One of the more diffuse problems with information technology (IT) is that both users and their IT-supporters and IT-administrators have the feeling that IT leads to more work to be done. Since the boom of the WWW this got even worse. On one hand we have an easy way of making information available, on the other hand we have all the maintainance work with it. The problem is that much of the infor...

Interactive multimedia documents are rapidly becoming available on the WWW. Navigating in such large document repositories requires flexible retrieval techniques based on spatiotemporal structure. In this paper we address this issue by extending the notion of conceptual neighborhood (a concept describing similarity among relations between time intervals) to various resolution levels and higher ...

In this paper, we provide a basic introduction to several popular cooperative learning activities and explore how these activities might be modified for computer-based science learning activities. We review research that describes science programs that employ collaboration. Then, we describe innovative computerbased tools developed and/or utilized at the University of Hawaii Curriculum Research...

The 5 th International Workshop on Web Quality (WebQuality 2015) was held in conjunction with the 24 rd International World Wide Web Conference in Florence, Italy on the 18 th May 2015. This report briefly summarizes the workshop.

Knowledge-intensive processing of WWW information should be founded on clear and uniform conceptualisation. An integrated ontol-ogy covering diierent aspects of the WWW (documents, sites, network addressing, HTML code) has been laid down, upon which a knowledge base of the WWW domain is being built. This knowledge base should support \intelligent" metasearch of the Web, in particular, postproce...

World Wide Web (WWW) authors must cope in a hypermedia environment analogous to secondgeneration computing languages, building and managing all hypermedia links using simple anchors and singlestep navigation. We present a set of thirdand fouvthgeneration hypermedia functionalities, which WWW developers should consider. We ground our discussion in the hypermedia research literature, and illustra...

Current WWW clients do not directly support synchronized playback of continuos media. It is however possible to support continous media by using external programs that are controlled by the WWW client. This paper describes the design and implementation of a “Media on Demand” server which uses WWW as its user interface. Offered media include audio and video recordings of transmissions on the Int...

Es zeichnet sich ab, daß sich das WWW zur kommenden Plattform für Interaktion mit dem Benutzer entwickelt. Das hier beschriebene Projekt untersucht die Möglichkeiten, grafische Benutzeroberflächen auf das WWW abzubilden. Bildformate, CGITechniken, Java, CORBA, VRML, Plug-In-Technologien, usw. werden in einer Übersicht zusammengefaßt. Gleichzeitig wird untersucht, wie ältere Grafikanwendungen mi...

This paper examines the issues, current practices and trends for the future regarding accessing traditional databases through the World Wide Web (WWW). It is often easy to forget that the WWW has no data management facilities of its own; it is simply a “pointing” mechanism. Databases have historically focused on rich toolsets for describing, updating, and modelling data. WWW adds to this a plat...
