Compares the indexing structure of icons with principles used for traditional indexing. A sample of 15 library homepages was drawn from the total population of the United States library homepages. Semiotics theory was used to study the icons. Analysis and results are outlined. (AEF)

This paper discusses bibliographic control of knowledge resources on the World Wide Web. The first section sets the context of the inquiry. The second section covers the following topics related to metadata: (1) definitions of metadata, including metadata as tags and as descriptors; (2) metadata on the Web, including general metadata systems,…

The heterogeneous environment of information retrieval on the World Wide Web has brought the recognition for the need of interoperability among diverse systems to the fore. In subject retrieval, users encounter not only different vocabularies and schemes, but also different languages. As a result, there has been a flourish of projects in the last…

Argues that the first phase of the Web is communication through shared knowledge. Predicts that the second side to the Web, yet to emerge, is that of machine-understandable information, with humans providing the inspiration and the intuition. (CR)

Discusses the role of ontology in knowledge representation, including enabling content-based access, interoperability, communications, and new levels of service on the Semantic Web; reviews current ontology generation studies and projects as well as problems facing such research; and discusses ontology mapping, information extraction, natural…

Discusses concept maps and describes an extension to computer-based concept mapping tools that provides representational capabilities that allows students to express their knowledge more fully by incorporating dynamic media-sound, video, and animated images. Explains multimedia knowledge maps, accessibility via Web browsers, and possible future…

Argues that there is a need to develop dynamic systems for structuring data to create information access and for allowing users to incorporate that information into their own knowledge base. Describes a system built on a simple, powerful content model. (DDR)

This paper presents an overview of World Wide Web-enabled databases that dynamically generate Web materials and focuses on the use of this technology to support collaboration, knowledge construction, and communication. Database applications have been used in classrooms to support learning activities for over a decade, but, although business and…

Argues that evolution is a process that occurs within the curriculum as well as within the physical universe. Provides an example that involves student presentations. Discusses the transition from poster presentations to electronic presentations via the World Wide Web. (DDR)

Cognitive flexibility is indispensable for applying knowledge to new situations. The development of this ability depends on certain conditions such as the attainment of a deep comprehension of the subject matter and the exposure to different knowledge representations. This paper focuses on these conditions and describes a study designed to foster…

This paper presents a hybrid course framework at the Teachers College at Columbia University (New York) that seamlessly integrates a traditional course plan designed for on-campus students with an online course plan designed for distance learning students. Based on innovative teaching and learning principles, the course encourages active…

This study examined the use of concept maps for Web-based applications in higher education. The purpose of the project was to design concept maps that could serve as prototypes for navigating and searching Internet resources. It also explored the value of concept mapping as a method of bibliographic retrieval for the ERIC database. Following an…

Reports on the design of an automated query system to help pharmacologists access the Derwent Drug File (DDF). Topics include knowledge types; knowledge representation; role of the search intermediary; vocabulary selection, thesaurus, and user input in natural language; browsing; evaluation methods; and search statement generation for the World…

Describes a project in which student teachers chose science exhibits and created webpages to communicate some aspect of the underlying science in the exhibit. Student teachers participating in the project developed personal understanding of some difficult areas in science. (DDR)

This brief offers an initial look at one science site on the World Wide Web (The Why Files: http://whyfiles.news.wise.edu) in order to consider the educational potential of this technology. The long-term goal of the studies of this site is to understand how the World Wide Web can be used to enhance science, mathematics, engineering, and technology…
