Bosc, P.; Lietard, L.; Pivert, O. – Information Processing & Management, 2003
Considers flexible querying of relational databases. Highlights include SQL languages and basic aggregate operators; Sugeno's fuzzy integral; evaluation examples; and how and under what conditions other aggregate functions could be applied to fuzzy sets in a flexible query. (Author/LRW)
Descriptors: Databases, Evaluation Methods

Stejic, Zoran; Takama, Yasufumi; Hirota, Kaoru – Information Processing & Management, 2003
Proposes local similarity pattern (LSP) as a new method for computing digital image similarity. Topics include optimizing similarity computation based on genetic algorithm; relevance feedback; and an evaluation of LSP on five databases that showed an increase in retrieval precision over other methods for computing image similarity. (Author/LRW)

Mowshowitz, Abbe; Kawaguchi, Akira – Information Processing & Management, 2002
Addresses the measurement of bias in search engines on the Web, defining bias as the balance and representation of items in a collection retrieved from a database for a set of queries. Assesses bias by measuring the deviation from the ideal of the distribution produced by a particular search engine. (Author/LRW)

Chignell, Mark H.; Golovchinsky, Gene – Information Processing & Management, 1997
Discusses similarities between newspapers and hypertext databases; describes VOIR (Visualization of Information Retrieval), a software prototype used as an electronic newspaper workbench; presents results of empirical evaluation; and suggests implications for hypertext and information retrieval. (Author/LRW)

White, Howard D. – Information Processing & Management, 2001
Presents a methodology for educators to assess coverage, overlaps, and gaps in their curricula, of validating their present course offerings, and of monitoring subject-matter trends by using descriptors from commercial bibliographic databases. Describes a study that modeled the curricula for Drexel University's College of Information Science and…

Kocberber, Seyit; Can, Fazli – Information Processing & Management, 1997
Discussion of data storage technology for multimedia materials highlights a new signature file method that divides files into variable-sized vertical frames to optimize response time using partial query evaluation. Real data experiments that tested the response time are reported, and future work is discussed. (Author/LRW)

Savoy, Jacques – Information Processing & Management, 2003
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…

Rada, Roy; And Others – Information Processing & Management, 1996
Discusses management of a research group and examines the role of collaborative hypertext in supporting the maintenance of a hypertext database about hypotheses and research papers. Highlights include hypothesis formulation; paper revision, including appropriate journal selection and author collaboration; information technology support; and an…

Wildemuth, Barbara M.; Friedman, Charles P.; Keyes, John; Downs, Stephen M. – Information Processing & Management, 2000
Examines the effects of database assistance on clinical problem solving across three cohorts of medical students and two database interfaces. Discusses the relationship between personal domain knowledge and problem solving, personal domain knowledge and database searching, and comparisons of different interface styles in information retrieval…

Mehtre, Babu M.; And Others – Information Processing & Management, 1997
Explores the evaluation of image and multimedia information-retrieval systems, particularly the effectiveness of several shape measures for content-based retrieval of similar images. Shape feature measures, or vectors, are computed automatically and can either be used for retrieval or stored in the database for future queries. (57 references)…

Sumner, Robert G., Jr. – Information Processing & Management, 1995
The effectiveness of using the age of references to control the exhaustivity of the reference representation in information retrieval was investigated through analysis of optimal cluster-based retrieval results. The results show that the foreground representation at its optimal level of exhaustivity is restricted to references with ages less than…

Oakes, Michael P.; Taylor, Malcolm J. – Information Processing & Management, 1998
Reports on the design of an automated query system to help pharmacologists access the Derwent Drug File (DDF). Topics include knowledge types; knowledge representation; role of the search intermediary; vocabulary selection, thesaurus, and user input in natural language; browsing; evaluation methods; and search statement generation for the World…
