The MARIE project explores knowledge-based information retrieval of captioned images of the kind found in picture libraries and on the Internet. MARIE's five-part approach exploits the idea that images are easier to understand with context, especially descriptive text near them, but it also does image analysis. Experiments show MARIE prototypes…

Focuses on self-service, seamless, Web-based libraries--electronic libraries created by information professionals, Meta sites for the 21st Century where users with average Internet skills can find quality Web sites. Discusses content, design, effective implementation, and final evaluation. (AEF)

Defines the contextual classification model, comparing it to the traditional metadata models from which it evolved. Using the MetaData Object Manager (M.O.M) as an example, discusses the use of Contextual Classification in developing this system, and the organizational, performance and reliability advantages of using an external (to the data…

Introduces a Web authoring and publishing system, DAPHNE (Distributed Authoring and Publishing in a Hypertext and Networked Environment). Addresses DAPHNE's system architecture and design principles, key features, new developments--especially those regarding integration of a workflow for management of multilingual Web sites, and the possibility of…

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)

We apply the object oriented software engineering (OOSE) design methodology for software objects (SOs) to learning objects (LOs). OOSE extends and refines design principles for authoring dynamic reusable LOs. Our learning object class (LOC) is a template from which individualised LOs can be dynamically created for, or by, students. The properties…

Edutella is an RDF-based E-Learning P2P network that is aimed to accommodate heterogeneous learning resource metadata repositories in a P2P manner and further facilitate the exchange of metadata between these repositories based on RDF. Whereas Edutella provides RDF metadata repositories with a quite natural integration approach, XML metadata…

This article presents an approach and tools that can help learners appropriate a Web-based learning curriculum and become active participants in their learning. The approach is based on a detailed modeling of the curriculum and intends to equip the learners with different computer-based tools facilitating a multiple point of view perception of the…

This paper examines inclusive design delivery through interface design, with a particular focus on access to healthcare resources for seniors. The goal of the project was to examine how seniors are able to access drug information using two different online systems. In the existing retrieval system, pills are identified using a standard search…

The article presents a new technology design methodology that the authors have termed "Bonded Design" and that was applied by two intergenerational teams comprising adults and grade-three elementary school students in one case, and adults and grade-six students in a second case. The objective of each team was to design a low-tech web…

Background: Singapore launched the first Masterplan in 1997 to guide the integration of ICT (information and communication technology) in education. Since then many schools have started to explore using ICT in their curricula. The school reported in this paper developed a web-based learning environment to assist students in the use of ICT.…

It seems a foregone conclusion that repositories for reusable learning objects (RLOs), based on common standards and supported by suitable search facilities, will foster a global economic market in the production of RLOs. Actual reuse will support producers of high-quality RLOs, and other producers will be unable to compete, i.e. competition…

This chapter states and explains that a Learning Design is the result of a knowledge engineering process where knowledge and competencies, learning design and delivery models are constructed in an integrated framework. We present a general graphical language and a knowledge editor that has been adapted to support the construction of learning…

This book summarizes and synthesizes current thinking on problem solving and explores ways in which computers can be used in problem solving to help users gain expertise in their domains of interest. Topics in the nine chapters include an introduction to problem solving including a definition of problems; an overview followed by detailed…

In December 1994, DePauw University (Greencastle, Indiana) began developing plans for creating its World Wide Web-based campus wide information system (CWIS), DePauwINFO. Thirteen team members were recruited whose interests were intentionally diverse to ensure a broad representation of the entire campus community. A project timeline was proposed…
