Today, there is a real challenge to enable personalized access to information. Several systems have been proposed to address this challenge including Adaptive Hypermedia Systems (AHSs). However, the specification of adaptation strategies remains a difficult task for creators of such systems. In this paper, we consider the problem of the definition…

Online learning material that students use by themselves is one of the typical usages of algorithm animation (AA). Thus, the integration of algorithm animations into hypertext is seen as an important topic today to promote the usage of algorithm animation in teaching. This article presents an algorithm animation viewer implemented purely using…

In this article, the main characteristics of the educational browser YADBrowser are described. One of the main objectives of this project is to define new languages and object models which facilitate the creation of educational applications for the Internet. The fundamental characteristics of the object model of the browser are also described.…

Describes HTML (HyperText Markup Language) and its use on the Internet's World Wide Web, including main HTML tags and their syntaxes. Alternatives to HTML, such as Adobe's Acrobat software and Sun's new Java application language, are briefly described. (Author/LRW)

This book and three accompanying floppy disks introduce HyperCard 2.1 for the Macintosh microcomputer and its programming component, HyperTalk, to educators. The first four chapters introduce the basics of HyperCard, including its structure, which is based on a hierarchy of units; the use of tools and graphics; and ways of linking information…

Discusses new trends in the World Wide Web. Highlights include multimedia; digitized audio-visual files; compression technology; telephony; virtual reality modeling language (VRML); open architecture; and advantages of Java, an object-oriented programming language, including platform independence, distributed development, and pay-per-use software.…

Describes the basics of Standard Generalized Markup Language (SGML), an international standard which separates structure and content of a document; states background information and objectives; presents an SGML document; discusses the movement from conventional documents to integrated document bases; defines hypermedia/time-based structuring…

Discusses how the World-Wide Web (WWW) can be linked to the PAT system, a search engine supporting access to Standard Generalized Markup Language (SGML) encoded documents. Technical concepts are reviewed, and the operation of a PAT-to-Web gateway is explained using examples of how it is employed. (JKP)

The challenge of the semantic web is the provision of distributed information with well-defined meaning, understandable for different parties. Particularly, applications should be able to provide individually optimized access to information by taking the individual needs and requirements of the users into account. In this paper we propose a…

The role of conceptual modeling in Educational Adaptive Hypermedia Applications (EAHA) is especially important. A conceptual model of an educational application depicts the instructional solution that is implemented, containing information about concepts that must be ac-quired by learners, tasks in which learners must be involved and resources…

This paper describes the results of our efforts with regard to the design and implementation of an educational digital video library using MPEG-4 and the Synchronized Multimedia Integration Language (SMIL). The aim of our work is to integrate MPEG-4 encoding, full text indexing, high-resolution streaming, and SMIL, not only for delivering on-line…
