Presents a prototype system for image retrieval from the Internet using Web mining. Discusses the architecture of the Web image retrieval prototype; document space modeling; user log mining; and image retrieval experiments to evaluate the proposed system. (AEF)

Explores what might be the optimal query expansion (QE) processing method with semantically coded thesauri. Examines whether QE via semantically coded thesauri terminology is more effective in the "automatic" or "interactive" processing environment. Results revealed that synonyms and partial synonyms and narrower terms are…

Describes creation of a relational database at the University of Washington supporting ongoing academic planning at several levels and affecting the culture of decision making. Addresses getting started; sharing the database; questions, worries, and issues; improving access to high-demand courses; the advising function; management of instructional…

Discusses improving the quality of satisfaction of information needs through the use of information retrieval systems. The characteristics of information need are investigated; a new instrument in information retrieval systems is proposed which takes into account different components of information need; and future research is suggested.…

Urges chief information officers (CIOs) at colleges and universities to be not only information systems representatives to the executive team, but full-spectrum contributors to the institution's business strategies and directions. Considers the CIO's role in politics and public relations, finance, marketing, in relation to the chief executive…

Asserting that there is tremendous value to higher education institutions that develop initiatives to share knowledge to achieve business objectives, this article outlines the basic concepts of knowledge management as it is applied in the corporate sector, considers trends, and explores how it might be applied in higher education and whether…

Describes how experts create and use "bundles"--organized, highly selective collections of information--to help solve problems and maintain situation awareness. Based on fieldwork in an intensive care unit, five examples of bundles are described that illustrate the variety of bundles in use. A summary of bundle properties is given. (AEF)

Information retrieval (IR) is driven by a process that decides whether a document is about a query. The purpose of this article is to consider "aboutness" from a fundamental, neutral perspective, to shed light on the nature of aboutness by formalizing properties describing it, and to define a set of reasonable properties of aboutness,…

An upstate New York district became a pilot site for a technology industry initiative to build software systems that eliminate traditional interdepartmental barriers. This article describes interactive software systems (especially the Schools Interoperability Framework) that can transform a district's administrative tasks into a free-flowing,…

Traditional themes of information science must be expanded to accommodate systematic understandings of ways to design effective documentary systems and anticipate their social consequences. The field of social informatics offers important concepts, theories, and methods that give this kind of inquiry a sound scientific basis. Social informatics…

Introduces a hybrid method for abstracting Chinese text that integrates the statistical approach with language understandings, incorporating some linguistics heuristics and segmentation into the abstracting process. Initial responses from application to Chinese newspaper articles show that the method contributes much to the flexibility and…

Experimental results show that a word-based arithmetic-coding scheme, a fractional-bit compression algorithm which is known to be time consuming, can achieve a higher compression performance for Chinese text. This article examines how to cascade the word-segmentation model with a faster alternative, the integral-bit compression algorithm.…

Prompted by the "millennium bug," many school districts are in the process of replacing non-Y2K-compliant information systems. Planners should establish a committee to develop performance criteria and select the winning proposal, estimate time requirements, and schedule retraining during low-activity periods. (MLH)

Provides an introduction to articles in this special "Perspectives" issue of "Journal of the American Society for Information Science and Technology." The articles, taken collectively, contain significant elements of a research agenda in image indexing and retrieval for the next decade. Articles focus on user, representation,…

The effects of long-term hospitalizations can be severe, especially among older adults. In Manitoba, between fiscal years 1991/1992 and 1999/2000, 40 per cent of acute care hospital days were used by the 5 per cent of patients who had long stays, defined as stays of more than 30 days. These proportions were remarkably stable, despite major changes…
