Broadbutton Node Linking -- A Practical Evaluation BIBA 1-22
  Duncan Langford
An earlier paper [1] described a possible new approach to the problem of navigating within a large hypertext system, through the use of additional 'broadbutton' links. This paper, which does not assume previous knowledge of broadbutton linking, describes some practical tests of the broadbutton concept, and evaluates results.
Effectiveness of Information Retrieval Systems Used in a Hypertext Environment BIBA 23-46
  Jacques Savoy
In most hypertext systems, information retrieval techniques emphasize browsing or navigational methods which, unfortunately, are not thorough enough to find all relevant material, especially when the number of nodes and/or links becomes very large. This paper reviews briefly the main query-based search techniques currently used in hypertext environments. Next, after explaining our own experimental methodology, this study concentrates on the retrieval effectiveness of these retrieval strategies. Based on our results, some discussion points are clarified and some interesting avenues for improving search effectiveness are promoted.
The Amsterdam Hypermedia Model: Extending Hypertext to Support Real Multimedia BIBA 47-69
  Lynda Hardman; Dick C. A. Bulterman; Guido Van Rossum
We present a model of hypermedia that allows the combination of 'HYPERM-structured' information with dynamic multimedia information. The model is derived by extending the Dexter hypertext reference model and the CMIF multimedia model. The Amsterdam hypermedia model allows the following, in addition to the model provided by Dexter:
  • the composition of multiple dynamic media, in order to specify a collection
       of time-based media making up a complete multimedia presentation;
  • the definition of channels for specifying default presentation information,
       allowing the specification of the presentation characteristics of nodes at a
       more general level than that for an individual node;
  • the composition of existing presentations into larger presentations, taking
       into account possible clashes of resource usage;
  • the inclusion of temporal relations while maintaining the separation of
       structure and presentation information, where time-based relationships are
       treated as presentation information;
  • the definition of context for the source and destination anchors of a link in
       order to specify the parts of a presentation affected on following the link. The Amsterdam hypermedia model enables the description of structured multimedia documents, incorporating time at a fundamental level, and extending the hypertext notion of links to time-based media and compositions of different media.
       The paper is organised as follows. The Dexter hypertext model and the CMIF multimedia model are summarised, and their limitations for use as a more general hypermedia model are discussed. The extensions included in the Amsterdam hypermedia model are described and a summary of the resulting model is given.

    Supporting Hypermedia Services in the User Interface BIBA 85-101
      Charles J. Kacmar
    This paper presents an architecture for developing hypermedia systems in which hypermedia services are provided primarily through the interface and hypermedia components of an application. The architecture relieves the application component and its developers from the issues associated with hypermedia. It also allows a common hypermedia engine and interface to be used in multiple applications to present a consistent view of a hypermedia model. A prototype of the architecture is presented with examples of the hypermedia facilities which can be provided. The discussion associated with the prototype demonstrates that many of the common features of pure hypermedia systems can be supported. Limitations and future research issues also are discussed.
    Open and Reconfigurable Hypermedia Systems: A Filter-Based Model BIBA 103-118
      Gary Hill; Rob Wilkins; Wendy Hall
    The need for open hypermedia systems has been well-argued by various authors. In this paper we discuss the Microcosm model for open hypermedia and show how filters have been used to extend this model both for greater efficiency and to make it totally reconfigurable. This enables users to tailor the functionality of the system to meet their own requirements, for example to select different sets of links, or to add navigation tools. The implementation of a management system for filters is described, and examples of how it has been used to extend the functionality of the model are presented, in particular the use of filters to design and implement a set of navigation tools for Microcosm. This latter case study demonstrates the power and flexibility of the filter-based model since all navigation tools for the system can be implemented as filters. The filter technology is discussed in the context of Microcosm but can be generalised to other hypermedia systems.
    Developing a Hypertext Geographic Information System for the Norfolk and Suffolk Broads Authority BIBA 119-143
      Lesley A. Gardner; Ray J. Paul
    This paper describes an experiment conducted into the use of hypertext as an information system development tool for Geographical Information Systems, using the Norfolk and Suffolk Broads Authority as a case study. The use of hypertext as a software engineering development tool has been extensively explored with some success. The Norfolk and Suffolk Broads Authority is the management body of an important environmentally sensitive area, the Norfolk and Suffolk Broads. The obligations of the Broads Authority require the co-ordination of many diverse forms of information. This may best be served by using an integrated information system that is capable of supporting the full range of the Broads Authority's responsibilities. This paper reports on the initial findings of an investigation into the properties of hypertext as a development tool for a complex information systems and the appropriateness of this approach and its implementation in general.

    Hypermuse: A Prototype Hypermedia Front-End for Museum Information Systems BIBA 165-186
      Alan Poulter; Goff Sargent; Anne Faxy
    A model is proposed of a hypermedia package fronting an existing database package. This would utilise the advantages of each. Museums have text databases of their collections that, for public use, would require navigational access. The paper focuses on the design of a hypermedia front end for a hypothetical museum, using services information and object records from real museums. The resulting Hypermuse system consists of a 386 PC running dBase as a back end and an Apple Macintosh LC running HyperCard as the front end: a serial link, managed at each end by the packages pcAnywhere and Commstalk respectively, connects these machines. The prototype system is evaluated and found basically sound but in need of minor improvements in the front end. It is concluded that the concept is a viable one for implementation in museums.
    Navigation Without Links and Nodes Without Contents: Intensional Navigation in a Third-Order Hypermedia System BIBA 187-204
      Hans C. Arents; Walter F. L. Bogaerts
    The key to unlocking the navigation potential of hypertext and hypermedia systems lies in a more semantics-aware indexing of the interrelated information stored in these systems. We first highlight briefly the different indexing techniques which have been proposed for hypertext and hypermedia systems, and we then discuss the so-called semantic hyperindexing technique which we have recently developed to represent the significant relations between hypertextual information. We discuss in detail how this technique is being used to support intensional navigation in a third-order hypermedia system, based on the definition of meaningful traversal trails between semantically associated nodes, which the reader can navigate freely at his own discretion while still being gently guided by the system. Finally, we consider the graphical notation which we have developed to help the authors in visualizing these intensionally defined traversal trails, and we discuss how the use of this notation improves the productiveness of the authors during trail design.
    PEDRO -- The Spanish Tutor. A Hypertext-Based Intelligent Tutoring System for Foreign Language Learning BIBA 205-230
      Marios C. Angelides; Geraldine Gibson
    The objective of this paper is to introduce Hypertext as an alternative paradigm in developing a full-scale Intelligent Tutoring System to the traditional Expert Systems paradigm that has dominated for years Intelligent Tutoring Systems development. This paradigm has been employed in the development of PEDRO, an Intelligent Tutoring System for foreign language learning. PEDRO -- The Spanish Tutor is an Intelligent Tutoring System designed to assist intermediate level students with their learning of Spanish grammar, by testing their knowledge of regular and irregular verbs. This paper describes PEDRO's architecture, functionality and pedagogical strategy. PEDRO has been developed using HyperCard II.
