Creation and maintenance of links in large hypermedia documents is difficult. Motivated by an application to a federal clinical practice guideline for cancer pain management, we have developed and evaluated a repertory grid-based linking scheme we call repertory hypergrids. Harnessing established knowledge acquisition techniques, the repertory hypergrid assigns each “knowledge chunk” a location in “context space”. A chunk links to another chunk if they are both close in context space. To evaluate the scheme, we conducted a protocol analysis. Six users of the guideline addressing typical cancer pain management tasks made 30 explicit links. The repertory hypergrid using a neighborhood size of 16 captures 24 of these links. With optimization, the repertory hypergrid captures 27 of the links with a neighborhood size of 13.

In recent years, there has been significant growth in the use of computer networks to support electronic delivery of information. As the volume of available information has grown, a need for powerful tools that can manage access has arisen. It has been suggested that hypertext techniques can provide such a facility. The Microcosm system is a hypertext link service developed at the University of Southampton. The system is based upon a modular architecture which allows the functionality of the system to be easily and dynamically extended. This paper describes the development of a distributed version of Microcosm based upon this modular design. The distributed system described utilises the fine granularity of the Microcosm model to support a wide range of wide possible configurations. The system also extends the document management facilities of Microcosm to allow information stored by other information services to be incorporated. The result is a system that can apply Microcosm's open linking services to a wide range of networked information.

Due to the growing complexity of modern hypertext applications, current hypertext systems require new mechanisms to support authoring and user navigation through large sets of documents connected by links. A general solution is to extent hypertext systems to cater for semantics of application domains. This requires new hypertext models providing strongly typed documents and links. Such models have been proposed and put to use in systems such as HDM and MacWeb to facilitate authoring of large hypertexts. In addition, Gram and MORE use typing and graph-based hypertext schemas for querying hyperdocuments. In this paper, we will show how query languages could be further exploited for designing sophisticated general query-based navigation mechanisms. We illustrate our examples using the Gram model and describe an implementation with the hypermedia system Multicard connected to the object-oriented database management system O2.

Information engineering is a new activity within the Telematics part of the Fourth Framework Programme for R&D of the Commission of the European Union. It is a horizontal activity that is concerned with the problems of providing easier and more selective access to information and improving the usability of information. It may be considered as applications research in support of the emerging information highways, that will enable the general public, SMES and other non-professional users to access facitilites that until now have been available almost exclusively to research workers and large corporations. The programme has been developed in close consultation with European industry; over 600 organisations have either attended meetings with the Commission or sent written comments on the draft documents. The aim of the consultation has been to create a programme that would provide support to application research activities that are of direct use to European industry.

Hierarchical logical structure and hypertext links are complementary and can be combined to build more powerful document management systems. Previous work exploits this complementarity for building better document processors, browsers and editing tools, but not for building sophisticated querying mechanisms. Querying in hypertext has been a requirement since [19] and has already been elaborated in many hypertext systems, but has not yet been used for hypertext systems superimposed on an underlying hierarchical logical structure. In this paper we use the model and the SQL-like query language of [10] in order to manage structured documents with hypertext links. The model represents a structured documents with hypertext links. The model represents a structured document with typed links as a complex object, and uses paths through the document structure, as first class citizens in formulating queries. Several examples of queries illustrate, from a practical point of view, the expressive power of the language to retrieve documents, even without exact knowledge of their structure in a simple and homogeneous fashion. It must be stressed that the proposed model and language implement the equivalent HyTime Location Address Module. In fact, the language is more powerful than the corresponding HyQ query facilities. The implementation and the description throughout the paper use the SGML standard to represent the document structure and the object-oriented DBMS O2 to implement the query language and the storage module.

This paper reports on the development of a hypermedia environment for public access in a museum. It discusses problems encountered when making video interactive and multilineal and when linking video and text in the creation of the system. Through the exchange of properties between print and vidtm, media approaches to linking and continuity are presented. Visual examples are used to illustrate this and related to the need to further develop aesthetic and rhetorical aspects of linking video in hypermedia.

Numerous market and industry segments are becoming increasingly interested in hypermedia. For example, hypermedia is a fundamental cornerstone in electronic publishing, electronic performance support systems, and interactive entertainment. Most of the current state of the art in hypermedia is being defined by research which is conducted in universities and research institutions. Yet many of the hypermedia systems that are in use today by industry are first generation systems, often at least five years old. This begs the question: just how important is leading edge hypermedia technology to the private sector?

In semantically rich hypertexts it is attractive to enable presentation of a network of nodes and link at different levels of abstraction. It is also important that the user can interact with the hypertext using a command repertoire that reflects the chosen abstraction level. Based on a characterization of rich hypertext we introduce the concept of an interaction engine that governs the separation between internal hypertext representation and external screen presentation. This separation is the key principle of the HyperPro system. The HyperPro interaction engine is based on simple rules for presentation, interpretation of events, and menu set up. Much of the power of the interaction engine framework comes from the organization of these rules relative to the type of hierarchy of nodes and links, and relative to a hierarchy of so-called interaction schemes. The primary application domain discussed in the paper is program development and program documentation.

The emergent nature of structure is a crucial, but often ignored, constraint on authoring hypertexts. VIKI is a spatial hypertext system that supports the emergent qualities of structure and the abstractions that guide its creation. We have found that a visual/spatial metaphor for hypertext allows people to express the nuances of structure, especialy ambiguous, partial, or emerging structure, more easily. VIKI supports interpretation of a collected body of materials, a task that becomes increasingly important with the availability of on-line information sources. The tool's data model includes semi-structured objects, collections that provide the basis for spatial navigation, and object composites, all of which may evolve into types. A spatial parser supports this evolution and enhances user interaction with changing, visually apparent organizations.

Key problems of version support for hypertext systems arise from the fine-grained, heavily interlinked structure of hyperdocuments. Integration of version support aggravates cognitive overhead problems during version creation and disorientation during version selection. Starting from the need to support versioning in our hypermedia publishing environment, we designed the CoVer hypermedia version. server. CoVer maintains context information with the versions that guides version creation and in particular helps in version identification. The key concept is task tracking: Users change their network in order to perform a task. These tasks can guide meaningful, automatic version creation. Being stored persistently as contextual version information they serve version identification. Moreover, CoVer maintains the derivation history of hyperdocuments across document boundaries and tracks the influence of annotations on the creation of new versions and the start-up of new tasks.
