Discussion of self-report estimates of frequency and duration of computer use versus computer log data focuses on a study that compared self-report estimates and six months of electronic log data for health care workers using a new Community Services Information System. Correlations between the two types of data are reported. (Author/LRW)

Describes the work of rural-circuit medical librarians and explains the development of mapping techniques and information systems they use, based on an oral history. Discusses the use of oral history as a research method; cultural landscaping and mapping; and maps as cultural artifacts. (LRW)

Reports on an empirical study that investigated the use of hypertext information systems during architectural design problem solving. Discusses theoretical notions on design problem solving, changing informational needs, and educational implications related to learning in complex domains. (Author/LRW)

Describes the use of geographic information systems (GIS) by a "local learning team" to map socioeconomic patterns in Jackson County, Kentucky, and to evaluate the distribution of local funding and the geographic equity of representation related to the Empowerment Zone/Enterprise Community program. Discusses advantages and disadvantages…

Uses Kintsch's proposition-based construction-integration theory of discourse comprehension to detail the user coding operations that occur in each of the three subsystems (Perception, Comprehension, Application) in which users process an information retrieval systems (IRS) message. Describes an IRS device made up of two separate parts that enable…

An n-gram is a string of characters, usually adjacent, extracted from a section of continuous text that can be used in spelling error detection and correction, query expansion, information retrieval, dictionary search, text compression, and language identification applications. This article provides an introduction to the use of n-grams in textual…

Presents a heuristic, attribute-based, noise-tolerant data mining program, HCV (Version 2.0) based on the newly-developed extension matrix approach. Outlines some techniques implemented in the HCV program for noise handling and discretization of continuous domains; an empirical comparison shows that rules generated by HCV are more compact than the…

Explains that a corporate Web application is a corporate information system that uses World Wide Web technology to provide access to a variety of corporate information resources for internal and external users in geographically distributed locations. Top-down development is explained, and design requirements are discussed. (Author/LRW)

Considers the need for specialization in library and information science education as opposed to a more generalized entry degree, and presents two case studies to further discuss the issue, one in archival science and one in information systems and technology. Convergence and divergence is also discussed. (LRW)

In one study, reading comprehension data for 62, 739 students from an Accelerated Reader learning information system was merged with the Tennessee Value-Added Assessment System (TVAAS) teacher-effects database. Results show that teachers should have students read as much as possible, gradually increasing books' challenge level. (Contains 115…

This case study, of an application to facilitate dispatch work in a large organization, describes a history of collaboration and conflict between information systems professionals and end users as system designers. A Social Construction of Technology approach is used to examine the mixture of cooperation and conflict between the departments.…

This research is concerned with reusing texts produced by audio describers as a source for automatically deriving shot-level indexing for film and video products. Results reinforce the notion that audio description is not sufficient on its own as a source for generating an index to the image, but it is valuable because it describes what is going…

Presents an abstract for a planned session on the need to coordinate user studies and information retrieval system design research. Topics include human-based research and system-based research; children's information use; usability and cartographic information systems; and ethnomethodology and system design. Panelists included: Nick Belkin, Dania…

Examines reasons that prompted the current shift from information to knowledge processing, encompassing both social contextualization and the recent technological advance. Discusses knowledge production, viewed as a five-step process. The highly interdisciplinary perspective and the primacy of the user are distinguished as necessary prerequisites…
