Investigates problems of using commercial search engines for Web-based research. Findings indicate that search engines are highly variable in their results, are limited in the search functions they offer, have poorly and/or incorrectly documented functions, use search logics that are opaque, and change search functions they offer over time.…

This review of the evolution of the Dewey Decimal Classification over past 30 years concentrates on three conflicts that have influenced recent developments: integrity of numbers versus keeping pace with knowledge; detailed bibliographic classification versus shelf location device; and national bias versus internationalization. Seven references…

Discussion of document ranking methods to calculate the conceptual distance between a Boolean query and a document focuses on the Knowledge-Based Extension Boolean Model which evaluates weighted queries and documents effectively and avoids problems of previous methods. Semantic networks are discussed, and is-a hierarchies are explained. (21…

Discusses evidence-based decision making; describes techniques to support evidence-based retrieval in the field of medicine which emphasize the retrieval and application of high quality knowledge to solve real-world problems; and considers the transferability of evidence-based information seeking to other fields. (Contains 69 references.) (LRW)

Describes features of Bliss Bibliographic Classification (BC2) that make it thesaurus-compatible and a source for thesaurus compilers: facet analysis, terminology source, thesaural relationship source, and updating ease. Problems with using BC2 as a thesaurus source are also considered, and two thesauri based on BC2 are described. (MBR)

Reviews problems identified in previous research on evidence-based nursing practice; discusses conflicts between medical and nursing domains; explores the provenance and status of the clinical guideline as a translation artefact or bridging mechanism based on a social studies of science approach; and presents a case study of Scottish clinical…

Introduces the application of informetric methods to the World Wide Web (Webometrics). Presents a case study comparing the number of specific informetric analysis parameters of Denmark, Sweden, and Norway on the Web. Concludes that problems with data collection occur because current tools are inadequate and because collection methods, manual and…

Discusses statistical analyses of the effect of reduction in opening hours on book issues, or borrowing, of public library authorities (PLAs) in the United Kingdom. Demonstrates the difficulties involved in using statistical data to make accurate predictions of the impact of opening hour reductions on borrowing. (Author/LRW)

Discussion of the causes of communication problems between physicians and chronically ill patients focuses on the information-seeking patterns of women with multiple sclerosis (MS). A survey investigated whether a woman's general orientation to information or the length of time she had MS affected her choice of information resource. (Author/LRW)

Explains the efforts of the ICSTI (International Council for Scientific and Technical Information) Group on Interdisciplinary Searching to identify and describe problems of interdisciplinary searching and to propose solutions. Problems are summarized in six areas: database coverage and technical content, bibliographic information, textual content,…

Presents a survey of the current state of documentation practice in museums, concentrating on the broad themes of the practice, and making comparisons with analogous library procedures where appropriate. Current developments on an international and national scale (18 countries) are reviewed, and a 326-item bibliography is included. (Author/JD)

Examines the concepts involved in user studies, information needs, and information seeking behavior to propose a basis and direction for future research in information science. Twenty-eight references are listed. (RAA)

Proposes an argumentation-based method for information retrieval that involves representing a scholarly article by means of rhetorical structure rather than by a semantic representation of content. Topics addressed include problems with indexing practices, the argumentative nature of articles, rhetoric as an information categorizing schema, and…

Discusses information retrieval techniques involving both Boolean retrieval schemes and a weighting mechanism to produce ranked search output and points out theoretical ambiguities and inconsistencies demonstrated by recent research. An alternative search approach is outlined and analyzed and a more rigorous methodology is suggested. Eleven…

Discusses the special information needs of the building industry, attributes of existing expert systems that support building design and construction, and current research to further develop the application of expert systems to this area. An annotated listing of related expert system developments is appended. (49 references) (CLB)
