    Clustering semantics for hypermedia presentation

    Get PDF
    Semantic annotations of media repositories make relationships among the stored media and relevant concepts explicit. However, these relationships and the media they join are not directly presentable as hypermedia. Previous work shows how clustering over the annotations in the repositories can determine hypermedia presentation structure. Here we explore the application of different clustering techniques to generating hypermedia interfaces to media archives. This paper also describes the effect of each type of clustering on the end user's experience. We then generalize and unify these techniques with the use of proximity measures in further improving generated presentation structur

    Improving media fragment integration in emerging web formats

    Get PDF
    The media components integrated into multimedia presentations are typically entire files. At times the media component desired for integration, either as a navigation destination or as coordinate presentation, is a part of a file, or what we call a fragment. Basic media fragment integration has long been implemented in hypermedia systems, but not to the degree envisioned by hypermedia research. The current emergence of several XML-based formats is beginning to extend the possibilities for media fragment integration on a large scale. This paper presents a set of requirements for media fragment integration, describes how standards currently meet some of these requirements and proposes extensions to these standards for meeting remaining requirements

    Hypermedia as medium

    Get PDF
    Claims and rebuttals that hypermedia (the associative, nonlinear interconnection of multimedia materials) is a fundamentally innovative means of thinking and communicating are described. This representational architecture has many advantages that make it a major advance over other media; however, it also has several intrinsic problems that severly limits its effectiveness as a medium. These advantages and limits in applications are discussed

    Finding the way : navigation in hypermedia

    Get PDF
    If navigation is recognized as a fundamental problem experienced by hypermedia users, then navigation merits further investigation. This review will identify observed navigational problems, suspected causes, and proposed solutions. To investigate the problem, it is necessary to examine methods used to sequence hypermedia components and to identify the various schemes used for navigation. Information resulting from the review of literature will serve as the basis for a project evaluating current multimedia software packages designed to develop reading skills. The findings will also provide the media specialist or professional educator with a framework for evaluation and subsequent utilization of multimedia learning materials. Additionally, the information compiled can serve as a guide to professionals endeavoring to create their own hypermedia materials

    An Open Framework for Integrating Widely Distributed Hypermedia Resources

    No full text
    The success of the WWW has served as an illustration of how hypermedia functionality can enhance access to large amounts of distributed information. However, the WWW and many other distributed hypermedia systems offer very simple forms of hypermedia functionality which are not easily applied to existing applications and data formats, and cannot easily incorporate alternative functions which would aid hypermedia navigation to and from existing documents that have not been developed with hypermedia access in mind. This paper describes the extension to a distributed environment of the open hypermedia functionality of the Microcosm system, which is designed to support the provision of hypermedia access to a wide range of source material and application, and to offer straightforward extension of the system to incorporate new forms of information access

    Finely integrated media for language learning

    Get PDF
    FLUENT, an immersive foreign‐language learning environment, was developed without recourse to hypermedia techniques. Nevertheless, if one accepts the premisses, proposed in this paper, on which the idea of hypermedia has been constructed, FLUENT shows a strong relationship with it. The paper discusses this relationship after attempting to distil the essence of educational hypermedia, and after presenting a taxonomy of media for language learning

    What is the problem to which interactive multimedia is the solution?

    Get PDF
    This is something of an unusual paper. It serves as both the reason for and the result of a small number of leading academics in the field, coming together to focus on the question that serves as the title to this paper: What is the problem to which interactive multimedia is the solution? Each of the authors addresses this question from their own viewpoint, offering informed insights into the development, implementation and evaluation of multimedia. The result of their collective work was also the focus of a Western Australian Institute of Educational Research seminar, convened at Edith Cowan University on 18 October, 1994. The question posed is deliberately rhetorical - it is asked to allow those represented here to consider what they think are the significant issues in the fast-growing field of multimedia. More directly, the question is also asked here because nobody else has considered it worth asking: for many multimedia is done because it is technically possible, not because it offers anything that is of value or provides the solution to a particular problem. The question, then, is answered in various ways by each of the authors involved and each, in their own way, consider a range of fundamental issues concerning the nature, place and use of multimedia - both in education and in society generally. By way of an introduction, the following provides a unifying context for the various contributions made here

    A model for hypermedia learning environments based on electronic books

    Get PDF
    Designers of hypermedia learning environments could take advantage of a theoretical scheme which takes into account various kinds of learning activities and solves some of the problems associated with them. In this paper, we present a model which inherits a number of characteristics from hypermedia and electronic books. It can provide designers with the tools for creating hypermedia learning systems, by allowing the elements and functions involved in the definition of a specific application to be formally represented A practical example, CESAR, a hypermedia learning environment for hearing‐impaired children, is presented, and some conclusions derived from the use of the model are also shown

    Teaching new media composition studies in a lifelong learning context

    Get PDF
    Governmental proposals for lifelong learning, and the role of Information and Learning Technologies/Information Communication Technologies (ILT/ICT) in this, idealistically proclaim that ILT/ICT empowers learners. A number of important governmental funding initiatives have recently been extended to the development of ILT in further education, which provides a particularly appropriate environment for lifelong learning. Yet little emphasis is given to more problematic research findings that students may be ‘disarmed’ in the process of learning to use technology. In the current global shift towards new forms of multimedia literacy, it is important to recognize human diversity by carrying out research focusing on the actual problems students face in adapting to Web‐based technology as a new authoring medium. A case study into multimedia creative composition carried out with FE students in 1996–9 found that students tend to experience a problematic but potentially useful period of ‘creative mess’ when authoring in multimedia, and that ‘scaffolding’ strategies can be useful in overcoming this. Such strategies can empower students to derive benefits from multimedia composition if close attention is given to the setting up of the learning environment: a teachers’ model for supporting novice hypermedia authors in further education is proposed, to assist teachers to understand and support the learning processes students may undergo in dynamic composition using new media technology
