Choices made on data visualizations guide how users make meaning of the information presented. This research investigates design decisions made on 115 state-level dashboards reporting school safety data. Using pre-determined codes drawn from a framework of visualization rhetoric, dashboard characteristics were described and analyzed. Analysis…

With changing user expectations, many libraries are moving toward digital content. Accessible from anywhere at any time, digital content provides users with efficient, on-demand information experiences. Accordingly, librarians are presented with challenges and opportunities to build, manage, and implement outreach strategies that promote their…

Details the rationale, evaluation and implementation of use scenarios-structured narrative descriptions of envisioned system use-in the development of the Alexandria Digital Earth Prototype (ADEPT). Discusses the strengths of the scenario approach, obstacles to their use, and lessons learned in the overall development process. (Author/AEF)

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)

Coordinated index concepts are compound-index concepts that express a relationship between concepts that function as simple subject descriptors. The Condorcet Query Engine, a prototype query engine that can be run over the World Wide Web, demonstrates the feasibility of a query engine that can handle both simple and coordinated index concepts,…

This research begins to refine a cognitive model of interactive information seeking for use in the design of information retrieval (IR) systems. The research reported in this paper critically examines several interactive information seeking and retrieval models that have emerged over the last two decades. Building primarily on the stratified…

Librarians providing information services electronically must create useful information systems. This article illustrates that the effectiveness of an information system is characterized by its readability, browsability, searchability, and interactive assistance. Describes the concept of interactive assistance and how it relates to information…

This concept paper begins by arguing that Integrated Performance Support Systems (IPSS) are an imperative for boosting productivity in the workplace and gaining competitive advantage in the marketplace. It then presents the framework for an IPSS solution to meet the challenges of the 1990s. Discussion of the implementation of an IPSS solution…

Built using a distributed architecture, this prototype distributed information retrieval system uses statistical ranking techniques to provide better service to the end user. Distributed architecture was shown to be a feasible alternative to centralized or CD-ROM information retrieval, and user testing of the ranking methodology showed both…

Digital libraries are moving from research and development into commercial use. If they are to realize their full potential, however, the experiences of end users need to be taken into account from the earliest stages of design. Those end users are typically individuals who have no particular skills in information retrieval, and are accessing…

Describes a study that investigated subject retrieval in a group of humanities databases. Scatter by subject field and type of search term is discussed, the effectiveness of natural language and of controlled vocabulary are compared, and implications for system designers concerned with end-user searches in the humanities are suggested. (37…

Describes the design of a customized online service at the Lister Hill Library (Alabama) that used a dial-in modem system to provide remote access to medical research materials. Problems with hardware and software incompatibility are discussed, user training is described, and the successful results are reviewed. (LRW)

Reviews the historical development and technological features of hypertext, a computerized nonlinear text system. Three major areas of applications are identified: (1) instruction, (2) electronic publishing and online databases, and (3) thinking and authoring tools. Research issues in document processing and education are also discussed. (28…

Describes the design and development of a prototype expert system called ONLINE-EXPERT that helps users select online databases and vendors that meet users' needs. Search strategies are discussed; knowledge acquisition and knowledge bases are described; and the Analytic Hierarchy Process (AHP), a decision analysis technique that ranks databases,…

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)
