Information customization is a client-side activity designed to pick up where information filtering leaves off. This article describes a vision of information customization and chronicles the development of a proof-of-concept prototype, Cyberbrowser, for customizing information on the Web. (Author/AEF)

In systems that support query-based searching, the presence of multilingual content affects the search technology and user interface components that support query formulation, document selection, and query refinement. A categorization-based selection model is described that is based on rapidly constructed word-by-word gloss translations. An…

Discusses information-seeking strategies in information retrieval systems, including Web search engines, and focuses on an in-depth investigation of shifts in the micro-level of user goals, namely interactive intention and information-seeking strategies. Discusses implications of the results for the design of adaptive information retrieval…

Most libraries don't have the resources to cross-platform and cross-version test all of their JavaScript coding. Many turn to WYSIWYG; however, WYSIWYG editors don't generally produce optimized coding. Web developers should: test their coding on at least one 3.0 browser, code by hand using tools to help speed that process up, and include a simple…

Describes initial investigations into the problems encountered when college students undertake online group projects and introduces a method for designing intelligent software agents capable of recognizing and alleviating problems concerned with the maintenance roles of group project work. Discusses computer mediated communication and user…

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. (AEF)

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.

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.
