Suggests ways to increase precision when searching full text files on BRS, Mead Data Central and DIALOG. All of the techniques are based on achieving repetition of central concepts as expressed in natural language. Schematic representations of strategies and sample searches on each of the three systems are provided. (10 references) (CLB)

Applies a prefix trie index, or trie hashing, to the problem of providing fast search times, fast load times, and fast update properties in a bibliographic or full-text retrieval system with inverted files. Statistics are given for a test database consisting of an online catalog at the University of Western Ontario. (Author/LRW)

Describes some of the problems encountered in full text searching and suggests ways to overcome them. Areas discussed include differences between online and offline versions of full text; lack of precise and flexible indexing; software inadequacies; record displays; typographical errors; and problems with both global and source searching. (six…

Describes the training and support offered to users upon the implementation of a corporate online text retrieval system, and offers insights from the experience. Areas discussed include training programs and objectives, user support services and support personnel, user documentation, database building, and performance evaluation and measurement.…

Provides a chronology of news library automation and describes the current functions and services of a newspaper library. Areas discussed include clerical tasks, automated clip files, the use of free text searching and field specificity in newspaper databases, the development of online experts, and the impact on the skills required of news…

This paper describes online newsmedia databases which have been intentionally designed to respond to needs for information that is more current than the information in printed indexes or online versions of these indexes. It is suggested that these databases are useful to libraries because, in addition to subject indexing, they have "word…

Discusses the role of end users in the design of a multi-format digital library project, ISLA (name derived from Spanish word for "island"), being developed at the University of Southern California library for the study of the Los Angeles region. Topics include spatial and temporal indexing; the geographic information system element;…

Describes the InfoTrac SearchBank based on experiences at the University of Nevada, Reno, libraries where the service is available through the online catalog. Highlights include remote access through the Internet; indexing and abstracting; full-text access to 460 journal titles; a powerful search engine; and business-oriented databases.…

Addresses problems with automated bibliographic and full-text storage of scientific articles. The role of the scientific article is described, the structure is explained, current indexing and information retrieval techniques are criticized, new possibilities using a rhetoric syntax or argumentational syntax are explored, and the use of hypertext…

Describes a study that compared two information retrieval systems on a full-text medical database: one featured concept-based automatic indexing and statistical retrieval techniques, and the second used traditional word-based Boolean techniques. Evaluation of search results by calculating relative recall and precision is discussed, and user…

Presents abstracts of 36 special interest group (SIG) sessions. Highlights include the Chemistry Online Retrieval Experiment; organizing and retrieving images; intelligent information retrieval using natural language processing; interdisciplinarity; libraries as publishers; indexing hypermedia; cognitive aspects of classification; computer-aided…
