Integrates structured data and text using the unchanged, standard relational model. The performance of a parallel relational database system and the effect of query reduction on accuracy were tested, and it was found that queries can be reduced prior to their implementation without incurring significant loss in precision/recall.

Attempts to persuade friends and colleagues in the computers and writing community to do more to ensure that the Web pages (especially for classes) are accessible to people with disabilities. Raises this issue as a matter of some urgency in light of the surging interest in multimedia and visual rhetoric represented by this special issue. (SG)

A planning committee needed to create a plan for the infusion of technology in all areas of a school district. Decisions included standardization of hardware, network, and wiring. Four figures and text illustrate a network computer and printer in each classroom, a wide area network, and a voice and video network. Offers key suggestions for…

Responds to Closs' (1994) article concerning the project management concerns of the UK PROSPECT system. Suggests that the problems encountered in the implementation of UK PROSPECT were not caused by project management, but were, as suggested by Watts (1993), economic and political in nature. (JPS)

Describes a simulated student that learns by interacting with a human tutor. Tests suggest that simulated students, when developed past the prototype stage, could be valuable for training human tutors. Provides a computational cognitive task analysis of the skill of learning from a tutor that is useful for designing intelligent tutoring systems.…

Explores the possibility of considering the creation and maintenance of reference librarians' personal Web sites as part of their professional duties. Reviews a sample of personal Web sites and the results of an e-mail survey targeting such sites and their creators. Examines three home pages to provide more detailed information about site…

Considers the problem of improving the performance of Web access by proposing a reconstruction of the internal link structure of a Web site to match quality of the pages with popularity of the pages. Provides a set of simple algorithms for local reorganization of a Web site, which results in improving users' access to quality pages in an easy and…

Describes the Performance-Centered Design (PCD) approach that tackles the usability dilemma of computer systems. Discusses PCD success factors; characteristics of adult learning incorporated into PCD methodology; PCD design techniques; interface requirements; and benefits of the PCD methodology. (AEF)

Describes SIVAS, a computer-based system for driver education based on visual simulation that was developed in Spain to support theoretical concepts about driving in driving schools. Explains how teachers can select pre-built scenarios related to driving lessons in order to make up a lecture. (Author/LRW)

Suggests that known sources of name variation and error in information systems must be addressed through improved retrieval techniques. Argues that a culture of data stewardship in which fewer errors are introduced in the handling of personal names can be achieved through greater awareness of problems specific to handling of names, and the design…

Reports on an Open University evaluation study of the Informedia Digital Video Library System developed at Carnegie Mellon University (CMU). Findings indicate that there is definite potential for using the system, provided that certain modifications can be made. Results also confirm findings of the Informedia team at CMU that the content of video…

Reviews problems with the World Wide Web that can be attributed to human error or ineptitude, and provides suggestions for improvement. Discusses poor Web design, poor use of search engines, and poor quality control by search engines and directories. (AEF)
