The creation, maintenance, and management of Information Product (IP) systems that are used by organizations for complex decisions represent a unique set of challenges. These challenges are compounded when the purpose of such a systems is also for knowledge creation and dissemination. Information quality research to date has focused mainly upon…

Purpose: To overcome the high manual effort of assessments for teaching personnel, e-assessment systems are used to assess students using information systems (IS). The purpose of this paper is to propose an extension of EASy, a system for e-assessment of exercises that require higher-order cognitive skills. The latest module allows assessing…

Although there have been a number of studies on large scale implementation of proprietary enterprise information systems (EIS), open-source software (OSS) for EIS has received limited attention in spite of its potential as a disruptive innovation. Cost saving is the main driver for adopting OSS among the other possible benefits including security…

The purpose of this thesis is to improve our understanding of sensemaking process as a basis for building better systems to assist sensemaking. Sensemaking is the task of creating an understanding of a problem or task so that further actions may be taken in an informed manner. Sensemaking is a pre-requisite for many other tasks such as decision…

Learning in complex and ill-structured knowledge domains requires accommodation of multiple perspectives embedded in authentic activities and the reconciliation of those perspectives with personal beliefs resulting in conceptual change. Cognitive flexibility hypertext systems support that process by enabling learners to explore authentic cases…

User participation and its relationship to system success have been discussed in the information systems (IS) literature from many theoretical and practical perspectives. In reality, most of this discussion is grounded in empirical research that has yielded mixed results on the importance of user participation and its relationship to system…

Purpose: The aim of this paper is to describe a project to provide an online web portal that can be used as a front-end for all university users--students, teachers, staff--and services, library, administration, e-learning, and e-mail. Design/methodology/approach: The profile model proposed is mainly inheritable, defined by profile components with…

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…

Presents an enriched video metadata framework including video authorization using the Video Annotation and Summarization Tool (VAST)-a video metadata authorization system that integrates both semantic and visual metadata-- metadata integration, and user level applications. Results demonstrated that the enriched metadata were seamlessly…

Presents a framework for modeling the content of information objects such as documents and video programs based on observation of how users interact with those objects in the course of information seeking and use. Identifies four categories of potentially observable user behaviors: examination, retention, reference, and annotation. (AEF)

The concept of EPSS (electronic performance support systems) originated in business settings. Recently, there have been many attempts to apply the concept to schools: educational EPSSs (E-EPSSs) have become available on the Web. However, there is little evaluation research and few evaluation frameworks for these emergent E-EPSSs. The primary…

Results from user studies support the importance of genre and task in interface design and effectiveness of filtering of electronic news. Preliminary results from a study on effectiveness of predicting interesting Web pages based on the content of previously visited pages suggest a great similarity between reading electronic news and browsing the…

The University of Illinois at Urbana-Champaign (UIUC) has a large campus computer network serving a community of about 20,000 users. With such a large network, it is inevitable that there are a wide variety of technologies co-existing in a multi-vendor environment. Effective network monitoring tools can help monitor traffic and link usage, as well…

Reports on an experiment in which detailed logging of the use of experimental information systems was used to determine the optimal configuration of the systems for users. Results suggest that systems can be created for users by analysis of the interaction of design features with personal characteristics such as cognitive abilities. (Author/LRW)
