In this paper we describe the development and refinement of "evidence rules" and "measurement models" within the "evidence model" of the "evidence-centered design" (ECD) framework in the context of the "Packet Tracer" digital learning environment of the "Cisco Networking Academy." Using…

Examines historical and current difficulties in information retrieval, including the tendency of technology, because of the problems of scale and distribution, to make information invisible to users. Attempts to organize networked resources are described, and serendipity is proposed as a model for future retrieval. (two references) (MES)

Describes the VISION (video indexing for searching over networks) digital video library system which was developed at the University of Kansas as a testbed for evaluating automatic and comprehensive mechanisms for library creation and content-based search and retrieval of video over local and wide area networks. Discusses experimental results.…

Presents the results of an investigation of the use of links on Web pages; a content analysis was performed on 75 Web pages and their links. Results will provide a conceptual framework in which Web page design can be considered, including issues of authoring, retrieval, and built-in and on-the-fly guidance for reading and browsing. (Author/AEF)

Characterizes information retrieval systems in a network environment from a user's perspective along two axes: query and presentation. Several examples of early, current, and developing information retrieval systems are considered within this framework, and Daltext, a prototype system to support research on text-based retrieval systems, is…

This report on a machine-readable data files workshop highlights unresolved issues related to innovative approaches to collecting, describing, and providing service for computer files in research libraries. The remarks of four of the workshop speakers are presented. Margaret Johnson of the University of Minnesota gives a comprehensive review of…

Describes plans for an investigation of gopher protocol use for browsing and searching for information available via the Internet. Use of classification schemes based on traditional library models will be compared to the use of an existing gopher. Research questions, literature on related issues, construction of the classification schemes, and the…

Describes the design and development of an image database for photographs in the Ulster Museum (Northern Ireland) that used parallelism from a transputer network. Topics addressed include image processing techniques; documentation needed for the photographs, including indexing, classifying, and cataloging; problems; hardware and software aspects;…

Argues that library skills and methods used for organization of information are needed to organize Internet information resources. Four aspects of information organization are discussed: recording existence and identity of information bearing entities; acquiring these entities; providing name, title, subject, and other access information; and…

The IADIS CELDA 2012 Conference intention was to address the main issues concerned with evolving learning processes and supporting pedagogies and applications in the digital age. There had been advances in both cognitive psychology and computing that have affected the educational arena. The convergence of these two disciplines is increasing at a…
