Proposes an information architecture for personal-history data and describes how the data model can be extended to a runtime model for a compact visualization using graphical timelines. The model groups personal-history events into aggregates that are contained in facets, crosslinks are made, and data attributes are mapped. (Author/LRW)

Discusses content-based image retrieval systems that effectively utilize information from image databases, and provides a taxonomy for approaches to image retrieval. Highlights include image retrieval architecture that supports query operators; conceptual issues; and two application prototypes. (100 references) (Author/LRW)

Describes an International Development Research Centre project that tested suitable approaches for assessing the benefits derived from information activities in developing countries. Reviews many research questions related to concepts of information and development, impact of information, and the methodological and practical constraints in its…

Describes the architecture of an anthropocentric Biomedical Information Management System prototype that is based on a network of computational components, or agents, that expert biomedical users can define, use, and refine to serve their own communication and documentation habits and needs. The innovation of the proposal, the Participatory Design…

Text similarity measurements are used to determine relationships between natural-language texts and text excerpts. The resulting linked hypertext maps can be broken down into text segments and themes used to identify different text types and structures, leading to improved information access and utilization. Examples are provided for text…

This analytical paper covers: (1) review of the terrain of information utilization; (2) posits/examines Bertram Brookes' fundamental equation of information science as a theoretical framework, and discuss our understanding of/research into, the cognitive aspects of information utilization, and (3) discusses methodological aspects for investigating…

This article focuses on a study of undergraduates writing an essay for a remedial writing course that tested two devices, an uncertainty expansion device and an uncertainty reduction device. Highlights include Kuhlthau's information search process model, and enabling technology devices for the information needs of information retrieval system…

The paper reports the results of a preliminary study of interpersonal information seeking (IS) interactions between a user and a human information source. Study showed that users specify their information needs (uncertainty) largely in terms of what they know (certainty) during the interaction. (Author)

Explores the implications of articulating the bridges that are built, usually implicitly, between metatheory and method, and between these and their ultimate interests, the doing of research; the purpose is to articulate the uses of methodology. Suggests that there is lacking a vocabulary for talking about methodology which attends to the…

Discourse analysis addresses questions regarding both spoken and written communications and can be applied to purposes and practices of information study that appear in books and journals in the field. Applications of discourse analysis to information include investigation of the social, political, and technical implications of the word…

Discussion of changes in scholarly communication due to the World Wide Web focuses on a comparison of two views of information production and use in computer-related research based on citation analysis of publications on the Web using autonomous citation indexing and a parallel citation analysis of traditional journal literature. (Author/LRW)

Describes an empirical evaluation that investigated the criteria by which designers of human-machine systems evaluate design information. Professional designers of nuclear power plant control rooms rated hypothetical information search questions in terms of relevance, importance, cost, and effort based on Rouse's model of information search…
