Representatives from three companies (Management Contents, ABI/INFORM, Predicasts) explain the coverage, content, thesauri, updating, products, and capabilities of their data bases. A panel of librarians from (1) a special library, (2) an academic library, and (3) a public library report on the use of business data bases in their respective…

The technique for machine-aided indexing developed at the Defense Documentation Center (DDC) is illustrated on a randomly chosen abstract. Additional text is provided in coded form so that the reader can more fully explore this technique. (2 references) (Author)

Describes the automatic indexing project undertaken in 1978 to convert by means of a "bridge vocabulary" the terms in the ABI/INFORM database to index terms of a controlled vocabulary. Components of the bridge vocabulary are explained, and examples demonstrating the process of conversion are provided. (JD)

Describes a framework for building "story traces" (compact global views of a narrative) and "story projects" (selections of key elements of a narrative) and their applications in text understanding and classification. The resulting "abstract story traces" provide a compact view of the underlying narrative's key…

A definition of fiber art, its history, materials and techniques, vocabularies, and creators and users of those vocabularies offer background for understanding the problems in preparing surrogates of this relatively recent art form for text and image databases. Four examples of fiber image information systems are described. (32 references) (EAM)

Investigated how health educators could improve literature searches and increase the accessibility of their research to others. A frequency count of databases indexed 84 health education journals and analyzed the 16 top indexes for journal coverage. Results indicated that selecting the appropriate indexes can help health educators more effectively…

Describes a clustering algorithm designed for dynamic data bases and presents an update procedure which maintains an effective document classification without reclustering. The effectiveness of the algorithms is demonstrated for a subset of the Cranfield collection. (Author)

A comparison of ERIC and LISA (Library and Information Science Abstracts) indexing of the three journals--Online, Online Review, and Database--revealed some differences but more similarities in number of terms per article and concepts per article. A vocabulary which distinguished the field of online searching did emerge. (Author/EM)

Holds that database producers and online system vendors have failed to maintain sufficient quality control over their products, and that online searchers should voice their complaints about file documentation errors, indexing inconsistencies, and incorrect data entries. (FM)

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…

Focuses on the growth of the United Kingdom company Ingenta in the United States. Highlights include a new partnership with Gale Group related to their InfoTrac databases; indexing and full text coverage; standards; and other Ingenta acquisitions. (LRW)

Proposes a fuzzy-image database model and a concept of fuzzy space; describes fuzzy-query processing in fuzzy space and fuzzy indexing on complete fuzzy vectors; and uses an example image database, the computer-aided facial-image inference and retrieval system (CAFIIR), for explanation throughout. (Author/LRW)

This brief review of the Educational Resources Information Center (ERIC) system is intended to make users more aware of (1) the system as a whole, (2) the process of indexing educational literature for the database, and (3) the role of the Thesaurus of ERIC Descriptors in the overall information dissemination process. An overview of the ERIC…

The development of the INSPEC vocabulary system which comprises a unified indexing and classification scheme is described together with the reasons for its adoption. (Author)
