摘要:

This article describes efforts to produce a hypertext design methodology supporting end users in the design and construction of small to medium sized hypertext documents. Existing hypertext methodologies are reviewed and analysed, and on the basis of this material plus data drawn from the authors' own experiences and other developments, a new design methodology is proposed.

摘要:

A method for multimedia presentation design is described. The method consists of design principles based on cognitive psychology, media selection guidelines that utilise definition of information and media types, validation guidelines for media combination and techniques for directing the user's attention in multimedia sequences. Contact points are proposed for design effects to link content themes across different media. The method is illustrated with a theatre booking application, and the techniques for attention design are described by experimental studies on a presentation before and after the application of the attention directing guidelines. Method validation studies are described briefly followed by a discussion of future work.

摘要:

In this paper we show how hypermedia patterns can be combined with design methods in a synergistic way. We first review the state of the art on development methods, emphasizing the OOHDM development process; we next present design and hypermedia patterns as a conceptual tool to record and convey design experience in the hypermedia field; some examples are briefly introduced. Then we discuss two different ways of incorporating hypermedia patterns into the development life-cycle: by including them as new higher level design primitives in a method, and by using patterns as guidelines during the design process. We finally present some further work in this area.

摘要:

In this paper, a quantitative evaluation approach to assess the quality of sites called Website Quality Evaluation Method (QEM) is proposed. This prescriptive and descriptive approach might be useful to evaluate and compare quality characteristics and attributes in different phases of a Web product lifecycle. Particularly, to discuss this methodology, we evaluate the level of accomplishment of required quality characteristics (like usability, functionality, reliability, efficiency, and derived subcharacteristics) in six typical academic sites. At the end of the evaluation process, a ranking for each selected site is obtained. Specifically, the evaluation process generates elemental, partial, and global indicators or quality preferences that can be easily analyzed, backward and forward traced, justified, and efficiently employed in decision-making activities. Hence, conclusions about the state-of-the-art of the quality in the operative phase of these sites can be drawn. In addition, recommendations for improvements can be given. The outcomes are indicators of the percentage of fulfillment of stated quality requirements. Finally, concluding remarks and in-progress research is presented.

摘要:

Employing scientific investigation is essential to understanding hypermedia processes and products, making hypermedia authoring a science rather than an art. This paper describes a case study aimed at validating empirically metrics proposed to measure the development effort involved in authoring a hypermedia application. The case study is one of the empirical evaluations that we have conducted and it has been planned according to a scientific method of research. Our objective is to improve hypermedia authoring by measuring some quality characteristics of hypermedia applications and the processes involved in developing hypermedia applications.

摘要:

If we are to improve our ability to reliably and consistently create high quality hypermedia applications then we need to improve our understanding of the development process and its relationship to the quality of the end applications. In this paper we consider the role of descriptive process modeling in understanding and subsequently improving the hypermedia development process. We will look at problems with existing hypermedia development processes and the role which design tools, methods and models can play. We then go on to consider how descriptive process modeling can be used to model hypermedia development processes and subsequently identify potential flaws within these processes. We propose a hypermedia development process reference model, and an associated modeling and process assessment method that provides the mechanisms necessary for measuring and improving hypermedia development. We provide some examples that demonstrate the validity of the approach. The result is a technique which is capable of providing significant improvements in the manageability, consistency and cost-effectiveness of the development process and hence the quality of the applications which result from this process.

摘要:

One requirement placed on open hypermedia technology is the ability to support relationship management in large-scale information environments. We examine the issues of scalability encountered in supporting open hypermedia in a large-scale software development environment. The World Wide Web is discussed as an alternative approach to supporting relationship management in these environments and we identify reasons why open hypermedia is a superior approach. We also report on a research project where the Chimera open hypermedia system was used to support the relationship management needs of an industrial-scale development project of an aerospace organization. The results of this project supply insights to developers about the implications of supporting data scalability in open hypermedia systems. We conclude by evaluating the level of scalability achieved by our efforts and describe our future plans with respect to supporting additional orders of magnitude.

摘要:

In this paper, we consider the issue of integrating different structure services within a component-based open hypermedia system. We do so by considering the task of collaborative editing, which calls for a variety of different structures traditionally supplied by different structure services. We discuss the nature of collaborative editing and how it can be supported by a combination of spatial and navigational hypermedia services. We then present a component-based open hypermedia system architecture and describe various methods of integrating different structure services provided within such an architecture. We show the advantages of integration within a component-based framework over other means of integration, highlighting some of the main advantages of the component-based approach to open hypermedia system design and implementation.

摘要:

Early hypertext systems were monolithic and closed, but newer systems tend to be open, distributed, and support collaboration. While this development has resulted in increased openness and flexibility, integration or adaptation of various different tools (such as content editors, viewers, services, or even other link servers) has remained a tedious task. Many developers were implementing essentially similar components, simply for the benefit of having their own platform on which to experiment with hypertexts.
