Typical web lectures consist of two different kinds of media linked together: an audio- or video-recording and the corresponding slides or desktop recording. Both media are synchronized so that the slide or image shown corresponds to the position currently played in the time-based media stream. Web lectures are thus composite media consisting of a…

Describes international standards for information technology, including an emerging standard for interchangeable multimedia and hypermedia scripts. Highlights include data interchange standards; HyTime (Hypermedia/Time-Based Structuring Language); DSSSL (Document Style Semantics and Specification Language); SPDL (Standard Page Description…

Adaptation and personalization services in e-learning environments are considered the turning point of recent research efforts, as the "one-size-fits-all" approach has some important drawbacks, from the educational point of view. Adaptive Educational Hypermedia Systems in World Wide Web became a very active research field and the need of…

There is a common assumption that hypermedia navigation is influenced by a learner's style of thinking, so people who are inclined to apply sequential and analytical strategies (left-thinkers) are thought to browse hypermedia in a linear way, whereas those who prefer holistic and intuitive strategies (right-thinkers) tend towards non-linear paths.…

Presents the history of the Internet with specific emphasis on Mosaic; discusses hypertext and hypermedia information; and describes software and hardware requirements. Sidebars include information on the National Center for Super Computing Applications (NCSA); World Wide Web browsers for use in Windows, Macintosh, and X-Windows (UNIX); and…

Explores an approach to analysis and modeling of computer-supported collaborative writing, which captures the structure of user behavior as they interact with a computer system. Shows that patterns of interactive behaviors of the users were influenced by the system design. Suggests that this approach is worth pursuing and may be integrated with…

This discussion of educational applications of user interfaces covers the benefits of adopting database techniques in organizing multimedia materials; the evolution of user interface technology, including teletype interfaces, analogic overlay graphics, window interfaces, and adaptive systems; application design problems, including the…

The authors developed a Web-based negotiation system that is closely modeled on real-world transactions. This paper illustrates the generality of the system by discussing two disparate applications of the system: one taken from business and the other from collaborative e-learning. The application generates, in real time, transparency-controlled…

Noting that the merging of various types of media with the computer has presented the field of education with a hybrid technology called interactive multimedia (also referred to as hypermedia), this digest begins by defining this technology as "the integration of text, audio, graphics, still image, and moving pictures into a single,…

Describes an integrated approach to similarity coefficients that allows multiple index dimensions to be integrated into a single, flexible navigation tool. Categorizes different types of similarity measures by the kinds of index terms they employ and describes the underlying similarity measures. (Author/AEF)

Students are, increasingly, digital content producers, and participate extensively in evolving online social networks. The emergence of the former represents subtle changes in students' experience of images, audience, copyright, ownership of learning, and technology. Experiencing the latter places students in an awkward position in terms of…

This paper describes and analyses the experience of designing, installing and evaluating a farmer-usable touch screen information kiosk on cattle health in a veterinary institution in Pondicherry. The contents of the kiosk were prepared based on identified demands for information on cattle health, arrived at through various stakeholders meetings.…

Discussion of library information systems focuses on the idea of including user-supplied data (USD) in libraries' automated catalogs. Hypertext is mentioned, the information explosion and the ability to selectively retrieve information is considered, and the value of user input in evaluating the relevance of material is discussed. (12 references)…

Provides historical background on hypertext and hypermedia; discusses their use in the humanities; gives examples of hypersystem applications in the humanities; and examines libraries' roles in the use of hypersystems in the humanities, including financing, implementation, evaluation, and humanist attitudes toward technology and hypersystems. (178…

Discusses intelligent filtering systems and describes work in the INFOS (Intelligent News Filtering Organizational System) project designed to automatically categorize data as relevant or irrelevant based on user interests. The filtering is performed by combining keyword-based hill climbing, knowledge-based conceptual representation via WordNet,…
