other models, based on longitudinal data collected in the United Sates and the United Kingdom that investigated the processes of mediated information retrieval searching during human…

Discusses research traditions in education and in information retrieval and explores the theory of expected information which uses formulas derived from the Fano measure and Bayesian statistics. Demonstrates its application in a study on the effects of concept mapping on the search behavior of tenth-grade biology students. (Author/LRW)

Discusses the role of intelligent agents in facilitating the seeking and retrieval of information in Web-based library environments. Highlights include an overview of agents; current applications in library domains; an agent-based model for libraries; the design of interface agents; and implications for library policy and digital collections.…

Discussion of searching for information on the Web focuses on resources that are not always found by traditional Web searches. Describes sources on the hidden Web, including full-text databases, clearinghouses, digital libraries, and learning objects; explains how search engines operate; and suggests that traditional print sources are still…

Describes the development of a software system, SIMPR (Structured Information Management: Processing and Retrieval), that will process documents by indexing them and classifying their subjects. Topics discussed include information storage and retrieval, file inversion techniques, modelling the user, natural language searching, automatic indexing,…

Describes ArchiVISTA, an optical disk image retrieval system that provides access to cartoons and caricatures in the National Archives of Canada. Planning, evaluation, design and image capture, and retrieval are explained, as well as how the system developed from earlier efforts of bibliographic control and imaging technology. (10 references) (EAM)

Compares "Library Literature" with "Library and Information Science Abstracts" (LISA) and outlines searching LISA on the SilverPlatter CD-ROM. Use of indexes and abstracts to aid information retrieval is explained; abstracting services are described; and five steps in writing an abstract are listed. Abstracts and annotations…

Reviews the implementation of an experimental project in the Pan American Health Organization to disseminate health related information via CD-ROM in Latin America and the Caribbean, and compares the costs and relative advantages of information delivery using online retrieval systems and CD-ROM systems in developing countries. (four references)…

Discusses the need for a rich semantics for the user interface in interactive image retrieval and presents two methods for building such interfaces: possibility theory applied to fuzzy data retrieval, and a machine learning technique applied to learning the user's deep need. Prototypes developed using videodisks and knowledge-based software are…

Evaluates four map products currently available on CD-ROM in terms of hardware requirements, ease of installation, software, product content, documentation, cost, and instructional materials. Conclusions about the current status of maps on CD-ROM are offered and the desired characteristics for a perfect CD-ROM mapping product are identified. An…
