A concern, however, with the educational use of hypermedia is that of user navigation. The issue is how, on the one hand, to prevent the user from becoming overwhelmed with information and losing track of where they are going, while on the other hand permitting them to make the most of the facilities the hypermedia offers. One approach to remedy this is to restrict the number of links made avai...

Adaptivity is a particular functionality of hypermedia that may be applied through a variety of methods in computer-based learning environments used in educational settings, such as the flexible delivery of courses through Web-based instruction. Adaptive link annotation is a specific adaptive hypermedia technology whose aim is to help users find an appropriate path in a learning and information...

This paper considers the use of XLink as a linking mechanism for both the Web and for open hypermedia systems. We present a comparison between the open hypermedia interchange format (OHIF) and XLink and describe a XLink implementation based on this comparison. Finally, we discuss whether XLink can bridge the waters between the Web and open hypermedia systems.

This paper presents two design patterns for the hypermedia domain: ‘Navigational Contexts’ and ‘Information on Demand’. They are applied in two different aspects of hypermedia applications design: the design of healthy navigational structures and the design of understandable and usable hypermedia interfaces, respectively. These two patterns are part of an effort for developing a Pattern Languag...

As applications in the World Wide Web are growing steadily regarding both size and functionality, database support plays a more and more important role. The technical questions of integrating databases and the WWW have been discussed and answered within the last few years, but the area of design methodologies still lacks a comprehensive framework for modeling these kinds of applications. Establ...

The novel information retrieval system OMNIS is supported by the fulltext database system Myriad, and provides archiving, disclosing, and searching functions at drastically reduced costs. The user interface of OMNIS has been created in an intuitive way and compared with the Dexter Hypertext Reference Model, two main differences will be noticed: On the one hand, OMNIS does not support arbitrary ...

The World Wide Web continuously provides rapid access to information, and numerous information resources, virtually unlimited. convenience interactivity of its usage encourage people turn it in the educational process rather often while teaching or studying unfamiliar topics. Hypertext resources different kinds have become a virtual environment. They offer new opportunities for structuring, pre...
