This research reports an algorithmic approach to the automatic generation of thesauri for electronic community systems. The techniques used include term filtering, automatic indexing, and cluster analysis. The Worm Community System, used by molecular biologists studying the nematode worm C. elegans, was used as the testbed for this research.…

Performance is a critical factor hindering the use of object-oriented databases (OODB). This article proposes a new and uniform indexing scheme for enhancing OODBs with advantages for small range, clustered sets queries. Reviews several other indexing schemes; presents the U-index scheme; discusses its performance; and presents experimental…

Describes the design and implementation of a system for computer generation of linked HTML (Hypertext Markup Language) documents to support information retrieval and hypertext applications on the World Wide Web by adding an interactive indexing technique that is compatible with Web browsers. (Author/LRW)

Identifies and describes methods of compiling datasets, search interfaces and etymological metaphors and mythologies of three of the first generation of automated indexing systems: archie, veronica, and robots and search engines. (Author/JKP)

Describes the development of Java-based software to use controlled vocabularies and subject headings in the cataloging of Web-based HTML articles on a subject-specific legal resources Web site. Topics include requirements for cataloging and for searching; data structure; software required; and metadata with Dublin Core requirements. (LRW)

This paper presents some of the efforts currently being made to develop mechanisms that can organize World Wide Web resources for efficient and effective retrieval, as well as programs that can accommodate multiple languages. Part 1 discusses structural approaches to organizing Web resources, including the use of hierarchical or…

This issue presents 11 articles that address issues relating to the production of CD-ROMs. Highlights include current uses of CD-ROM; standards; steps involved in producing CD-ROMs, including data capture, conversion, and tagging, product design, and indexing; authoring; selecting indexing and retrieval software; costs; multimedia CD-ROMs; and…

Discussion of the development of multimedia courseware for medical education focuses on repurposing or reusing data from multiple sources. Issues addressed include designing courseware with repurposing in mind; the format of the content and the intended microcomputer format; and content indexing for storage and retrieval. (18 references) (LRW)

Explores the intellectual subject structure and research themes in software engineering through the identification and analysis of a core journal literature via two expert perspectives: the author, through cocitation analysis; and the indexer, through subject terms selected to facilitate retrieval. Topics include cluster analysis, multidimensional…

Discusses cataloging and indexing for the retrieval of digital items as part of the British Library's Initiatives for Access program. Highlights include standards, digital catalogs, Novel access software that includes fuzzy matching, software choice and development, and future possibilities. (LRW)

Discusses various aspects of multimedia instruction, including differences in goals from those of computer-assisted instruction; guidelines for the successful use of interactive multimedia instruction; the use of multimedia lessons in an introductory chemistry course; applications of multimedia instruction for indexing, hypermedia, simulations,…

Discussion of the use of case-based teaching methodologies highlights the development of four case-based software programs: (1) VICTOR, a voice and image courtesy tutor; (2) DUSTIN, a language training system for non-English speaking employees; (3) CREANIMATE, a biology tutor for students; and (4) TAXOPS, a tax opportunity advisor. (Contains 27…

Discusses intelligent filtering systems and describes work in the INFOS (Intelligent News Filtering Organizational System) project designed to automatically categorize data as relevant or irrelevant based on user interests. The filtering is performed by combining keyword-based hill climbing, knowledge-based conceptual representation via WordNet,…

This study of an online search strategy based on word frequency found that it provided 98% sensitivity in retrieving systematic reviews of health-care interventions in MEDLINE, while retaining a low (20%) but acceptable precision. Presents other strategies with other levels of sensitivity and precision and discusses factors that may affect the…

Describes experiments in Arabic information retrieval using 29 queries against a base of 355 bibliographic records. Using roots and stems as index terms worked better than words, and the root performed as well as or better than the stem at low recall levels and definitely better at high recall levels. (Contains 30 references.) (KRN)
