Discusses changes in the location and provision of information services that have resulted from online technologies, particularly the World Wide Web. Highlights include knowledge management in digital libraries; the importance of research on information technology and digital libraries; semantic indexes; concept switching; information analysis;…

Investigates information retrieval from hypertext on the World Wide Web. Significant main and interaction effects were found for both link density (number of links per display) and display format (paragraphs or lists) on search performance. Low link densities displayed in list format produced the best overall results. Expert browsers performed…

Evaluates Japanese journals--128 indexed in the 1994 "Journal Citation Reports"--in bibliometric parameters such as impact factors (IFs), mean IFs from citing and cited journals, and self-citing and self-cited rates. Results: only 15 journals, with a wide variation of self-citing and self-cited rates, have obtained a current impact…

Content-based image retrieval is based on the idea of extracting visual features from images and using them to index images in a database. Proposes similarity measures and an indexing algorithm based on information theory that permits an image to be represented as a single number. When used in conjunction with vectors, this method displays…

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…

Provides an overview of the professional work of Irving Sher. Highlights include his role in the development and implementation of Science Citation Index; the development of the first selective dissemination of information system; development of the journal impact factor; a system of coding references; and citation-based historiography. (LRW)

Reviews research on how people use mental models of images in information retrieval. Discusses cognitive and social processes that give rise the visual models shaped by indexers and searchers. Examines the representation of objects and shapes in visual mental models and how both content-based and concept-based indexes capture aspects of these…

Fit indexes were compared with respect to a specific type of model misspecification. Simple structure was violated with some secondary loadings that were present in the true models that were not specified in the estimated models. The c2 test, Comparative Fit Index, Goodness-of-Fit Index, Incremental Fit Index, Nonnormed Fit Index, root mean…

Smith's article "On Construct Validity: Issues of Method and Measurement" is a fine tribute to L. J. Cronbach and P. E. Meehl (1955) that clarifies the current state and future directions in the understanding of construct validity. Construct validity is a dynamic process, and fit indices need to be used at the service of understanding, not in…

Educational measurement practitioners are often asked to link scores on tests that are built to different content specifications. The goal in linking distinct tests is often similar to that for equating scores across different forms of the same test: to provide a set of comparable scores across the two measures. Traditional equating methods can be…

This article reports on methodological approaches to evaluate the relevance and quality of educational research publications. In the first section it focuses on the ISI Social Science Citation Index and shows that this standard instrument for bibliometric measurement is insufficient for the representation of European educational research. In the…

This article estimates the standard demand equations for nonresident students using national, state, and institutional level data. The national-level analysis reveals a near-unitary price elasticity, but increases in nonresident tuition and fees do not decrease nonresident enrollment. Finally, results from the institutional level of analysis…

The semantic web or Web 3.0 makes information more meaningful to people by making it more understandable to machines. In this article, the author examines the implications of Web 3.0 for education. The author considers three areas of impact: knowledge construction, personal learning network maintenance, and personal educational administration.…

Describes the implementation and first year's operation of the online end-user bibliographic data service created for United Kingdom academic libraries, the Bath Information Data System (BIDS ISI), which was created in cooperation with the Institute for Scientific Information. Assesses its impact on the activities of computer centers, libraries,…

This videography of African-related films was developed over several years. The project arose as a response to the requests by school districts, community and small colleges, and universities for a source of recent videos for rent or purchase. Three hundred twenty-one (321) African-content video titles are listed by distributor. Each citation…
